Embodiment Construction

[0092] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0093] The block chain-based access control method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the administrator terminal 101, the visitor terminal 103, the blockchain server 104 and the unlocking terminal 105 communicate with the access control server 102 through the network. The access control server 102 obtains the unlocking permission setting request, and the unlocking permission setting request includes visitor identity information; downloads the biometric data ciphertext from the biometric database a...

Abstract

The invention relates to a blockchain-based access control method and device. The method comprises the steps of: obtaining an unlocking permission setting request, wherein the unlocking permission setting request comprises visitor identity information; downloading a biological feature data ciphertext from a biological feature database and downloading a subkey ciphertext from a blockchain server according to the visitor identity information; sending the unlocking permission setting request and the subkey ciphertext to a preset number of administrator terminals; obtaining subkeys decrypted by the preset number of administrator terminals, and restoring the key according to the subkeys; decrypting the biological feature data ciphertext via the key to obtain biological feature data, wherein thekey is destroyed after the biological feature data are obtained; and sending the biological feature data to an unlocking terminal, wherein the unlocking terminal performs unlocking according to the biological feature data. By adopting the method, the safety of the biological feature data for smart locks can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a blockchain-based access control method and device. Background technique [0002] With the application of emerging technologies such as face recognition technology and cloud network platform in access control lock products, smart access control locks are becoming more and more popular among users. Smart home products. At present, smart access control locks are widely used in banks, government departments (focusing on security), large enterprises and other places. At the same time, human biometric data (such as fingerprint data and face data), as the core of biometric identification technology, has the characteristics of uniqueness and lifelong invariance. Therefore, using biometric data as an important technical means for human identity confirmation has the security High reliability, no loss and damage. Biometric identification technology is a mature technology fo...
