Abstract
Description
technical field
[0001] The invention relates to the technical field of fingerprint processing, in particular to a picture processing method and a terminal device for preventing fingerprint information leakage. Background technique
[0002] Fingerprints are raised lines on the skin. Because human fingerprints are produced by the joint action of heredity and environment, everyone has fingerprints, but they are different. Because the fingerprint repetition rate is extremely small, about one in 15 billion, it is called "human ID card". Fingerprints are the lines formed by the bumpy skin on the pads of human fingers. Fingerprints can increase the friction force when the hand touches objects, making it easier to exert force and grasp objects. It is naturally formed in the process of human evolution. In the process of skin development, although the epidermis, dermis, and matrix layers are all growing together, the soft subcutaneous tissue grows relatively faster than the hard epi...
