Method for inputting graphic random passwords

Abstract

The invention discloses a method for inputting graphic random passwords, which relates to a password input method for a keyboard-less large-screen touch screen mobile device. The method is characterized in that a digital recognition unit for transmission is replaced by a graphic recognition unit which has no mutual logical relation with the digital recognition unit; and when a user enters into a password input unit, a view dialog box which is formed by n*m matrixes is popped up by a login program, the view dialog box is used for inputting passwords, a specific value defined by a graph is generated in a system memory after the graph is clicked by the user, the passwords can be formed after the graph is clicked by the user for a couple of times, the selection function can be stopped by a system if one click during a clicking process is long press, a dialog box can be hidden, the passwords can be transmitted to a background verification unit, the system can be logged in if the passwords are right, and the user can be noticed to input the passwords again if the passwords are wrong. When the user enters into a password selection dialog box for the next time, the matrixes in the password dialog box are rearranged, the positions clicked by the user when the user logs in the system in each time are random, graphs without mutual logical relations are additionally used for distinguishing, thus the passwords input in each time seem different by others, and the safety of the passwords is increased.

Description

technical field [0001] The invention is a random password input method for graphic recognition, which is mainly used for large-screen touch mobile devices, such as mobile phones, ipads and other mobile devices. Background technique [0002] Mobile devices are constantly developing in the direction of simple operation and complex functions. The login methods of some excellent programs, especially the programs that require the use of keyboards, can no longer be adapted to today's popular large-screen touch phones, and are replaced by soft keyboards. However, the soft keyboard is often difficult to operate, and sometimes it is very irritating, which makes users prefer to give up the complexity of the password and set a simple password, which has buried a great hidden danger to security. Later, gesture sliding password input appeared. method, but often because the touch screen is not sensitive, the user needs to repeat several times to input correctly. Mobile devices are used b...

Problems solved by technology

This method is to use numbers to distinguish the options, and the password is not confused enough. Peepers can quickly find out which item the user chooses, and each click is randomly sorted, which will allow the user to find the next one after each click. Clicking on the position of the target affects the coherence of the user's thinking and actions, and increases the complexity and time of input. Therefore, this method is not perfect and it is difficult to be widely used.
