Password input method and mobile terminal using same

Abstract

The present invention relates to a password input method. The method mainly includes the following steps: providing a mobile terminal with a built-in service application, a graphic detection module, a graphic conversion module, and a graphic input conversion table, and the mobile terminal has a touch display screen; starting the service Application, the mobile terminal prompts the user to enter a password; the user confirms the input password; the user draws a graph on the touch screen, and the graph detection module detects the graph drawn by the user to form an analysis element; the graph detection module submits the analysis element to the graph conversion module , the graphics conversion module maps the analysis elements to a preset graphics input conversion table to obtain a converted character sequence. The present invention further provides a mobile terminal using the above method. Using the password input method of the present invention, the input method is simple and fast, which is very beneficial to user experience, and improves the security of password setting.

Description

【Technical field】 [0001] The invention relates to a password input method, in particular to a password input method using graphics input, and to a mobile terminal using the method. 【Background technique】 [0002] With the development of the operating system of the mobile terminal, the service applications running on the mobile terminal become more and more abundant. Some of these business applications involve the user's personal account information. Before using these services, the user needs to enter a password on the mobile terminal to use them. At this time, the user mainly presses the corresponding key code on the mobile terminal or clicks on the touch screen soft keyboard or Enter the password by handwriting characters. [0003] Yet, there is following shortcoming in the mode of this password input on mobile terminal: [0004] (1) The mobile terminal is small in size, and the keyboard area for the user to input the key code is smaller, which causes the user to enter t...

AI Technical Summary

Problems solved by technology

When entering a password containing multiple character forms, it is relatively easy to input on a personal computer keyboard, but for a mobile terminal, key conversion switching is required, which brings inconvenience to the user when using a service with account input on the mobile terminal. Deviating from the original intention of setting security passwords;

[0006] (3) The user needs to memorize the account password in the form of characters. If the password is more complicated, it will put forward higher requirements for the user's memory ability, which is especially difficult for elderly users;

[0007] (4) Passwords in the form of characters are easy to circulate, and there is a risk of leakage, which will bring potential risks to users;

[0008] (5) Today's mobile terminals, such as mobile phones, use touch screens as the mainstream display screens, and keyboards are used less and less, or even completely abandoned. According to the traditional password input method, you can only rely on virtual keyboards , the switching of the virtual keyboard and finger operation are difficult
