Definitions
- the present invention relates to the specific field of mail processing. It is particularly aimed at a franking machine enabling fast printing rates by obtaining an anticipated digital signature.
- Some of these data are fixed (serial number of the machine for example), other variables (format or requested service for example) and among these some are obtained very late, that is to say very little time prior to the printing of the postal imprint, such as the weight of the mail item that is obtained only once the mail item retrieved from the weigh module on the fly conventionally preceding the print module, which delays the calculation of the signature and therefore significantly affects the printing rate of these mail items.
- the PSD must calculate the signature and this computation requires at least 120 ms to which it is necessary add 50 ms for the construction of the footprint, which for a transport speed of 4m / s requires to leave an interval of nearly 70cm between the output of the weigh module on the fly and the print module.
- an interval is not acceptable in current machines where such an interval does not exceed 15cm and where the length of the transport device is an important factor in increasing the cost of a machine.
- the patent US 6,499,020 proposes a solution to this problem by acting on the profile of the transport speed of mail items to the printing area.
- the patent US 6,595,412 proposes another approach by limiting the calculation time of the signature by proceeding to a pre-calculation of this signature from the fixed or slightly variable data entering into its composition.
- the invention proposes to overcome this disadvantage with a franking machine implementing an early signature process for processing envelopes on the fly with particularly high rates, including more than 15,000 envelopes per hour.
- An object of the invention is also to allow this treatment without significant structural changes of the franking machine.
- variable data comprise only a code impression taken upstream of the weighing of a three-dimensional structure of the fibers of the article of mail.
- said fixed data comprise at least one serial number of said franking machine.
- said postal indicia is printed in the form of a two-dimensional bar code comprising said digital signature.
- the invention also relates to the franking machine for implementing the aforementioned method comprising at least one power supply module, a dynamic weighing module and a printing module incorporating a postal security device, characterized in that it comprises a device for digitizing the three-dimensional structure of the fibers of each mail item extracted from this supply module and in that said postal security device comprises means for producing a digital signature from an imprint code extracting said three-dimensional structure of the fibers of the mail article by means of said digitizing device.
- said device for digitizing the three-dimensional structure of the fibers of each mail piece is integrated in said feed module and said postal fingerprint is printed in the form of a two-dimensional bar code comprising said digital signature.
- the invention is based on the anticipation in the franking process of the calculation of the digital signature which is no longer carried out after weighing the mail article but before it, ie as soon as it leaves the the feeder. But at this level, only the fixed data of the postal footprint are available, and then make a signature from these fixed data alone would make the process of postage particularly vulnerable to any attack by a malicious person. This is why the inventors have imagined using the three-dimensional structure of the fibers of the article of mail to add to these fixed data data of eminently variable nature whose availability is assured very far upstream of the print module. Thus, the security is guaranteed or even strengthened and the digital signature can be calculated from the output of the power supply module, the distance between the weighing module and the print module is no longer a limitation for the print speeds.
- FIG. 1 very schematically shows the various constituents of a franking machine with, arranged upstream to downstream with respect to the advancing direction of the mail items, a mail item supply module 10, a dynamic weighing module (also called on-the-fly) 12, a postage module 14 with its print head 14A and conventionally provided with a postal security device (PSD) and a storage module 16 of the mailpieces freedmen.

- Such a machine can free mail items of different formats, from the American format No. 5 (76.2mm * 127mm) to the European format b4 (250mm * 353mm) through the European format C6 / 5 (114mm * 229mm) and this up to a determined thickness, for example 16 mm, corresponding to the height of the slot for introducing the mail items at the franking module.
- the power supply module is provided with a device 10A for scanning the three-dimensional structure of the fibers of the paper constituting the mailpiece.
- This fibrous structure in three dimensions which constitutes in a way the fingerprint of the paper, is unique (with a probability of 10 -150 of finding 2 identical codes) and different for each article of mail whether or not it has been elaborated. from the same ream of paper.
- Such a scanning device that allows processing at a speed of 20m / s is for example available from the English company Ingenia technology.
- a 3D scanning of a first mail piece is carried out and then the footprint code extracted from the three-dimensional structure identified is transmitted in a step 102 to the postal security device (PSD) of the machine which will then proceed in a step 104 by means of a secret key stored, as it is known, at the PSD calculation of the signature from this unique code and possibly fixed data known from the PSD such as the serial number of the franking machine, the date of franking (fixed for a given session), etc.
- PSD postal security device
- a step 106 the mail piece that left the feed module 10 for the dynamic weighing module 12 will be weighed on the fly and if necessary its determined format (according to the postal standard considered) so that the amount of postage can to be determined in a next step 108 from these data and data relating to the service (s) requested by the sender and entered beforehand.
- these often different variable data for each mail item are not taken into account for the calculation of the signature as it is known to do so to this day. Indeed, these data would not provide additional security for the development of the signature and would only delay its development.
- step 110 only to proceed at the level of the print module 14 to the printing of the postal fingerprint and digital signature previously prepared in step 104.
- the verification process for the mail item is as follows. At the office of reception of the mail, the person in charge of the postal administration who will receive the article of mail will proceed first, as he is accustomed, to the control of the received mail, in particular by checking the amount of franking compared in the format, weight and service (s) requested. But, he can also ensure the authenticity of the postage by decrypting the digital signature with his master key to remove the footprint code it contains and in comparing this decrypted code with that extracted from the received mail piece by means of a three-dimensional scanning device similar to that used in the mailing process of this article of mail.
- the simple introduction of a device for digitizing the three-dimensional structure of the fibers of mail items at the level of the feed module of the franking machine by enabling the drawing up of an anticipated signature is sufficient to allow to obtain very high printing rates without in any way limiting the safety of the machine thus equipped but on the contrary improving it.

Abstract
Description
La présente invention se rapporte au domaine spécifique du traitement de courrier. Elle vise tout particulièrement une machine d'affranchissement permettant des cadences d'impression rapides par l'obtention d'une signature numérique anticipée.The present invention relates to the specific field of mail processing. It is particularly aimed at a franking machine enabling fast printing rates by obtaining an anticipated digital signature.
Aujourd'hui, lorsqu'une machine d'affranchissement doit traiter des articles de courrier de différents poids, formats ou services (courrier dit mixed mail), elle est en général limitée en cadence d'impression. En effet, il est connu que l'administration impose que l'empreinte postale imprimée sur l'article de courrier porte une signature numérique. Or, pour augmenter la sécurité, les données signées sont de plus en plus nombreuses et comportent notamment : le numéro de série de la machine d'affranchissement, le format et le poids de l'article de courrier, la date et le montant d'affranchissement, les services demandés, etc. Et la signature ne peut être calculée qu'une fois toutes ces données transmises au dispositif postal de sécurité (PSD) de la machine. Certaines de ces données sont fixes (numéro de série de la machine par exemple), d'autres variables (format ou service demandé par exemple) et parmi ces dernières certaines sont obtenues très tardivement, c'est-à-dire très peu de temps avant l'impression de l'empreinte postale, comme le poids de l'article de courrier qui est obtenu seulement une fois l'article de courrier extrait du module de pesée à la volée précédant classiquement le module d'impression, ce qui retarde le calcul de la signature et influe donc notablement sur la cadence d'impression de ces articles de courrier.Today, when a postage meter has to process mail items of different weights, sizes or services (mixed mail), it is generally limited in print rate. Indeed, it is known that the administration requires that the postal imprint printed on the mail piece bears a digital signature. However, to increase security, signed data are increasingly numerous and include in particular: the serial number of the franking machine, the size and weight of the mail item, the date and the amount of postage, services requested, etc. And the signature can only be calculated once all this data is transmitted to the postal security device (PSD) of the machine. Some of these data are fixed (serial number of the machine for example), other variables (format or requested service for example) and among these some are obtained very late, that is to say very little time prior to the printing of the postal imprint, such as the weight of the mail item that is obtained only once the mail item retrieved from the weigh module on the fly conventionally preceding the print module, which delays the calculation of the signature and therefore significantly affects the printing rate of these mail items.
En effet, une fois cette donnée de poids obtenue, le PSD doit calculer la signature et ce calcul nécessite au moins 120 ms auquel il faut ajouter 50 ms pour la construction de l'empreinte, ce qui pour une vitesse de transport de 4m/s oblige à laisser un intervalle de près de 70cm entre la sortie du module de pesée à la volée et le module d'impression. Or, un tel intervalle n'est pas acceptable dans les machines actuelles où un tel intervalle n'excède pas 15cm et où la longueur du dispositif de transport est un facteur important d'accroissement du coût d'une machine.Indeed, once this data of weight obtained, the PSD must calculate the signature and this computation requires at least 120 ms to which it is necessary add 50 ms for the construction of the footprint, which for a transport speed of 4m / s requires to leave an interval of nearly 70cm between the output of the weigh module on the fly and the print module. However, such an interval is not acceptable in current machines where such an interval does not exceed 15cm and where the length of the transport device is an important factor in increasing the cost of a machine.
Le brevet
Toutefois, si l'une comme l'autre de ces solutions apporte une amélioration des cadences d'impression, cette amélioration reste limitée et ne permet pas des traitements à des cadences de l'ordre ou supérieures à 15 000 enveloppes par heure.However, if one of these solutions provides an improvement in printing rates, this improvement is limited and does not allow processing at rates of the order or greater than 15,000 envelopes per hour.
L'invention se propose de pallier cet inconvénient avec une machine d'affranchissement mettant en oeuvre un procédé de signature anticipée permettant un traitement d'enveloppes à la volée avec des cadences particulièrement élevées, notamment à plus de 15 000 enveloppes par heure. Un but de l'invention est aussi de permettre ce traitement sans modifications structurelles importantes de la machine d'affranchissement.The invention proposes to overcome this disadvantage with a franking machine implementing an early signature process for processing envelopes on the fly with particularly high rates, including more than 15,000 envelopes per hour. An object of the invention is also to allow this treatment without significant structural changes of the franking machine.
Ces buts sont atteints par un procédé d'élaboration d'une signature numérique au niveau d'une machine d'affranchissement dans lequel une empreinte postale est imprimée sur un article de courrier une fois celui-ci pesé et son montant d'affranchissement déterminé, cette empreinte postale étant associée à une signature numérique élaborée au moyen d'une clé secrète à partir de données fixes et variables, caractérisé en ce que lesdites données variables comportent uniquement un code d'empreinte extrait en amont_de la pesée d'une structure tridimensionnelle des fibres de l'article de courrier.These objects are achieved by a method of generating a digital signature at a franking machine in which a postal imprint is printed on a mail piece once it has been weighed and its franking amount determined, this postal fingerprint being associated with a digital signature elaborated by means of a secret key from fixed and variable data, characterized in that said variable data comprise only a code impression taken upstream of the weighing of a three-dimensional structure of the fibers of the article of mail.
Ainsi, avec la détermination préalable de la signature numérique dès ou avant l'entrée du module de pesée, il est possible d'obtenir des cadences d'impression particulièrement rapides, typiquement de l'ordre ou supérieures à 15 000 enveloppes par heure.Thus, with the preliminary determination of the digital signature from or before the entry of the weighing module, it is possible to obtain particularly fast printing rates, typically of the order of or greater than 15,000 envelopes per hour.
De préférence, lesdites données fixes comportent au moins un numéro de série de ladite machine d'affranchissement.Preferably, said fixed data comprise at least one serial number of said franking machine.
Avantageusement, ladite empreinte postale est imprimée sous la forme d'un code à barres à deux dimensions comportant ladite signature numérique.Advantageously, said postal indicia is printed in the form of a two-dimensional bar code comprising said digital signature.
L'invention concerne également la machine d'affranchissement pour la mise en oeuvre du procédé précité comportant au moins un module d'alimentation, un module de pesée dynamique et un module d'impression intégrant un dispositif postal de sécurité, caractérisée en ce qu'elle comporte un dispositif de numérisation de la structure tridimensionnelle des fibres de chaque article de courrier extrait de ce module d'alimentation et en ce que ledit dispositif postal de sécurité comporte des moyens pour élaborer une signature numérique à partir d'un code d'empreinte extrait de ladite structure tridimensionnelle des fibres de l'article de courrier au moyen dudit dispositif de numérisation.The invention also relates to the franking machine for implementing the aforementioned method comprising at least one power supply module, a dynamic weighing module and a printing module incorporating a postal security device, characterized in that it comprises a device for digitizing the three-dimensional structure of the fibers of each mail item extracted from this supply module and in that said postal security device comprises means for producing a digital signature from an imprint code extracting said three-dimensional structure of the fibers of the mail article by means of said digitizing device.
De préférence, ledit dispositif de numérisation de la structure tridimensionnelle des fibres de chaque article de courrier est intégré dans ledit module d'alimentation et ladite empreinte postale est imprimée sous la forme d'un code à barres à deux dimensions comportant ladite signature numérique.Preferably, said device for digitizing the three-dimensional structure of the fibers of each mail piece is integrated in said feed module and said postal fingerprint is printed in the form of a two-dimensional bar code comprising said digital signature.
D'autres caractéristiques et avantages de la présente invention ressortiront mieux de la description suivante, faite à titre indicatif et non limitatif, en regard des dessins annexés, sur lesquels:
- la figure 1 est une vue très schématique d'une machine d'affranchissement modifiée selon l'invention, et
- la figure 2 illustre le procédé d'affranchissement comportant le procédé d'élaboration de signature mis en oeuvre dans la machine d'affranchissement de la figure 1.
- FIG. 1 is a very diagrammatic view of a modified franking machine according to the invention, and
- FIG. 2 illustrates the franking method comprising the signature production method implemented in the franking machine of FIG. 1.
L'invention repose sur l'anticipation dans le processus d'affranchissement du calcul de la signature numérique qui n'est plus effectué après la pesée de l'article de courrier mais avant celle-ci, c'est à dire dès sa sortie de l'alimenteur. Mais à ce niveau, seules les données fixes de l'empreinte postale sont disponibles, et effectuer alors une signature à partir de ces seules données fixes rendrait le processus d'affranchissement particulièrement vulnérable à toute attaque d'une personne mal intentionnée. C'est pourquoi les inventeurs ont imaginé recourir à la structure tridimensionnelle des fibres de l'article de courrier pour ajouter à ces données fixes une donnée au caractère éminemment variable dont la disponibilité est assurée très en amont du module d'impression. Ainsi, la sécurité est garantie voire même renforcée et la signature numérique pouvant être calculée dès la sortie du module d'alimentation, la distance entre le module de pesée et le module d'impression ne constitue plus une limitation pour les cadences d'impression.The invention is based on the anticipation in the franking process of the calculation of the digital signature which is no longer carried out after weighing the mail article but before it, ie as soon as it leaves the the feeder. But at this level, only the fixed data of the postal footprint are available, and then make a signature from these fixed data alone would make the process of postage particularly vulnerable to any attack by a malicious person. This is why the inventors have imagined using the three-dimensional structure of the fibers of the article of mail to add to these fixed data data of eminently variable nature whose availability is assured very far upstream of the print module. Thus, the security is guaranteed or even strengthened and the digital signature can be calculated from the output of the power supply module, the distance between the weighing module and the print module is no longer a limitation for the print speeds.
La figure 1 montre de façon très schématique les différents constituants d'une machine d'affranchissement avec, disposés d'amont en aval par rapport à la direction d'avancée des articles de courrier, un module d'alimentation en articles de courrier 10, un module de pesée dynamique (dit aussi à la volée) 12, un module d'affranchissement 14 avec sa tête d'impression 14A et muni classiquement d'un dispositif postal de sécurité (PSD) et un module de stockage 16 des articles de courrier affranchis.FIG. 1 very schematically shows the various constituents of a franking machine with, arranged upstream to downstream with respect to the advancing direction of the mail items, a mail
Une telle machine peut affranchir des articles de courrier de différents formats, depuis le format américain N°5 (76,2mm*127mm) jusqu'au format européen b4 (250mm*353mm) en passant par le format européen C6/5 (114mm*229mm) et cela jusqu'à une épaisseur déterminée, par exemple 16 mm, correspondant à la hauteur de la fente d'introduction des articles de courrier au niveau du module d'affranchissement.Such a machine can free mail items of different formats, from the American format No. 5 (76.2mm * 127mm) to the European format b4 (250mm * 353mm) through the European format C6 / 5 (114mm * 229mm) and this up to a determined thickness, for example 16 mm, corresponding to the height of the slot for introducing the mail items at the franking module.
Selon l'invention, le module d'alimentation est muni d'un dispositif 10A de numérisation de la structure tridimensionnelle des fibres du papier constituant l'article de courrier. Cette structure fibreuse en trois dimensions qui constitue en quelque sorte l'empreinte digitale du papier est unique (avec une probabilité de 10-150 de trouver 2 codes identiques) et différente pour chaque article de courrier que celui-ci ait été ou non élaboré à partir d'une même rame de papier. Un tel dispositif de numérisation qui autorise des traitements à la vitesse de 20m/s est par exemple disponible auprès de la société anglaise Ingenia technology.According to the invention, the power supply module is provided with a
On va maintenant décrire le processus d'affranchissement mis en oeuvre dans un tel dispositif. Les articles de courrier étant disposés dans le module d'alimentation 10, il est procédé dans une première étape 100 à une numérisation 3D d'un premier article de courrier puis le code d'empreinte extrait de la structure tridimensionnelle relevée est transmis dans une étape 102 au dispositif postal de sécurité (PSD) de la machine qui va alors procéder dans une étape 104 au moyen d'un clé secrète stockée, comme il est connu, au niveau du PSD au calcul de la signature à partir de ce code unique et éventuellement de données fixes connues du PSD comme le numéro de série de la machine d'affranchissement, la date d'affranchissement (fixe pour une session donnée), etc.We will now describe the postage process implemented in such a device. As the mail items are arranged in the
Parallèlement, dans une étape 106 l'article de courrier qui a quitté le module d'alimentation 10 pour le module de pesée dynamique 12 va être pesé à la volée et si nécessaire son format déterminé (selon la norme postale considérée) de sorte que le montant d'affranchissement puisse être déterminé dans une étape suivante 108 à partir de ces données et de données relatives au(x) service(s) demandé(s) par l'expéditeur et saisies préalablement. Toutefois, ces données variables souvent différentes pour chaque article de courrier (à tout le moins pour deux lots distincts) ne sont pas prises en compte pour le calcul de la signature comme il est connu de le faire à ce jour. En effet, ces données n'apporteraient pas une sécurité supplémentaire pour l'élaboration de la signature et ne ferait que retarder son élaboration.At the same time, in a
Il ne reste plus, dans une étape 110, qu'à procéder au niveau du module d'impression 14 à l'impression de l'empreinte postale et de la signature numérique élaborée préalablement dans l'étape 104.It remains, in a
Ainsi, en anticipant le calcul de la signature numérique dès le module d'alimentation et non plus en sortie du module de pesée dynamique, on gagne 120 ms soit près de 48 cm à la vitesse de 4m/s. En outre, en recourant à un code d'empreinte par principe unique en lieu et place d'informations multiples, on améliore la sécurité globale du système.Thus, by anticipating the calculation of the digital signature from the power supply module and no longer at the output of the dynamic weighing module, we gain 120 ms or nearly 48 cm at the speed of 4 m / s. In addition, by using a single key imprint code instead of multiple information, the overall security of the system is improved.
On notera que s'il a été fait référence dans l'étape 110 d'impression finale à l'impression d'une empreinte postale, il est bien entendu que l'impression d'un code à barres à deux dimensions est tout aussi envisageable sous réserve d'avoir procédé préalablement à son calcul à partir des données ayant servies à l'impression de cette empreinte postale. On notera également que ce code 2D peut alors intégrer valablement la signature numérique.Note that if reference was made in the
Le processus de vérification de l'article de courrier est le suivant. Au bureau de réception du courrier, le préposé de l'administration postale qui réceptionnera l'article de courrier procédera d'abord, comme il en a l'habitude, au contrôle du courrier reçu, notamment en vérifiant le montant d'affranchissement par rapport au format, poids et service(s) demandé(s). Mais, il pourra en outre s'assurer de l'authenticité de l'empreinte postale en décryptant la signature numérique avec sa clé maître pour en retirer le code d'empreinte qu'elle renferme et en comparant ce code décrypté avec celui extrait de l'article de courrier reçu au moyen d'un dispositif de numérisation tridimensionnelle analogue à celui ayant servi au processus d'expédition de cet article de courrier.The verification process for the mail item is as follows. At the office of reception of the mail, the person in charge of the postal administration who will receive the article of mail will proceed first, as he is accustomed, to the control of the received mail, in particular by checking the amount of franking compared in the format, weight and service (s) requested. But, he can also ensure the authenticity of the postage by decrypting the digital signature with his master key to remove the footprint code it contains and in comparing this decrypted code with that extracted from the received mail piece by means of a three-dimensional scanning device similar to that used in the mailing process of this article of mail.
En effet, si l'empreinte postale a été contrefaite par photocopie sur un article de courrier autre que celui d'origine, le code extrait de la numérisation 3D sera différent de celui décrypté car les deux articles de courrier auront une structure fibreuse de papier distincte. Et même si le contrefacteur est en possession de son propre dispositif de numérisation tridimensionnelle, sa non connaissance de la clé secrète relative à un PSD autorisé aboutira à la création d'une signature erronée dont le décryptage par l'administration ne permettra pas une comparaison valide.In fact, if the postal imprint has been counterfeited by photocopy on a mail article other than the original one, the code extracted from the 3D digitization will be different from that decrypted because the two mail items will have a distinct paper fibrous structure. . And even if the infringer is in possession of his own three-dimensional scanning device, his knowledge of the secret key related to an authorized PSD will lead to the creation of an erroneous signature whose decryption by the administration will not allow a valid comparison. .
Ainsi, selon l'invention, la simple introduction d'un dispositif de numérisation de la structure tridimensionnelle des fibres des articles de courrier au niveau du module d'alimentation de la machine d'affranchissement en permettant l'élaboration d'une signature anticipée est suffisante pour permettre d'obtenir des cadences d'impression très élevées sans aucunement limiter la sécurité de la machine ainsi équipée mais au contraire en l'améliorant.Thus, according to the invention, the simple introduction of a device for digitizing the three-dimensional structure of the fibers of mail items at the level of the feed module of the franking machine by enabling the drawing up of an anticipated signature is sufficient to allow to obtain very high printing rates without in any way limiting the safety of the machine thus equipped but on the contrary improving it.
