Based on the information notarization system shown in fig. 1, the embodiment of the invention provides a blockchain-based information notarization method, as shown in fig. 2, comprising the following steps:
and step 101, the request terminal sends the information to be notarized to the management platform.
The information to be notarized may be any information to be notarized, such as patent information, copyright information, and the like.
After receiving the information to be notarized, the management platform can store the information to be notarized. And then, sending the indication information of the information to be notarized to a blockchain platform. For example, the management platform may establish a connection with any node in the blockchain platform, and the management platform may send the indication information to that node. After receiving the indication information, the node can broadcast the indication information to other nodes in the blockchain platform, so that all nodes in the blockchain platform store the indication information.
And 103, the notarization terminal acquires the information to be notarized based on the indication information of the information to be notarized in the blockchain platform.
The notarization terminal may be connected to any node in the blockchain platform and may be capable of acquiring the above-mentioned indication information stored in the node. And then, the notarization terminal can acquire the information to be notarized according to the indication information.
After the notarization terminal acquires the information to be notarized, a user of the notarization terminal can audit the authenticity of the information to be notarized, and notarization results of the information to be notarized are input into the notarization terminal. The notarization result is used for indicating whether the information to be notarized is real.
After the notarization terminal obtains the notarization result, the notarization result can be sent to any node in the blockchain platform. After receiving the notarization result, the any node can broadcast the notarization result to other nodes in the blockchain platform, and at the moment, each node in the blockchain platform stores the indication information of the information to be notarized and the notarization result.
And 106, the management platform acquires a notarization result in the blockchain platform.
And step 107, the management platform sends the notarization result to the request terminal.
In summary, in the information notarization method provided by the embodiment of the invention, the request terminal and the notarization terminal can perform on-line notarization of information through the management server and the blockchain platform. Therefore, the user of the request terminal does not need to conduct notarization transaction to the notarization department, and the flow and efficiency of notarization transaction are greatly reduced.
Based on the information notarization system shown in fig. 1, another information notarization method based on block chain is provided in the embodiment of the present invention, as shown in fig. 3, the method includes:
The notarization request carries user information of the request terminal and the type of information to be notarized.
The user of the requesting terminal may log into the management platform in the requesting terminal, after which the user of the requesting terminal may input (or set) information of the user and the type of information to be notarized to the requesting terminal. The type of the information to be notarized can be any type of patent information, copyright information, household registration information and the like. After the user inputs the information on the request terminal, the user can also operate on the request terminal so that the request terminal sends a notarization request carrying the information to the management platform.
And 202, the management platform sends a resource transfer instruction to the request terminal based on the notarization request.
The resource transfer indication indicates a transfer of a target amount of resources to the management platform.
After receiving the notarization request, the management platform may send a resource transfer instruction to the request terminal, where the resource transfer instruction is used to instruct to transfer the target amount of resources to the management platform. It may be considered that the resource transfer indication is used to indicate terminal payment for facilitating subsequent transaction of the notary event.
After receiving the resource transfer instruction, the requesting terminal can transfer the target amount of resources to the management platform based on the resource transfer instruction. It should be noted that, the request terminal may directly transfer the resource to the management platform, or may, of course, transfer the resource to the management platform through the third party device, where the resource transfer instruction also carries the address of the third party device.
After the request terminal transfers the target amount of resources to the management platform, the management platform determines that the request terminal pays successfully, and at this time, the management platform can generate a notary item identifier, a first private key and a first public key of information to be notary for the notary item.
The notarization item identifier is used for indicating the notarization item which is transacted by the user of the request terminal. The first private key is used for encrypting information to be notarized, and the first public key can decrypt the information encrypted by the first private key. The first private key is not disclosed, only the management platform owns the first private key, but the first public key is disclosed, and any device in the whole information notarization system can acquire the first public key.
The information to be notarized may be any information to be notarized, such as patent information, copyright information, and the like.
The management platform can perform hash calculation on the information to be notarized to obtain a hash value of the information to be notarized. It should be noted that the hash values of different information are different, so the information to be notarized can be identified by the hash values.
After obtaining the hash value of the information to be notarized, the management platform may encrypt the hash value by using the first private key obtained in step 204, so as to obtain first encrypted information.
And step 208, the management platform stores the information to be notarized to the storage platform.
After the management platform acquires the information to be notarized, the information to be notarized can be uploaded to the storage platform to store the information to be notarized. For example, the storage platform may include a plurality of servers, where the management server may first segment the information to be notarized, and then upload the segmented information to be notarized to some or all servers in the plurality of servers, so as to implement distributed storage of the information to be notarized.
The indication information comprises first encryption information, a notary item identifier, user information of the request terminal and the type of information to be notary.
Step 209 may refer to step 102, and the embodiments of the present invention are not described herein.
In addition, the indication information can be understood as first encryption information, user information and types of information to be notarized corresponding to the notarized item identification. After uploading the indication information to the blockchain platform, the notarization terminal can conveniently acquire the types of the first encryption information, the user information and the to-be-notarized information corresponding to each notarized item identifier by taking the notarized item identifier as a unit, and further transacting the notarized item based on the information.
It should be noted that, in the embodiment of the present invention, the hash value is encrypted, so that the security of the hash value and the security of the document to be notarized corresponding to the hash value can be ensured.
Step 210, the notarization terminal obtains the indication information of the information to be notarized in the blockchain platform.
The type in the indication information belongs to at least one information type corresponding to the notarized terminal.
After acquiring the indication information, the notarized terminal may acquire the first public key generated by the management platform in step 204, so as to decrypt the first encrypted information encrypted by the first private key based on the first public key in step 212.
And 212, decrypting the first encrypted information by the notarization terminal based on the first public key to obtain a hash value of the information to be notarized.
And 213, the notarization terminal acquires the information to be notarized from the storage platform based on the hash value of the information to be notarized.
After obtaining the hash value of the information to be notarized, the notarized terminal can obtain the information to be notarized stored in the storage platform based on the hash value. For example, if the management platform segments the information to be notarized when storing the information to be notarized, the notarized information needs to be recombined when the notarized terminal obtains the information to be notarized, so as to obtain the information to be notarized.
After the notarization terminal acquires the information to be notarized, a user of the notarization terminal can audit the information to be notarized on the notarization terminal so as to determine the authenticity of the information to be notarized. Then, the user of the notarization terminal can input the notarization of the information to be notarized on the notarization terminal. It should be noted that, when the information to be notarized is truly information, the user of the notarized terminal needs to input the notarized certificate on the notarized terminal; when the information to be notarized is not real information, the user of the notarized terminal does not need to input the notarized on the notarized terminal.
And 215, encrypting the public certificate by the notarization terminal based on a second private key of the notarization terminal to obtain a notarization result of the information to be notarized.
The public certificate terminal is provided with a second private key used for encrypting the public certificate and a second public key corresponding to the second private key. The second private key is not disclosed, and only the notarized terminal holds. The second public key is disclosed, and each device in the information notarization system can acquire the second public key.
After the public certificate of the information to be authenticated is obtained, the public certificate can be encrypted by using the second private key, for example, the public certificate is signed by using the second private key, so that a public certificate result with the public certificate information is obtained. And the confidentiality of the public certificate can be ensured by encrypting the public certificate, so that illegal use of the public certificate after an illegal molecule obtains the public certificate is prevented.
Step 216 may refer to step 105, and embodiments of the present invention are not described herein.
And step 218, the management platform sends the notarization result to the request terminal.
And 220, the request terminal decrypts the notarization result based on the second public key to obtain the public certificate.
After receiving the public certificate result of the information to be public-certified, the request terminal can decrypt the public certificate result encrypted by the second private key based on the second public key to obtain the public certificate. The request terminal obtains the public certificate of the information to be notarized, and the whole flow is seen to be carried out on line, so that the user of the request terminal does not need to carry out off-line notarization transaction to a notarization department (such as the place where the notarization terminal is located).
In summary, in the information notarization method provided by the embodiment of the invention, the request terminal and the notarization terminal can perform on-line notarization of information through the management server and the blockchain platform. Therefore, the user of the request terminal does not need to conduct notarization transaction to the notarization department, and the flow and efficiency of notarization transaction are greatly reduced.
And the indication information of the information to be notarized and the notarized result are stored in the blockchain platform, and the accuracy of the indication information and the notarized result can be ensured because the information in the blockchain platform cannot be tampered.
