Abstract

Data is the last defense line of security, in order to prevent data loss, no matter where the data is stored, copied or transmitted, it is necessary to accurately detect the data type, and further clarify the form and encryption structure of the data transmission process to ensure the accuracy of the data, so as to prevent data leakage, take the data characteristics as the core, use transparent encryption and decryption technology as the leading, and According to the data element characteristics such as identity authentication, authority management, outgoing management, file audit and external device management, the terminal data is marked with attributes to form a data leakage prevention module with data function, so as to control the data in the whole life cycle from creation, storage, transmission, use to destruction, no matter whether the data is stored in the server, PC or mobile device, provide unified policy management, form ecological data chain with vital characteristics, and provide comprehensive protection system for file dynamic encryption transmission, such as prevention in advance, control in the event, and audit after the event, so as to ensure the security of dynamic encryption in the process of file transmission, ensure the core data of the file, and help the enterprise keep away from the risk of data leakage.
