Abstract: Big data technology is becoming more and more mature, and the application of big data has been springing up. The information security problems and information security events of big data are gradually emerging. The main content of this study is the security protection technology of the whole life cycle of data in the big data platforms, including data classification and classification, control of data access rights, data encryption protection for storage data, static data desensitization and dynamic data desensitization of data in the application process, and data access activities. Comprehensive log audit and data leak protection through sensitive data from business and terminal, provide data security protection in the whole life cycle process for data in big data platforms

Key words: big data, data life cycle, data classification and classification, data desensitization, data encryption, data leakage
