Function unlocking method and system based on fingerprint

Abstract

The embodiment of the invention discloses a function unlocking method based on a fingerprint. The function unlocking method comprises the following steps: collecting fingerprint information input onto a preset fingerprint acquisition device within a preset continuous time period; extracting target fingerprint characteristic information from the collected fingerprint information, and carrying out statistics and analysis on the collected fingerprint information to obtain target fingerprint trajectory information in the continuous time period; judging whether the target fingerprint characteristic information is matched with prestored fingerprint characteristic information or not, and judging whether the target fingerprint trajectory information is matched with the prestored fingerprint characteristic information or not; and when a judgment result shows that the target fingerprint characteristic information is matched with prestored fingerprint characteristic information and the target fingerprint trajectory information is matched with the prestored fingerprint characteristic information, unlocking a current locked function. Correspondingly, the invention also discloses a function unlocking system based on the fingerprint. A situation that pattern information is generated and a user is prompted to necessarily slide according to a built-in sliding direction is avoided, unlocking efficiency is improved, unlocking safety is further improved, and function unlocking can be conveniently and safely realized, and user unlocking experience is improved.

Description

Technical field [0001] The invention relates to the field of computers, and in particular to a method and system for unlocking functions based on fingerprints. Background technique [0002] With the development of electronic technology and the Internet, mobile terminals have become more and more powerful. For example, as long as users install various client products on mobile terminals according to their own needs, they can get a lot of consulting information, and even stay at home. To accomplish many things, people's lives and entertainment are increasingly inseparable from electronic terminals. With the unification of mobile operating systems and hardware platforms, the homogeneity of software functions is becoming more and more serious. Continuous innovation and introduction of new and personalized software functions have become an important way to maintain the competitiveness of terminal products. [0003] Fingerprint identification is the identification by comparing the minut...

Problems solved by technology

[0003] Fingerprint identification is to identify by comparing the detailed feature points of different fingerprints. In the current existing technology, the application of fingerprint identification is mostly limited to identity verification, and fingerprint applications are rarely used in other fields other than security verification, such as fingerprint identification. Function unlocking, but the verification process is too simple; there are solutions in the prior art that, when combined with fingerprint verification, generate pattern information with a sliding direction, and prompt the user to slide according to the pattern information to unlock the function, but the solution It is necessary to generate pattern information and prompt the user to slide according to the built-in sliding direction, the unlocking efficiency is not high, and the unlocking experience is poor
