Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0033] see figure 1 As shown, the present invention provides a biometric-based intelligent terminal unlocking method, which ensures the security of user biometric-related information while implementing identity authentication for users, and avoids leakage of user biometric information. The biometric-based intelligent terminal unlocking method of the present invention specifically includes a registration method and an unlocking method.
[0034] see figure 1 As indicated, for registration, specifically:
[0035] S11: The terminal device acquires the biometric information of the user. Terminal devices are, but not limited to, smart phones, computers, and tablet computers, and biometric information collection sensors are integrated or externally connected to the terminal devices. The biometric information includes one or more biometric informa...

The invention discloses an intelligent terminal unlocking method and system based on biological characteristics, and relates to the field of intelligent terminal security. The method includes registration and unlocking. The registration comprises the following steps: terminal equipment acquiring biological characteristic information of a user; calculating the biological characteristic informationby using a first preset algorithm to generate high-entropy data; inputting the high-entropy data into a second preset algorithm for processing to obtain verification data; the unlocking method comprises the following steps: the terminal equipment acquires service request information sent by the user, and acquires biological characteristic information of the user contained in the service request information; calculating the biological characteristic information in the service request information by using a first preset algorithm to generate unlocking high-entropy data; and inputting the unlocking high-entropy data into a second preset algorithm for processing to obtain unlocking verification data, and judging whether the unlocking verification data is the same as the verification data or not. The method can guarantee the safety of the biological characteristic information of the user.
Description
technical field [0001] The present invention relates to the field of intelligent terminal security, in particular to a biological feature-based intelligent terminal unlocking method and a biological feature-based intelligent terminal unlocking system. Background technique [0002] Biometrics technology is the close combination of high-tech means such as computer and optics, acoustics, biosensors and biostatistics, and uses the inherent biological characteristics of the human body, such as fingerprints, faces, irises, voices, etc. to identify personal identities. It has been widely used in smart device unlocking, mobile payment authentication and other fields. [0003] At present, the biometric technology needs to store the user's biometric information in the terminal device or server, which may cause the leakage of the user's biometric information and bring information security risks to the user. Contents of the invention [0004] In view of the defects in the prior art, ...
