The traditional computer has low computing efficiency, and the data processing mode is relatively single. However, the cloud computing technology has the ability of multiple information to accelerate data processing and can process the data in a short time. Therefore, by applying the cloud computing technology to the computer data processing, the speed and dynamic optimization technology of the cloud computing technology can effectively control the multi-source information data flow. At the same time, the cloud computing data processing service mode is built, which can integrate and reconstruct information resources, and solve the problem of computer resource scheduling. However, to prevent technology leakage, architectural security protocols are needed, and new encryption technologies are developed to reduce the cost of data operation as much as possible while ensuring the application security of cloud computing technology.
