Cloud data modification method

Abstract

The invention provides a cloud data modification method, comprising: generating a random number when receiving a data modification request sent by a client; encrypting the random number with a private key to obtain authority verification data; sending the authority verification data to the client The terminal decrypts, so that the client uses the public key corresponding to the private key to decrypt the random number from the authority verification data, and uses the public key to encrypt the random number and new data to obtain the coverage data; receive the coverage data sent by the client; use The private key decrypts the random number and new data from the covered data; judges whether the random number has changed; if the random number has not changed, obtains the field names of all fields in the new data and the original data; compares the new data with the same fields in the original data The value corresponding to the name; if the value is different, the value corresponding to the same field name in the new data is written to the field corresponding to the same field name in the original data. The invention can prevent data from being modified illegally.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a cloud data modification method. Background technique [0002] Cloud storage space is used to provide users with online file storage, access, backup, sharing and other file management functions. Through the network disk, no matter where the user is, as long as they can connect to the Internet, they can manage the files stored in the cloud through the mobile terminal. [0003] However, since the cloud storage space will be connected to the Internet, there is data confidentiality and security. Once the account of the cloud storage space is leaked, it will pose a threat to the user's private data. At present, the existing cloud storage space does not have strong protection for the user's account, so the user's private data has a risk of leakage and is easily illegally modified by others. Contents of the invention [0004] The technical problem mainly solved by the present ...
