The invention relates to an any handwriting graphical password method used for a payment system. The method comprises a password setting step and a password verification step by taking a touch screen as graphical password input equipment, wherein the password setting step comprises the following steps of: receiving any handwriting graph input by a user via the touch screen; carrying out characteristic extracting and coding on any input handwriting graph; receiving the handwriting graph input by the user again via the touch screen; carrying out characteristic extracting and coding on the handwriting graph input for the second time; comparing the input of two times to judge the graphical password input effectiveness. The password verification step comprises the following steps of: receiving any handwriting graph input by the user via the touch screen; carrying out characteristic extracting and coding on the input handwriting graph; carrying out communication encryption on graph password; transmitting the graph password to a data center; comparing the graph password with the graph password of the data center to judge whether the two graph passwords are same or not; if so, passing the verification. Compared with the prior art, the handwriting graphical password method used for the payment system, which is disclosed by the invention, has the advantages of high encryption intensity, easiness in memorizing and managing and the like.
Description
technical field [0001] The invention relates to a payment system security technology, in particular to a handwritten arbitrary graphic password method used in the payment system. Background technique [0002] In recent years, with the development of mobile communication technology, the number of users who pay through mobile phones or other mobile terminals has exploded, but its security cannot be guaranteed, and there are constant reports of users suffering losses. The reason is mainly that traditional digital passwords (for example, banks use 6-digit numbers as passwords) are extremely vulnerable to attacks by hackers or phishing websites, and it is easy to obtain user passwords. How to crack the security of mobile payment has become an urgent problem to be solved. [0003] In addition, there are now a huge number of various bank cards, credit cards, consumer cards, payment cards, etc. Individuals often have a large number of various cards, and their passwords are composed...
