It is write according to recording, arriving its data record again by the angle for the whole flow process that the second client device is inquired, but this method
It is applicable to any other client device.Method 300 can for example including registration step (e.g., including the step of being subsequently noted
301-303), authorisation step (e.g., including the step 304-305 being subsequently noted), data storing steps (e.g., including below
The step 306-308 mentioned), data query step (e.g., including the step 309- step 314) that is subsequently noted and audit step
Suddenly (e.g., including the step 315) being subsequently noted.But specific application is depended on, during use, may only it relate to
And the part steps in the multiple steps in this method 300 including are (for example, it may be possible to only relate to registration step, authorisation step, data
One or more of storing step, data query step and audit steps).In addition, it is to be appreciated that according to practical application, the party
One or more steps in method 300 can be omitted, without departing from scope of the present invention.
In step 301, the registration request from the first client device is received.
In step 302, judge whether to receive the registration request of first customer equipment.For example, in one implementation, it can
The registration request is sent to each client device registered to block chain network, and in these other clients
In the case that the client device of more than half in equipment receives the registration request, receive the registration request, otherwise refuses the note
Volume request.
In step 303, in the case where receiving the registration request, the first client device is registered, is otherwise returned
Return error message.For example, register to the first client device may include as the distribution of the first client device for access region
The certificate of the modules on each block chain node in block chain network, and corresponding certificate is stored in block chain network
For to the progress authentication of the first client device in account book.It, should after the registration to first client device is completed
First client device just obtains the qualification that data sharing is participated in the block chain network.
In step 304, the authority distribution request from the first client device is received.
In step 305, upload permissions and/or access authority are distributed to the first client device.Upload permissions may include
Allow to upload the permission of data record, or does not allow to upload the permission of data record.Access authority may include for example only allowing to look into
See the permission of data record, only allow the permission of downloading data record or allow to check the permission recorded with downloading data etc..
Data about the upload permissions and/or access authority distributed to each chartered client device can be stored in block chain
In the account book of network (for example, permissions list in) in account book, for initiating to be directed to data record in corresponding client device
Upload request or access request when for corresponding client device upload permissions and access authority verify.
Within step 306, the upload for one or more data record from first client device is received to ask
It asks, wherein may include the quantity of logical card needed for accessing each data record in upload request.In one implementation, upload is asked
Seek the number of logical card needed for may specify the quantity of logical card needed for checking each data record and each data of downloading
Amount.In addition, the quantity for checking logical card needed for different data records specified in upload request can be different, and download not
The quantity of logical card needed for same data record can also be different.
In step 307, upload permissions verification is carried out to the first client device, to judge that first client device is
It is no that there is the permission for allowing to upload data record.
In step 308, the first client device have allow upload data record permission in the case where, by this one
Item or a plurality of data record are stored in the account book of block chain network, otherwise return to error message.For example, for each data
Record, should by the mark (for example, title of the first client device) and access of the data record and the first client device
The quantity of logical card needed for data record is collectively stored in the account book of block chain network.Due to the mark of the first client device
It is stored in together with data record in the account book of block chain network, therefore finds the data record in block chain network, just
It can determine that the data record is uploaded by the first client device, so that the first client device can not upload it
Data record denied.On the other hand, when the data record is checked or downloaded by other client devices, block chain link
Point can determine that the logical card for (checking or downloading) the corresponding quantity of the data record with access is distributed to the first client by needs
End equipment, rather than other client devices.Although being recorded in block chain network to data by taking the first client device as an example here
Account book in storage be illustrated, but it should be appreciated that for other client devices upload data record for, also need by
It corresponding data record and the mark of other client devices and accesses together with the quantity of logical card needed for the data record
It is stored in the account book of block chain network.
