Abstract

The invention provides a sliding type capacitance fingerprint identification method and system and an unblocking method of the sliding type capacitance fingerprint identification system. The sliding type capacitance fingerprint identification system comprises an electrode matrix, multiple analog scanning modules, an analog-digital conversion module and a processing module, wherein the electrode matrix is composed of multiple electrodes, the analog-digital conversion module is used for converting analog signals into digital signals, and the processing module is used for receiving the digital signals and identifying a formed code series. Each electrode is independently connected with the corresponding analog scanning module, and user fingerprint analog signals are obtained according to the changes of capacitance signals of the electrodes. The analog scanning modules, the analogue-digital conversion module and the processing module are connected in sequence. According to the sliding type capacitance fingerprint identification system, sliding type pressure sense and touch type capacitance identification are combined, it is guaranteed that the encryption effect is good enough, the system is simpler in structure and smaller in size, encryption methods and decryption methods are simple, and the encryption cost is effectively reduced.

Description

technical field [0001] The invention relates to fingerprint identification technology, in particular to a sliding capacitive fingerprint identification method, system and unlocking method of the system. Background technique [0002] With the iPhone 5s implanted with fingerprint recognition, more and more terminal handheld devices have begun to incorporate this efficient and confidential hardware design. At present, common fingerprint recognition on the market mainly includes image fingerprint recognition, acoustic wave detection fingerprint recognition, sliding pressure sensitive fingerprint recognition, and full-scan touch capacitive fingerprint recognition. For example, the existing capacitive fingerprint identification technology is specifically: there are many small electrodes, because the capacitance C=ε *ε0* S / d, where C (capacitance), ε, ε0 (dielectric constant), S (contact area ), d (contact distance). Therefore, different distances from the peaks and valleys of th...
