Abstract

The invention relates to a password input method, which mainly comprises the following steps that: a mobile terminal is provided, wherein the mobile terminal has built-in service application, a graphics detection module, a graphics conversion module and a graphics input conversion table, and has a touch display screen; the service application is started, and the mobile terminal prompts a user to input a password; the user confirms the input of the password; the user draws graphics on the touch display screen, and the graphics detection module detects the graphics drawn by the user to form analysis elements; and the graphics detection module submits the analysis elements to the graphics conversion module, and the graphics conversion module maps the analysis elements to the preset graphics input conversion table to obtain a converted character sequence. In addition, the invention provides the mobile terminal using the method. By the password input method provided by the invention, an input way is simple, convenient, fast and favorable for user experiences, and the password setting security is improved.

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.

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
