Step S410: the entertainment platform receives an entertainment request which is initiated by an entertainment client and carries entertainment user identification, multimedia file identification and use right certification information.
The usage rights attestation information includes a usage rights issuer identification, a usage rights holder identification, and an authorization file identification. The usage rights issuer identification refers to a distributed identity of the copyright holder of a certain multimedia file. The authorized holder identification refers to a distributed identity that owns the usage rights of a certain multimedia file. The right issuer identification and the right holder identification are a decentralised verifiable distributed identity identification; the use right issuer identification is registered by a client where the issuer of the multimedia data is located and is stored in a blockchain service; the usage rights holder identification is registered by the client where the holder of the usage rights certification information is located and stored in the blockchain service. The identity can be prevented from being forged, tampered and deleted due to the decentralization characteristic of the blockchain service. The authorized file identification refers to an identification of a specific file authorized for use. The usage rights verification information may also include authorization time, download links, and other related information of the authorization file, as desired. Such as the singer of the song, etc.
The entertainment user identification is a distributed identity identification of the entertainment user and is obtained by applying for registration to the blockchain service. The distributed identity identifier (Decentralized Identifiers, DID) is a decentralised verifiable digital identifier, has the characteristics of being distributed, independently controllable, cross-chain multiplexing and the like, and can be used for automatically completing the registration, analysis, update or revocation of the DID. The DID resolves specifically into DID documents that include the unique identification code of the DID, the list of public keys and details of the public keys (holder, encryption algorithm, key status, etc.), and other attribute descriptions of the DID holder. The identity of different entertainment users is different, so that different entertainment users can be distinguished based on the entertainment user identity.
The multimedia file identification is identification information of a multimedia file, which may be in a compressed package, audio, video or text format, for example, music, video, novels, game installation packages, etc. The multimedia file identification may include a name, a unique identifier, etc. So that different multimedia files can be distinguished based on the multimedia file identification. When the user needs to open the multimedia file identification consistent with the authorized file identification, the corresponding multimedia file can be opened.
The usage rights certification information is generated at a terminal where the issuer of the multimedia file is located (i.e., usage rights issuer) and transmitted to the entertainment client. The entertainment client can be regarded as a terminal where the holder of the use right proving information is located, and can prove that a certain entertainment user has the use right of a certain multimedia file to the entertainment platform. The entertainment client may send the usage rights verification information to the entertainment platform when entertainment of the multimedia file is desired.
In one embodiment, the usage right certification information may be encrypted by the usage right issuer using a private key corresponding to the usage right issuer identifier, the usage right issuer sends the encrypted usage right certification information to the entertainment client, and then the entertainment client sends the entertainment user identifier, the multimedia file identifier, and the encrypted usage right certification information to the entertainment platform when a certain multimedia file needs to be opened.
Step S420: and the entertainment platform verifies the use right proving information according to the entertainment user identifier and the use right issuer identifier corresponding to the multimedia file identifier stored by the blockchain service.
The blockchain service may store the usage rights issuer identification corresponding to each multimedia file identification, and may also store the identity of all entertainment users who have completed registration. The entertainment platform can verify whether the entertainment user identifier initiating the entertainment request is one of the entertainment users who have completed registration, whether the multimedia file identifier requesting the entertainment is an authorized file identifier in the use right proving information, can verify whether the use right holder identifier in the use right proving information is consistent with the entertainment user identifier initiating the entertainment request, can verify whether the use right issuer identifier is consistent with the use right issuer identifier corresponding to the multimedia file identifier stored on the blockchain, and if so, the authentication is considered to be passed, and if not, the authentication is considered to be passed.
In one embodiment, when the usage right certification information is encrypted by the private key corresponding to the usage right issuer identification, the entertainment platform may further decrypt the usage right certification information by using the public key corresponding to the usage right issuer identification according to the usage right issuer identification corresponding to the multimedia file identification stored by the blockchain service.
For example, the issuer of song a may be a record company, and the usage right certification information encrypted by the private key of the record company can only be unlocked by the public key of the record company, so that the usage right certification information is encrypted and transmitted by the public key, which can further ensure that the usage right certification information is distributed by the record company and prevent from being tampered and forged.
Step S430: and if the verification is passed, the entertainment platform returns the multimedia data corresponding to the multimedia file identification to the entertainment client.
Wherein the multimedia data may be stored in an entertainment platform local database. If the local database has multimedia data corresponding to the multimedia file identification, directly returning the multimedia data to the entertainment client; if the local database does not have the multimedia data corresponding to the multimedia file identification, according to the download link in the use right certification information, the entertainment client can download the multimedia data corresponding to the multimedia file identification from the use right issuing end and send the downloaded multimedia data to the entertainment client.
In an embodiment, the entertainment client may send a file download request to the usage right issuer corresponding to the multimedia file identifier, where the file download request may include the usage right certification information, and may further include the multimedia file identifier, the entertainment user identifier, and so on. After receiving the file downloading request, the usage right issuing end can decrypt the usage right proving information by using the public key of the usage right issuing end, and verify whether the usage right proving information is consistent with the locally stored information, and if so, the usage right issuing end passes the verification and returns the multimedia data corresponding to the authorized file identifier. The entertainment client receives the multimedia data returned after the use right issuing end verifies the use right proving information; the multimedia data is sent to the entertainment client that initiated the entertainment request.
For example, the game manufacturer may be an issuer of the game installation package, the player may be a holder of the proof of use information of the game installation package, and the iOS platform, android platform, team platform, epic platform, PS platform, xbox platform may act as a verifier of the game installation package. The client side where the player is located can obtain corresponding download and installation packages on different platforms as long as the client side where the game manufacturer is located purchases the use right of a certain game (the use right certification information of the game is obtained).
For example, the record company of a song may be the issuer of the song, the user may be the holder of the usage rights proving information of the song, and the QQ music, the networkcloud music, the cool dog music platform may act as the verifier of the song. The user can obtain the corresponding song on different platforms as long as he purchases the right to use the song from the record company (obtaining the right to use proof information of the song).
According to the technical scheme provided by the embodiment of the application, the entertainment client side obtains the use right evidence information of the appointed multimedia file in advance, based on the use right evidence information, the entertainment client side obtains the use right of the multimedia file, an entertainment request can be initiated to different entertainment platforms, the entertainment platforms receive the entertainment request, the use right evidence information is verified, and the entertainment service can be provided after verification is passed, so that the entertainment client side can obtain the entertainment right of the multimedia file on a plurality of entertainment platforms without buying the entertainment right on a plurality of entertainment platforms respectively, the operation is simplified, and the resource consumption of the entertainment platforms is reduced.
Fig. 5 is a flowchart of an entertainment method of a multimedia file according to an embodiment of the present application. As shown in fig. 5, the method may be performed by the entertainment client, and the method includes: step S510-step S540.
Step S510: and the entertainment client sends the application information of the use right containing the multimedia file identifier and the entertainment user identifier to the use right issuing end corresponding to the multimedia file identifier according to the multimedia file identifier selected by the user.
The entertainment client can display a list of multimedia files, from which the user can click to select any one of the multimedia files, so that the entertainment client receives the multimedia file identification selected by the user. The entertainment client may determine a usage rights issuer identification corresponding to the multimedia file identification from the blockchain service or other device, and then send usage rights application information to the usage rights issuer corresponding to the usage rights issuer identification. The usage rights application information may include the multimedia file identification and an entertainment user identification of the entertainment client.
The entertainment user identifier can initiate a registration application of the digital identity to the blockchain service by the entertainment client, so that the entertainment user identifier is obtained.
Step S520: the entertainment client receives the use right evidence information returned by the use right issuing end according to the use right application information; the usage rights attestation information includes a usage rights issuer identification, a usage rights holder identification, and an authorization file identification.
Under normal conditions, the entertainment client applies for the use right proving information corresponding to the multimedia file identifier, so the authorized file identifier in the use right proving information returned by the use right issuing end is the multimedia file identifier. In order to distinguish the multimedia file identifier carried in the usage right certification information from the multimedia file identifier applied for certification by the entertainment client, the multimedia file identifier carried in the usage right certification information may be referred to as an authorized file identifier. The right of use issuing end can look for the right of use issuer identification that this multimedia file identification corresponds according to multimedia file identification and entertainment user identification in the right of use application information, and then pack this multimedia file identification, entertainment user identification and right of use issuer identification together and produce the right of use and prove information. For distinction, the multimedia file identification in the usage rights verification information may be referred to as an authorized file identification, and the entertainment user identification in the usage rights verification information may be referred to as a usage rights holder identification.
