With the advent of the information age, the amount of electronic information is exploding, and traditional local storage methods are no longer able to meet the storage needs of massive data. At the same time, data security issues are becoming increasingly prominent, with risks such as data leakage and loss constantly threatening users information security. This paper proposes a design scheme for a cloud computing based mobile communication electronic information storage and sharing platform. This platform aims to integrate cloud computing technology to achieve efficient storage, secure management, and convenient sharing of electronic information, meeting the diverse needs of users. In order to provide strong support for the informationization process of modern society.
