An Image Access Control Scheme in the Blockchain Environment
Xin Zhou, Zhaowen Lin, Junfei Huang · 2021 2nd International Conference on Electronics, Communications and Information Technology (CECIT) · 2021
Aiming at the current storage and access problems of image resources, this article proposes a scheme for implementing fine-grained image access control in a blockchain environment. According to the characteristics of image files, this solution introduces a distributed storage system outside the blockchain, and designs a storage and access control mechanism based on identity attributes to encrypt the storage index of the image and upload it to the blockchain. Users who satisfy the attribute access structure can decrypt index information and obtain image resources, realizing a safe and effective access control scheme.
