Example one
Referring to fig. 1, a schematic diagram of steps of a batch distribution method for digital information provided in an embodiment of the present specification is shown, where the distribution method may include the following steps:
step 102: after the centralized server performs hash processing on the batch of digital information, writing a hash value into a block chain through an intelligent contract;
step 104: the distribution side requests the centralized server to take out the digital information;
step 106: the centralized server takes out the hash value from the block chain through an intelligent contract, finds out the corresponding digital information and sends the digital information to the distributor;
step 108: the distributor sends the digital information and the hash value to a receiver;
step 110: and the receiver performs on-chain inspection on the digital information and the hash value.
In step 106, the centralized server first determines the identity of the distributor, determines that the distributor has the request permission, and then takes out the hash value which has not been modified by the parameters and has not been issued by the intelligent contract from the block chain for issuing; and marks this hash record as issued on the chain.
Optionally, before the receiver performs on-chain inspection on the digital information and the hash value, the distributor adds the on-chain identity of the receiver to the on-chain owner list of the hash value, so that the receiver obtains the authority to perform on-chain inspection on the digital information.
The receiver is granted the checking authority and the chain checking process of the digital information and the hash value can be directly completed through the intelligent contract, the distributor can also send the transaction to the corresponding intelligent contract through the centralized server to complete the granting of the checking authority of the receiver, and the receiver can also send the transaction completion chain verification to the corresponding intelligent contract through the centralized server.
Optionally, the chain checking the digital information and the hash value by the receiver further includes: and the receiving side submits the identity information and the hash value to the block chain, and the block chain returns all record information of the hash value according to the identity information and the hash value.
The receiving party can also submit the service information while submitting the identity information; the record information of the returned hash value may also include service information and related parameters.
Optionally, the receiver modifies a parameter of the hash value on the blockchain.
It should be noted that, according to the embodiment of the present invention, the batch digital information is generated in batch for the request of the distributor of the centralized server; or the distributors generate in batch and send the generated product to the centralized server.
The following takes the digital information as the activation code of the software product in the software sale as an example to further specifically describe the implementation process:
a manufacturer selling software, namely a distributor of digital information, generates a series of software activation codes in batch by requesting a centralized server; or the manufacturer generates the activation code by itself and sends the activation code to the centralized server.
After the centralized server performs hash processing on the software activation codes one by one, writing a hash value into a block chain through an intelligent contract;
in the process of selling the activation code, the manufacturer requests the centralized server to take out the activation code; after confirming that the manufacturer has the request distribution authority of the service, the centralized server takes out the hash value which has no modified parameters and has no record of issuing from the block chain through the intelligent contract; and marks this hash record as issued on the chain.
The centralized server finds out the software activation code corresponding to the taken hash value and sends the software activation code to a manufacturer;
the manufacturer sends the software activation code and the hash value to the product receiver.
The manufacturer needs to add the chain identity of the product receiver to the chain owner list of the hash value, so that the product receiver obtains the right to check the activation code.
And the product receiving side submits the identity information, the service information and the hash value to the block chain, and the block chain returns all record information of the hash value according to the identity information, the service information and the hash value.
The recipient may modify parameters of the hash value over the blockchain, such as recording and modifying the number of activations of the software product. This allows for more efficient recording and verification of products for which the software may be activated a limited number of times.
Through the technical scheme of the specification, chain is established in the batch generation and inspection processes of the digital information, and the content of the digital information cannot be tampered, so that the issuing process is more reliable, and counterfeiting and repentance cannot be performed. The method is particularly suitable for the distribution and authorization processes of digital products such as activation codes of software products.
