Payment equipment with high identification precision based on block chain technology

Abstract

The invention relates to payment equipment with high identification precision based on a block chain technology. The device comprises a main body, a base, a pedal, a top plate, an identification mechanism, a shielding mechanism, a display screen, a clamping groove, a light supplementing lamp and two side plates; a processor and a memory are arranged in the main body; the shielding mechanism comprises a baffle, a rotating assembly and two connecting assemblies. The rotating assembly comprises a first motor, a bearing, a lead screw, a moving block and a supporting rod. The recognition mechanismcomprises a lifting assembly, a lifting plate, a reciprocating assembly and a camera. According to the invention, a block chain technology is adopted for data storage, so the data safety degree is high, a stable illumination space is formed through the shielding mechanism, external interference is avoided, the recognition precision is improved, the position of the camera can be adjusted through the recognition mechanism, the camera is made to directly face the human face, the human face is shot from the front face, and the human face recognition precision is further improved.

Description

technical field [0001] The invention relates to a payment device with high identification accuracy 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 various payment devices used in people's daily life.

Problems solved by technology

[0004] The payment devices in the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, in order to facilitate the identification of the payment personnel, the existing payment devices are usually combined with some widely used face recognition technologies. Installing a face recognition camera on the payment device can facilitate the confirmation of the identity of the payer. At the same time, the payer can complete the payment without manually entering the password. However, when using the camera for face recognition, it is easily affected by the external environment and light. Interference, for example, in shopping malls or supermarkets with a lot of people, when performing face recognition, the recognition efficiency and recognition accuracy are likely to be reduced due to the complex background. Not only that, the position of the camera on the device is fixed, and some short or tall people When performing recognition, you need to look up or down, and the camera cannot face the face, which reduces its recognition accuracy, resulting in reduced practicability
