The embodiment of the present application provides the method that the data in a kind of pair of block chain are modified, as shown in Figure 1, this method
Include:
Step S101, data to be read are read from block chain.
It can be ready for use in SAAS application from the data to be read read in block chain for the embodiment of the present application
Data.In the embodiment of the present application, SAAS provider is that all-network infrastructure required for informationization and soft is built by enterprise
Part, hardware operate platform, and are responsible for a series of services, the enterprises such as the implementation of all early periods, the maintenance in later period and do not need to buy soft or hard
Part, construction computer room, recruitment IT personnel, can pass through internet use information system.Enterprise according to actual needs, provides to SAAS
Quotient's renting software service, wherein the software service leased from SAAS offer is SAAS application service.
For the embodiment of the present application, after reading data to be read in block chain, by the data read store to
It is local.
Step S102, the data read are decrypted.
For the embodiment of the present application, is stored using secret key pair to local data and be decrypted.In the embodiment of the present application,
It can be from the code key for locally obtaining the code key being locally stored or acquisition user's input.
For the embodiment of the present application, if the data read are that SAAS application needs data to be used, SAAS application can
To guide user to be decrypted using being stored in local secret key pair and be stored in the local data read by interface manner, and
Reading data after the form display decryption read.
Step S103, the data after decryption are verified.
For the embodiment of the present application, if the data read are SAAS, application needs data to be used, is answered based on SAAS
Rule is verified with available data, the data after decryption are verified.
Step S104, when carrying out verification failure to the data after decryption, push is directed to the check results of ciphertext data.
It wherein, include: revised data for the check results of ciphertext data.
For the embodiment of the present application, for the check results of ciphertext data further include: verify data, the verification failure of failure
The reason of at least one of.
For the embodiment of the present application, if the data read from block chain are that SAAS applies corresponding data, when right
