Problems solved by technology

[0002] With the rapid development of mobile devices and information technology, the functions of mobile devices are becoming more and more powerful, and many powerful programs can be installed on mobile devices. Mobile devices are widely used for various transaction processing, and user information security issues continue to As a result, since mobile devices do not have an external keyboard, especially the large-screen touch-sensitive mobile devices that are becoming more and more popular today, there is no hard keyboard, and the soft keyboard usually brings great inconvenience to the user's input due to the small screen.
Today there is an OTP (one-time password) that uses a third-party device to input a random password generated by the server to the user. This method is currently the most secure login method, but some users do not want a simple login process that requires a third-party devices, and there are many passwords that people need to remember in today's life, it is easy to confuse or even forget some passwords, and now there is an urgent need for a safe and convenient login system and method

Embodiment Construction

[0008] When the user registers and enters the registration page, the system will group the library according to the image (such as figure 1 ) pops up a dialog box for the user to set in turn, and each group of graphics in the group library has its own number, such as figure 1 An integer from 0 to N in is used as the key name of the password (key name). Such as figure 2 , each picture in each group of graphics is used as a one-bit password option, and the system defines a character value for each picture as the value of the password (value), such as figure 2 In A, B, C, D...L, the user has set up each group of graphics and the system will form a key-value pair (key-value pair) group according to the settings this time. This key-value pair group consists of The mobile terminal sends it to the server as the original password, such as image 3 1 in is a schematic diagram of the composition of the original password. After the server receives the original password, it stores t...

Abstract

A graphical dynamic password inputting and verifying method used for a touch screen mobile device without a keyboard is characterized in that a graphical recognition unit is used for replacing traditional digital recognition so that a user can remember conveniently, and each graph group has one code used for identifying the graph group. A password is generated according to the steps that options in each group are arranged in a user registration process; a system generates a corresponding character for each option; after a user finishes setting, a character array is formed; the system marks each character of the character array with one integer to form a key-value pair group which is used as an original password and transmitted to a server database to be saved. When the user logs in next time, a mobile terminal generates a random array randomly, and then reminds the user of inputting the password according to the graph code mapped by the random array. A server judges whether the password is input correctly according to the mapping relation between the original password matched with the random array and a sub password. By means of the graphical dynamic password inputting and verifying method, the passwords input by the user every time are basically different, and therefore the safety of the passwords is enhanced.

Description

technical field [0001] The invention relates to the field of computer software technology and information security, and is a random password login method with a C / S (client / server) structure, which is mainly used for large-screen touch mobile devices, such as mobile phones and tablet computers.
