Problems solved by technology

Data encryption is to make the same data encrypted by the user using the user's private key become different, while the de-redundancy technology uses the similarity of the data, so the de-redundancy problem of encrypted data needs to be solved

Abstract

The invention provides a security storage method based on identity authentication. The method comprises the steps of using the self file by a file owner of a cloud platform through a mobile terminal; carrying out ownership authentication on other users before elimination of redundancy; after the user become a file owner, recording the user by the cloud platform, and enabling the file owner to take back the own file; enabling illegal users who do not own files to be unable to acquire user files and user private keys by using the cloud platform; and enabling the file owners to decide whether other users are the owners of the files or not, and eliminating redundancy of the files which are encrypted by the different user private keys through secondary encryption. After the method is used, the illegal users can not acquire the data ownership, and the users can freely select the private keys while redundancy of the encrypted data is eliminated.

Description

technical field [0001] The invention relates to cloud security, in particular to an identity authentication-based safe storage method. Background technique [0002] Cloud storage services can back up files in real time and synchronize and share files anytime, anywhere. But cloud storage also faces many challenges. User data security in cloud storage is a fundamental issue. Since the cloud storage provider is commercial in nature, the cloud storage server is not trusted, and it must be ensured that the cloud platform cannot obtain user data. The existing method is to encrypt the data before the user uploads it to the cloud platform, so that only the user can decrypt it. On the other hand, the rapid development of cloud storage leads to the rapid growth of storage space, and efficient storage is another problem in cloud storage. The de-redundancy technology adopted by most cloud storage providers is an effective way to reduce storage space and transmission bandwidth. Howe...
