Specifically, as shown in fig. 2, the present application provides a block chain-based digital rights protection method, including:

step 101: the data interaction system receives the work operation information and the work data information uploaded by the copyright owner, writes the work operation information into a linked list of the block chain, and transfers the work operation information to step 102, wherein the work operation information comprises transaction numbers of purchased works and operation modes corresponding to the transaction numbers.

Step 102: the data interaction detection system sends the work data information and the linked list to the distributed trust database and goes to step 103.

Step 103: and the distributed trust database receives the work data information and the linked list sent by the data interaction system, encrypts the work data information and the linked list and transfers to the step 104.

Step 104: the data interaction detection system receives an operation request initiated by a copyright access party, checks whether a transaction number and an operation mode carried in the operation request are matched with the work operation information recorded in the linked list or not, if yes, sends a request for acquiring the work data information to the distributed trust database, and then goes to step 105.

Step 105: the distributed trust database receives the request for obtaining the work data information sent by the data interaction detection system, decrypts and reads the corresponding work data information and the linked list, sends the read work data information and the read linked list to the data interaction detection system, and goes to step 106.

Step 106: the data interaction detection system receives the work data information and the linked list read out by the distributed trust database, and carries out consistency verification on the received linked list and the linked list in the block chain of the data interaction detection system; if the verification is correct, the data information of the works is sent to the copyright access party.

Optionally, before step 101, the method further comprises: and the data interaction detection system receives the permission of the block chain where the access linked list is located, which is granted by the copyright owner.

Specifically, in the above steps, only if the copyright owner grants the data interaction detection system right, the data interaction detection system can access and operate the work operation information stored in the blockchain.

It should be noted here that when the copyright owner wants to terminate the usage of the copyright for some reason, such as not wanting to continue the access of the copyright owner to the work, the access and operation of the copyright owner to the work can be terminated by revoking the right of the work in the data interaction detection system.

Optionally, before step 101, the method further comprises: the data interaction detection system and the distributed trust database receive a public key provided by a copyright owner.

Specifically, the public key at this time is provided for the copyright owner, and the technical scheme of the application adopts an asymmetric encryption algorithm, which is as follows: when a file is encrypted by using an asymmetric encryption algorithm, only a pair of matched public key and private key is used to complete the encryption and decryption process of a plaintext, for example, a public key is used to encrypt a file, a private key matched with the public key is used to decrypt the file, and a private key is used to encrypt a file, and a public key matched with the private key is used to decrypt the file.

Optionally, the operation mode corresponding to the transaction number in step 101 includes a hash value of the operation mode corresponding to the transaction number, a carrier storing the course operation information, a credential tag providing verification, and an encryption form.

Optionally, the operation mode corresponding to the transaction number in step 101 includes a type of operation and a number of operations.

Specifically, the work data information includes specific content of the work; the work operation information comprises operation information of a copyright owner and a copyright access party on works each time, wherein the specific work operation information comprises playing and downloading. The linked list is recorded on the blockchain, and comprises all verified blockchain transaction numbers and corresponding operation modes thereof, wherein the corresponding detailed information comprises: hash, Token, Signature and Encrypt, wherein the Hash represents a Hash value of a corresponding operation mode and is invisible to a database; token represents a carrier for storing the operation actions of the curriculum, and is visible to the database; signature represents a verification credential or tag; encrypt denotes an encrypted form of the work data information.

Optionally, in step 103, specifically: the distributed trust database encrypts the work data information and the linked list according to the provided private key; in step 105, specifically: the distributed trust database decrypts the work data information and the linked list stored in the distributed trust database according to the exchanged public key; in step 106, specifically: and the data interaction detection system carries out consistency verification on the linked list and the linked list recorded in the block chain of the data interaction detection system through a public key provided by a copyright owner.

In step 103, the distributed trust database encrypts the work data information and the linked list through a private key provided by the copyright owner and paired with the public key exchanged in step 101, and stores the encrypted form of the linked list in the distributed trust database, wherein the encrypted form of the linked list is Encrypt.

In step 104, specifically, after receiving the operation information initiated by the copyright accessing party, the data interaction detection system finds the linked list where the corresponding work operation information is located according to the transaction number sent by the copyright accessing party, and reads and checks whether the number and the type of all work operations stored by Token in the linked list correspond to the number and the type of the operation information initiated by the copyright accessing party one to one. Optionally, if the data interaction detection system finds that the operation information initiated by the copyright accessing party is inconsistent after checking, the data interaction detection system terminates the operation of the copyright accessing party on the works.

Optionally, in step 104, after receiving the operation request initiated by the copyright accessing party, the operation request initiated by the copyright accessing party is recorded in the blockchain of the data detection system.

Specifically, the copyright owner can also obtain the operation information record of the copyright access party on the corresponding course by calling the token value of the access course of the copyright access party in the database of the data interaction detection system, so that the copyright owner can master the operation process of the copyright access party, if the copyright access party relates to illegal operation information on works of the copyright owner and subsequently relates to infringement related matters, the access record mastered by the copyright access party can be used as an evidence for maintaining the right in the subsequent right maintaining process.

In step 106, the public key also has the function of verifying the digital signature, and the decrypted linked list is completely consistent with the linked list stored in the database of the data interaction system, so that the verification is correct. Specifically, a corresponding linked list is found through the transaction number, and whether all information in Token in the linked list is consistent with information in the singnature and corresponding information in the read linked list is verified.

The significance of the verification is as follows: firstly, confirming whether the work data information decrypted and read from the distributed trust database is required to be accessed by a copyright access party; secondly, whether the data information of the decrypted and read works is complete or not is confirmed, and if the data information of the decrypted and read works is incomplete, the operation performed by a copyright access party can not be completely realized; thirdly, the distributed trust database is not completely reliable and may be maliciously tampered, so that the read linked list and the original linked list are verified, and the effect of determining the required work data information is achieved.
