Input and verification method for hand texture information and input and verification device

Abstract

The invention discloses a hand texture information input method and verification method, an input device and a verification device. The input method comprises steps of collecting a hand image of a user, wherein the hand image of the user comprises the finger texture information and the palm texture information of the user; dividing the collected hand image of the user into a plurality of image regions, selecting a plurality of image regions meeting a preset input condition from the plurality of image regions, and extracting the feature information of a plurality of image regions; and storing the feature information of a plurality of image regions as a plurality of hand texture feature templates. According to the input method, the verification method, the input device and the verification device provided by the embodiment of the invention, the input and verification operation time of the user is saved, and input and verification efficiency of the user is improved; the collected hand image of the user comprises the finger texture information and the palm texture information of the user so that safety of the input method, the verification method, the input device and the verificationdevice is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of biological feature recognition, in particular to a method for entering and verifying hand texture information, a device for entering and a verification device. Background technique [0002] With the development of smart terminal technology, fingerprint entry and fingerprint recognition technologies have emerged. Fingerprint entry is to collect and store the user's fingerprint in advance. When the user performs fingerprint identification, the currently entered fingerprint is compared with the pre-stored fingerprint to verify the user's identity. [0003] However, the current fingerprint entry technology generally requires multiple touches of the user's finger with the entry interface to complete the entry of fingerprint data, and the fingerprint entry efficiency is low. In addition, when a user performs fingerprint authentication, the amount of characteristic information contained in a single fingerprint ...

Problems solved by technology

[0003] However, the current fingerprint entry technology usually requires multiple contacts between the user's finger and the entry interface to complete the entry of fingerprint data, and the fingerprint entry efficiency is low.

In addition, when a user performs fingerprint authentication, the amount of characteristic information contained in a single fingerprint data is limited, and there are still cases where the device is unlocked by mistake, and the user's identity authentication has security risks
