An embodiment of the present invention provides a digital rights information processing method, which is applied to a user node, and fig. 1 is a first flowchart of the digital rights information processing method applied to the user node, as shown in fig. 1, including:
and S101, receiving a function request. Wherein the function request is for requesting at least one of the following functions: modifying the authentication function and the authentication function; the function request carries the work information and the user information.
The embodiment of the invention is suitable for a scene of requesting the functional service from the user node.
In the embodiment of the invention, a user node receives a function request, work information and user information; the work information and the user information are carried to the user node through the function request, and the user node provides a modification authentication function and an authentication function based on the function request.
In the embodiment of the invention, the modification authentication function is used for uploading the works to a block chain network for authentication after the authors modify the works.
In the embodiment of the invention, the authentication function is used for performing digital copyright authentication on works.
In the embodiment of the invention, the modification authentication function and the authentication function are both based on the work information and the user information; the work information comprises a work name and a work content file name; the name of the work is the name of the author to the work, the name of the content file of the work is the mark of the work, and in actual use, the work is controlled and managed according to the name of the content file of the work. The user information comprises a user name and a user password; the user name should be a real name. In practical use, the user information may further include a user nickname, and in order to better distinguish the user identities, the user nicknames corresponding to the multiple users should not be repeatable.
In the embodiment of the invention, before receiving the function request, the user node can also receive a user registration request, and the user registration request carries user information; when receiving a user registration request, the user node generates a user private key according to user information, wherein the user private key corresponds to the identity of a user. The private key (PrivateKey) is usually a string of hexadecimal characters, and the specific number of the characters should be determined according to the user requirement. Each private key corresponds to a public key, the public key is public and does not need to be kept secret, the private key is held by an individual, the public key and the private key can be mutually encrypted and decrypted, and in actual use, the private key can be used for authenticating the identity of a user.
In the embodiment of the invention, the private key is generated by adopting an elliptic encryption algorithm.
It can be understood that the user node can provide modification authentication function and authentication function according to the requirements of the user, the user can perform digital copyright authentication on works, the creation progress of the works can be recorded, the creation record of the works is reserved, and the works corresponding to each modified version can be verified, so that legal support can be provided by using the creation record in infringing official authorities related to digital copyright.
And S102, responding to the function request, and generating a copyright authentication record based on the work information and the user information.
The embodiment of the invention is suitable for authenticating the works and generating scenes of copyright authentication records after receiving the works information and the user information.
In the embodiment of the invention, the user node responds to the function request, and if the work information and the user information meet the authentication requirement, the copyright authentication record is generated based on the work information and the user information.
In the embodiment of the invention, the copyright authentication record is generated according to the name of the user, the password of the user, the name of the work and the file name of the content of the work, and the process of generating the copyright authentication record is different based on the work information and the user information if the function services requested by the function request are different. Illustratively, when a user needs to perform copyright authentication on a work, a user node receives a function request for requesting an authentication function, and work information and user information of the author which need to be authenticated; the method comprises the steps of firstly, processing the content of the work in the work information by adopting a simhash algorithm to generate a corresponding hash value.
