and 5, after the data is successfully modified, adding a new block with repair information to the blockchain network to update the information, and acquiring the newly updated blockchain information by all nodes of the blockchain network to complete repair.
Further, the specific steps of step 1 are:
step 1.1, after the television is started for the first time, the television sends node information of the television to a super node of a block chain network;
step 1.2, the super node receives the node information to register and adds the node to a node list;
step 1.3, the super node broadcasts a new node list to other nodes of the whole network, and the other nodes update the node list;
and step 1.4, other nodes receive and update the node list to complete the registration of the new node.
Further, the own node information in step 1.1 includes own IP address and MAC information.
Further, the specific steps of step 2 are:
in step 2.1, the television checks whether the protected data is in error through CRC;
step 2.2, when the television detects that the protected data is wrong, the television generates a public key and a private key for encrypting the request information and broadcasts the public key to the whole network;
and 2.3, encrypting the request information for repairing the protected data by the television by using the generated public key, and broadcasting the encrypted request information in the blockchain network.
Further, after receiving the broadcasted encryption request information, the other node in step 3 decrypts the encryption request information by using the previously received public key of the node.
Further, step 2 and step 3 employ an AES encryption algorithm.
Further, the specific steps of step 4 are:
step 4.1, when the fault node receives correct protected data, a popup prompts a user that the local computer will carry out data restoration;
step 4.2, the fault node carries out data restoration and is directly restarted after completion;
and 4.3, after the failed node is normally displayed after restarting, the failed node sends feedback information to the node sending correct data to inform a user that the data is successfully repaired.
Further, in step 5, each tv node stores the blockchain information, and each tv node updates its respective node list synchronously with each other, and only accepts and retains the longest blockchain to the local computer.
Further, the newly added block in step 5 is added to the block chain after being agreed by a majority of nodes in the network.
Further, it also includes step 6, when the failed node is confirmed to be repaired successfully, the node sending the correct protected data is given corresponding excitation.
Further, the incentive includes a premium television service awarded for a certain length of time or a free movie ticket. By adopting the technical scheme, when the television is started for the first time, the television IP/MAC address/Mode can be automatically registered in the cloud, if the protected data of the software is lost or wrong, the television can start a self-detection software protected data area in a starting program, when the data determine that the error occurs, the television data can be encrypted and broadcasted to the cloud to request automatic repair, after any normal television of the same type on the cloud decrypts the information, the self-protected data starts to be transmitted back to the television with the problem, after the television with the problem receives the information about to be automatically repaired, a user determines whether the television is repaired, if the television determines to be automatically repaired, the television can be automatically started after the repair is finished, and the repair record can be added into a block chain after the television is admitted (excavated) on the network. The invention utilizes the technology of the block chain to enable the television to form a network by itself, and establishes the automatic repair function of the television on the basis of the network, thereby solving the problems of low efficiency and extra cost of manual repair in the prior art.
