Second aspect, the data storage management system provided in an embodiment of the present invention based on cloud storage service device include:
Receiving module, for receiving the data of user's upload；
Judgment module judges whether the data are legal for the block head and common recognition algorithm according to the data, if
It is then to save the data；
Encrypting module generates the hash value of the data for encrypting to the data；
Sending module, for the data are sent to cloud storage service device and receive Cloud Server return the data
Storage address；
Update module obtains the hash value of the storage address and by the Hash of the data for utilizing hash algorithm
The hash value of value and the storage address is inserted into the account book of the data, is updated to the account book and will be to each calculating
This more new information of node feeding back.
Further, the system further include:
Setup module, for block head to be arranged for the data, wherein the block head includes the corresponding meter of the data
Hash value, timestamp and the random number of operator node information, Merkle tree root, the hash value of a upper data block, subsequent data chunk.
Data storage and management method and system provided in an embodiment of the present invention based on cloud storage service device has with following
Beneficial effect:
It crosses and upper transmitting file is audited and managed using the calculate node in block chain, according to common recognition machine while file uploads
More new block chain account book is made, realizes and whether maliciously being repaired for upper transmitting file is judged according to the format of file to before file storage
Change, reduces the number and cost of labor of the cryptographic Hash of calculation document entirety.
