Embodiment Construction

[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The password authentication method of the present invention is aimed at the existence of passwords in the prior art that have been recognized by eyes, and can leave scratches on the touch screen, and there is a risk of password leakage. Several identification information (such as numbers, characters or pictures) are randomly generated on the touch screen, and the user enters the password by clicking the identification information on the relevant position on the touch screen to realize the authentication of the password. Since the identification information generated on each touch screen can be different, The position of each identification information can also be different, so the position click...

Abstract

The invention discloses a password authentication method and a password authentication device, and in the password authentication implementation process, the password is difficult to be exposed, and is more safe and reliable. The method comprises the steps of receiving a standard password preset by users, wherein the standard password consists of characteristic values of a plurality of identification information; generating a plurality of identification information randomly on a touch screen when deblocking command is received, and recording the corresponding relationship between the position information of the identification information on the touch screen and the characteristic values of the identification information; acquiring the position information clicked on the touch screen, acquiring the characteristic values of the plurality of corresponding identification information according to a plurality of position information clicked by users, and forming a deblocking password input by users through the characteristic values of the plurality of identification information; and judging whether the deblocking password is identical to the standard password, if so, confirming that deblocking is successful, and if not, confirming that delocking is failed. The invention also discloses a password authentication device.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a password authentication method and device. Background technique [0002] With the continuous development of information technology, the information processing devices (such as computers, mobile phones or PDAs) used by people are becoming more and more intelligent. At the same time, people are paying more and more attention to the protection of personal privacy, and the identity authentication mechanism is also constantly upgrading. Among them, input password authentication and path authentication are currently widely used password authentication technologies. Path authentication is used in multiple applications on smartphones, such as Google's Jiugongge mobile phone screen unlocking. [0003] However, the method of password input authentication in the prior art is easy to be recognized by the eyes and easily cracked by brute force, while the method of path authe...
