Embodiment Construction
[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to specific embodiments and accompanying drawings.
[0026] The present invention aims at the problem of low recognition efficiency when the mobile terminal performs biometric identification. Embodiments of the present invention provide a biometric identification method and a mobile terminal. When the auxiliary verification information meets the preset conditions, it reduces The number of feature points that need to be matched reduces the number of biometric feature points that users need to enter, thereby improving the efficiency of biometric feature recognition.
[0027] Such as figure 1 As shown, the embodiment of the present invention provides a biometric identification method, which is applied to a mobile terminal. The mobile terminal may specifically be a smart phone, a tablet computer / PAD, ...

The invention provides a biological feature recognition method and a mobile terminal. The method aims to solve the problem that the mobile terminal is low in recognition efficiency when performing biological feature recognition. The method comprises the steps that auxiliary verification information is acquired, and whether the auxiliary verification information conforms to a preset condition is judged; if the auxiliary verification information conforms to the preset condition, when the quantity of feature points, matched with a preset biological feature template, in biological feature information reaches a first preset value, it is confirmed that recognition succeeds; and if the auxiliary verification information does not conform to the preset condition, when the quantity of the feature points, matched with the preset biological feature template, in the biological feature information reaches a second preset value, it is confirmed that recognition succeeds, wherein the second preset value is greater than the first preset value. Through the biological feature recognition method and the mobile terminal, when the auxiliary verification information conforms to the preset condition, thequantity of the feature points needing to be matched for biological feature recognition success is lowered, and therefore the speed and efficiency of biological feature recognition are improved.
Description
technical field [0001] The present invention relates to the technical field of communication applications, in particular to a biological feature identification method and a mobile terminal. Background technique [0002] Current mobile terminals have generally used biometric identification as device unlock credentials, such as fingerprint recognition, iris recognition, and facial recognition. It is reliable and safe, and saves the time and operation for users to input information, which is convenient and fast. [0003] When performing biometric identification, in order to ensure its security, a minimum identification standard will be set during identification verification. For example, fingerprint recognition and facial recognition. In order to meet the minimum recognition standard required by the user during verification, the user may need to adjust the entry posture to record the fingerprint of the entire face or the entire finger, and match enough feature points to unlock...
