Embodiment Construction
[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0036] A handwritten arbitrary graphic password method for a payment system, the method uses a mobile phone, a tablet computer or other touch screen used for a payment terminal as a graphic password input device, and a graphic composed of one or more patterns handwritten by a user is used as the password, Improve security strength, easy to use. Figure I- figure 2 As shown, the method specifically includes a password setting step and a password verification step.
[0037] (1) Initial password setting: the touch screen receives any handwritten graphics input by the user, and ...

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 for a payment system. Background technique [0002] In recent years, with the development of mobile communication technology, the number of users who make payments through mobile phones or other mobile terminals has exploded, but its security cannot be guaranteed, and there are continuous reports of users suffering losses. The main reason is that traditional digital passwords (for example, banks use 6-digit numbers as passwords) are easily attacked by hackers or phishing websites, which can easily obtain user passwords. How to crack the security of mobile payment has become a problem that needs to be solved urgently. [0003] In addition, there are now a huge number of various bank cards, credit cards, consumption cards, payment cards, etc. Individuals often have a large number of various cards, and their passwords are compos...
