Architecture Design of Distributed Encrypted Storage and Computing Based on Fog Computing

With the progress of informatization, the problems of data transmission delay, untimely response and theft and tampering of user privacy data are becoming increasingly prominent. This paper proposes a distributed encryption storage and computing architecture based on fog computing, which uses the scalability and low latency of fog computing to solve the problems of data silos and response delays. Blockchain technology is introduced to build decentralized storage to prevent data tampering and ensure secure transmission and sharing. Hierarchical privacy protection measures are designed to store data in a hierarchical and classified manner to accurately control the scope of information acquisition. This method has good application characteristics and can effectively solve the problems of government data collection and calculation.
