Blockchain-technology-based smart bracelet with fingerprint recognition function

Abstract

The invention relates to a blockchain-technology-based smart bracelet with a fingerprint recognition function. The blockchain-technology-based smart bracelet comprises a main body, an identification mechanism, a display mechanism and two watch bands; the display mechanism comprises an opening, a protection plate, a telescopic component, a moving plate, a direction adjustment component and a display screen; the identification mechanism comprises a protective shell, a sealing block, a sealing plate, a hook and two fixing components. The blockchain-technology-based smart bracelet has the advantages that the blockchain technology is applied to data storage, and accordingly, the data security is high; through the identification mechanism, fingerprints of wearers can be identified, and others can be prevented from stealing the bracelet to damage the users' property security; after the fingerprints are identified successfully, the display mechanism can extend the display screen out of the opening to facilitate scanning payment; after payment, the display screen returns into the opening, and the protection plate blocks the opening to prevent the display screen against damage; therefore, the equipment practicality is improved.

Description

technical field [0001] The invention relates to a smart bracelet with fingerprint 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 mobile payment devices commonly used by people. [0004] Among all kinds of mobile payment devices, wristbands are faster and more convenient to use. The smart bracel...

Problems solved by technology

[0004] Among all kinds of mobile payment devices, wristbands are faster and more convenient to use. The smart bracelets in the prior art generally adopt traditional data encryption methods, which can easily cause data loss, and the payment QR code on the wristband is used to display the QR code. Most of the display screens are exposed to the outside and are easily damaged by external environments such as scratches, collisions, and extrusions. Not only that, but the existing smart bracelets lack the binding function. When someone else steals the bracelet, it is easy to use the bracelet to Payment, bring loss to the user's property, resulting in the reduction of the practicality of the existing smart bracelet
