Description of drawings
Fig. 1 is operation principle flow chart of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Shown in Figure 1, Fig. 1 is operation principle flow chart of the present invention.The invention provides the method for fast finding same file content in a kind of mobile phone, it is mainly used in solving, and under a plurality of catalogues of present mobile phone or same catalogue, the same file content need to be by manually distinguishing one by one, and existing backup and arrangement be the problem of trouble very.
The method of fast finding same file content in this mobile phone wherein comprises that specifically step is as follows:
At first will be according to the summary info of content of text correspondence establishment and text content Corresponding matching, the mode of specifically setting up summary info here has following two kinds;
One, according to message digest algorithm, content of text is carried out analytical calculation, obtain the informative abstract with this document content Corresponding matching, and correspondence is carried out record.
Message digest algorithm (MD5, Message-digest Algorithm 5) develops through MD2, MD3 and MD4.Its effect is to allow large capacity information be ' compressed ' into a kind of secret form before with digital signature software signature private key, exactly the byte serial of a random length is transformed into the large integer of a fixed length.No matter be MD2, MD4 or MD5, they all need the informative abstract that obtains the information of a random-length and produce one 128.
Increased " safety-belt " concept (safety-belts) due to MD5, although therefore MD5 is slower, safer a little than MD4 on the basis of MD4.In the MD5 algorithm, the size of information-summary and the necessary condition of filling and MD5 are identical.
Two, according to the cyclic redundancy check (CRC) algorithm, content of text is carried out analytical calculation, obtain the informative abstract with this document content Corresponding matching, and correspondence is carried out record.
Cyclic redundancy check (CRC) algorithm (CRC, Cyclic Redundancy Check/Code) is that a transmission block is carried out verification, is a kind of efficient error control method.
CRC check adopts the multinomial coding method, and multinomial multiplication and division calculating process is identical with the polynomial multiplication and division of common algebra, and polynomial signed magnitude arithmetic(al) is not advanced during plus-minus take 2 as mould, and dislocation is as the logic XOR.
