Abstract

The frequencies of commercial transactions or the kind of activities on a network system have been increased gradually such as transaction with credit cards, connecting onto a banking computer system, usage of vending machines, etc. For this purpose, this invention is a password algorithm system utilizing regularly varying elements such as hour, date, week day, month, etc. that change continuously and other kinds of elements so that the password changes according to the variable elements of time and other elements. In addition, by implementing dynamic variable elements being linked to user's ID, this invention disables the abuse of private information caught by someone on the Internet as ID. Someone who gets the data as ID but not its algorithm couldn't use it as it's not accepted in a server computer system.
