Password input method and device based on direction recognition

Abstract

The invention relates to the technical field of electronic security protection, in particular to a password input method and device based on direction recognition.The method includes the steps that a user interface is controlled to display a plurality of image-text areas, and a mapping relation between each image-text area and an information unit composed of a plurality of information elements exists; direction command information is obtained; the corresponding image-text area associated with the direction command information is judged according to the direction command information, so that the image-text area selected by a user is determined; the information unit mapped to the image-text area selected by the user is selected so that whether the content at the corresponding position of a preset password is an information element of the information unit or not can be verified.Therefore, by means of the method and device, the blur degree of password input can be greatly raised, accordingly safety of password setting / the input and verification process is improved, good operation convenience, coolness and fashion sense are achieved, and good user experience can be obtained when the use operates or uses the device.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic security protection, in particular to a password input method and device based on direction recognition. 【Background technique】 [0002] With the development of society, various security issues continue to occur, and human security awareness continues to increase. Nowadays, mobile terminals such as smartphones and tablet computers are widely used, usually with power-on passwords and password locks for private files. The application of the password safe input method, and therefore the safe password input method becomes particularly important, and is gradually applied to all aspects of life and work. For example, in mobile terminals, a display screen based on touch feedback is usually provided, and passwords can be input by touching keys to input numbers and passwords, taking pictures of faces to input passwords, and drawing lines in Jiugongge. These methods all have great deficiencies. Among ...

Problems solved by technology

These methods have great deficiencies. Among them, the way of inputting by touching keys and drawing lines in Jiugongge is easy to be peeped by others and reveal the password, and the password input by taking pictures of faces is easy to be cracked by static pictures.

It can be seen that none of the above methods have sufficient concealment and reliability, and are easy to be cracked

[0003] In the prior art, there are many schemes for realizing fuzzy password input. In one scheme, prompt characters are displayed on the first key, and the user guesses the second key where the real password character is based on the prompt characters. Through this indirect In order to achieve the purpose of fuzzy input, the mapping relationship undoubtedly increases the complexity, especially in some time-limited input applications, this scheme is inefficient

[0004] In other ways, multiple characters are provided in the same button, one of which is the correct password character. Once the user selects the button, according to the set relationship, the correct character entered by the user can be confirmed, so as to realize the password verification. Although the fuzzy input realized in this way is intuitive to the user, its concealment is relatively insufficient

[0005] In addition, the specific operation process of the solution described in the above-mentioned prior art is either directly selected through the touch screen, or the operation is realized by clicking the function keys set separately, which not only does not have better input masking Sex, also lacks a good sense of user experience
