Card swiping device with face recognition function based on block chain technology

Abstract

The invention relates to a card swiping device with face recognition function based on block chain technology, include a main body and a card slot, a main body is provided with an identification mechanism and two light blocking mechanism, an identification mechanism includes a swing assembly, a rotating assembly, a first connecting rod, a second connecting rod, a fixed shaft, a first ball, a camera and two anchor blocks, the rotating assembly includes a positioning lever, an air pump, a cylinder, a piston rod, a second ball and two positioning blocks, a telescopic assembly includes a connecting plate, two support blocks, two sliders, two telescopic frames, two third links, two fourth connecting rods and four connecting rods. The card swiping device with face recognition function based on the block chain technology has stronger convenience by adjusting the angle of the camera through the recognition mechanism, and the light blocking mechanism is used for blocking light in the recognition process to reduce the interference of strong light on the recognition accuracy, thereby improving the recognition accuracy of the card swiping device.

Description

technical field [0001] The invention relates to a card swiping device with face recognition function based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used, including the field of payment equipment. [0004] Card swiping devices in the prior art generally use traditional data encryption methods, which can easily cause data loss. More...

Problems solved by technology

[0004] Card swiping devices in the prior art generally use traditional data encryption methods, which can easily cause data loss. Moreover, the card swiping devices in the prior art require users to adjust their positions during the process of face recognition and verification, so that the face moves to In the identification area, the convenience of the existing card swiping equipment is greatly reduced. Not only that, if the existing card swiping equipment is exposed to strong light during the identification process, it is easy to cause identification errors and reduce the recognition accuracy of the existing card swiping equipment. Thereby reducing the market competitiveness of existing card swiping equipment
