As shown in fig. 1, a self-media data uplink method by means of an intelligent contract, the method comprises steps S101-S107.
S101, a block link node receives a self-media data uplink request sent by a first client, wherein the self-media data uplink request comprises self-media data encrypted by a public key of the first client.
And S102, triggering a verification intelligent contract, verifying the identity of the first client by the verification intelligent contract, and executing the uplink process of the self-media data after the verification is passed.
S103, the block chain node receives the query request of the self-media data of the second client.
And S104, triggering a verification intelligent contract, and verifying the identity of the second client by the verification intelligent contract.
And S105, after the verification is passed, the block link nodes send the self-media data query request to the first client, wherein the self-media data query request comprises a second client public key, so that the first client encrypts the self-media data by using the second client public key.
And S106, the block chain node receives a self-media data query response sent by the first client, wherein the self-media data query response comprises self-media data encrypted by a public key of the second client.
And S107, triggering a verification intelligent contract, verifying the identity of the first client by the verification intelligent contract, and executing the uplink process on the self-media data encrypted by the public key of the second client after the verification is passed.
In one example, the method further comprises: the block chain node receives a self-media data query request sent by the second client; and the block chain node sends a self-media data query response to the second client, wherein the self-media data query response comprises self-media data encrypted by the public key of the second client, so that the second client can decrypt the self-media data encrypted by the public key of the second client by using a self private key.
In an example, the self-media data is operation data of a user on a self-media platform corresponding to the first client, and includes self-media content, user operation time, and user operation times.
In one example, the first client encrypts the self-media data with a self public key, specifically: and the first client encrypts the self-media data by using a self public key according to a preset proportion.
In one example, the self-media data includes an associated attribute and a non-associated attribute; and automatically superposing the attribute values of the self-media data associated attributes.
In the above example, the first client acts as an operator of the self-media data, and the second client acts as a querier of the self-media data; for a particular self-media platform, each user may be either an operator of the self-media data or a querier of the self-media data.
The above-mentioned method for uplink transmission of self-media data is described below with reference to fig. 2, and the method includes steps S201 to S214.

Further, the self-media data includes two attributes, an associated attribute and a non-associated attribute. For example: the user self-media operation time belongs to the non-associated attribute, and the self-media operation time of each user can be stored in the block chain; for example: the number of times of displaying the self-media data is the associated attribute, the data format of the self-media data comprises the number of times of displaying the self-media, and the attribute values of the number of times of displaying the self-media can be automatically superposed as long as other users see the self-media data from respective terminals.
The self-media type comprises characters, pictures and small videos which are displayed or disclosed by a user, or any combination data of the characters, the pictures and the small videos, and the self-media data generated by the user can be stored on a chain and cannot be tampered, so that the authenticity of the data is guaranteed. The situation that the number of self-media displays is increased randomly from the media platform can be avoided; thereby improving the user experience.
S202, the first ue sends a request for uplink from media data to the blockchain node.
And S203, triggering a check intelligent contract on the block chain, checking the identity of the first client by the check intelligent contract, and executing the uplink process of the self-media data.
The checking means that whether the first client is a user of the self-media platform is judged, and only the user of the self-media platform can have the authority to uplink the self-media data.
It should be noted that the uplink process is a conventional process in the art and will not be described in detail. For example: and under the workload certification PoW common mode, packaging and verifying the data, wherein the block link point of the account right can place the packaged block in the next block of the current block as a new block uplink.
S204, the block node sends a ul response from the media data to the first ue.
S205, the second client sends a self-media data query request to the block link point, wherein the self-media data query request comprises a public key of the second client.
At this time, the user corresponding to the second client may query the self-media data after seeing the self-media data. In the application, the first client and the second client are both terminal devices provided with decentralized application software, and can directly perform information interaction with the blockchain nodes on the blockchain.
And S206, triggering a check intelligent contract on the block chain, wherein the check intelligent contract checks the identity of the second client.
After the verification is passed, executing the next flow; the check fails and the process terminates.
And S207, after the verification is passed, the block link node sends a self-media data query request to the first client, wherein the self-media data query request comprises a public key of the second client.
And S208, the first client encrypts the self-media data by using the second client public key.
S209, the first client sends a self-media data query response to the blockchain node, where the self-media data query response includes the self-media data encrypted by the public key of the second client.
S210, triggering a check intelligent contract on the blockchain, where the check intelligent contract checks the identity of the first client and performs a cochain procedure on the self-media data encrypted by the public key of the second client.
S211, the block node sends a query response from the media data to the second ue.
S212, the second client sends a query request for media data to the blockchain node.
S213, the block node sends the self-media data query response to the second client, where the self-media data query response includes the self-media data encrypted by the public key of the second client.
And S214, the second client decrypts the self-media data encrypted by the public key of the second client by using the self-private key to obtain the self-media data.
According to the method and the device, the data of the self-media can be linked up, the link up process is public and transparent, and any user of the same self-media platform can view the self-media data; the authenticity of the self-media data is guaranteed. In addition, the user can encrypt or not encrypt the self-media data according to the preference of the user, and the user experience is improved.
It should be noted that, in the present application, a client directly performs information interaction with a node of a block chain, and the block chain node directly stores information on the block chain without a centralized server, so that self-media data is more open and reliable; rather than the existing client interacting with a centralized server.
