Abstract

The invention discloses a method for protecting a right to be forgotten of a user through a digital watermarking technology. The method supports the user to outsource plaintext data, and ensures a cloud end to delete user data when receiving a request of the user, otherwise, a dishonest behavior of the cloud end is traced, so that the right to be forgotten of the user is maintained.

Description

technical field [0001] The invention relates to the technical fields of digital watermarking and cryptography, in particular to a method for protecting a user's right to be forgotten through digital watermarking technology. Background technique [0002] With the rapid growth of data volume, people's demand for storage space also increases sharply. Cloud storage technology came into being in this situation, and put forward the concept of storage as a service. Cloud storage provides users with cheap and sufficient storage space. People store their local data in the cloud and correspondingly lose control over their data. One day a user does not need important data stored in the cloud, so he asks the cloud server to completely delete his data. The cloud responds to the user that it has deleted the data, but the user cannot be sure that the cloud has really completely deleted his data. Moreover, the popular cloud storage structure backs up the data to prevent accidental disas...
