In a preferred embodiment, the data owner performs data storage through the intelligent terminal, including:
encrypting the data file by the data owner;
and generating a storage request through the intelligent terminal, and sending the storage request and the encrypted data file to the data server.
It can be understood that before the data file is stored, the data file needs to be encrypted (symmetric encryption algorithm), and after the data file is encrypted, a corresponding public key and a corresponding private key are obtained, the public key is stored in the data server, and the private key is shared with the sharing user.
In this embodiment, the storage request includes shared user information, a file time limit, and a public key. The public user information is used for verifying the authority of the data requester, and comprises biological information, equipment information, position information and the like; the file time limit represents the storage time of the encrypted data file in the storage server, and comprises permanence, one year, one day and the like.

The abnormality detection of the present embodiment includes virus detection and content detection; the virus detection is to screen the data file according to a built-in virus detection algorithm, and if the data file has viruses, the data file is cleaned; the content detection is to detect whether the content of the data file in the storage server changes, for example, the file name is modified, or the file content is increased, and then the data file can be isolated.
In a preferred embodiment, after the chain verification of the read request is passed, the user characteristic information of the data requester, the file time limit of the data file corresponding to the read request and the private key provided by the data requester are verified through the verification sequence.
And after the verification based on the verification sequence passes, the data server generates a control instruction and sends the control instruction to the corresponding storage server, and the corresponding storage server control instruction sends the target data to the data requester through the data server.
