After the time stamp information is written, as shown in fig. 2, in this embodiment, the information record block chain mechanism sends a time stamp recording receipt to the third-party certification authority, where the time stamp recording receipt includes a block number and a block hash value of the time stamp block. After receiving the time stamp block recording receipt, the third-party certification authority inquires the block chain, confirms the existence of the block contained in the recording receipt and compares the block hash value. And confirming whether the time stamp information and the signature in the block are consistent with those sent by the user. The data of other certification authorities are also verified together. In this embodiment, the time stamp is verified to ensure that the time stamp is written to the block chain, rather than being withheld by the information record block chain mechanism and intended for future use. After the verification is passed, the third-party certification authority stores the time stamp block to the local as a basis for comparison with the block chain system at a later date.
In one embodiment, after sending the time stamp receipt to the third party certification authority, the docketing method further comprises:

And after the information recording block chain mechanism receives the time stamp confirmation information, verifying the time stamp confirmation information and writing the time stamp confirmation information into the time stamp confirmation block. The number of the certification authorities confirming the validity needs to exceed a preset specified ratio, otherwise, the time stamp confirmation block is invalid. That is, in the embodiment, under the condition that the number of the third-party certification authorities is fixed, after the third-party certification authority verifies that the time stamp writing confirmation succeeds, the time stamp confirmation information is sent to the information recording block chain mechanism. The information filing mechanism determines that the current time stamp confirmation information is valid only when the time stamp confirmation information of more than a certain number of third-party certification mechanisms is received, otherwise, the current time stamp confirmation information is invalid.
In the case that the number of the valid third-party certification authorities is confirmed to satisfy the condition, the information record block chain mechanism writes the time stamp confirmation information into the time stamp confirmation block, for example, the content in the time stamp confirmation block may include: time stamp written blockchain confirmation information provided by a third party certification authority for ensuring that a time stamp has been written to a blockchain, mainly comprising: the authentication authority name, the time stamp block number, the time stamp block hash value, the confirmation time, and a digital signature (used for verifying whether the time stamp information confirmation information is provided by the authentication authority) obtained by encrypting the above contents by a private key. And then associating the time stamp confirming block with the corresponding time stamp block.
In an embodiment, after associating the time stamp confirmation block with the corresponding time stamp block, the filing method further includes:
sending a time stamp receiving and recording confirmation receipt to the third party certification authority, wherein the time stamp receiving and recording confirmation receipt contains second identification information of the time stamp confirmation block;
and the time stamp receiving and recording confirmation receipt is used for verifying the time stamp confirmation information by a third party certification authority according to the second identification information.
As shown in fig. 2, after the information record block chain mechanism writes the time stamp acknowledgement information into the time stamp acknowledgement block, the time stamp acknowledgement receipt is sent to the third party certification mechanism, where the time stamp acknowledgement receipt includes second identification information of the time stamp acknowledgement block, and the second identification information may be a block number and a block hash value of the time stamp acknowledgement block. After receiving the time stamp confirmation receiving receipt, the third party certification authority inquires the block chain, confirms the existence of the block contained in the receiving receipt and compares the block hash value. And confirming whether the time stamp confirmation information and the signature in the block are consistent with those sent by the user. The data of other certification authorities may also be verified. The third party certification authority may save the confirmation block locally upon passing the check as a basis for later comparison with the blockchain system. If data verification is problematic, the third party certification authority may issue a denial statement to the information docket blockchain authority.
In one embodiment, the filing method further comprises:
and sending an information registration confirmation notice to the user, wherein the information registration confirmation notice contains the associated data of the record information.
As shown in fig. 2, after the information record blockchain mechanism and the third-party certification mechanism complete confirmation, the information record blockchain mechanism may send an information registration confirmation notification to the user, where the information registration confirmation notification includes associated data of the record information, such as a timestamp block number and a timestamp confirmation block number. After receiving the information registration confirmation notice, the user inquires the block chain, downloads and stores the corresponding time stamp block and the time stamp confirmation block to the local as one of the retention evidences.
As shown in fig. 3, in the embodiment, the record information blocks may be arranged according to the information registration sequence, the time stamp block and the time stamp confirmation block appear periodically, and the authentication date of the record information recorded in each record information block is the authentication date recorded in the most recent time stamp block.
The user can reserve the filing information block, the time stamp block and the time stamp confirmation block, and the third-party certification authority can reserve the time stamp block and the time stamp confirmation block. The block chain objectively records the filing sequence and the filing time of the filing information. The information-deposited blockchain mechanism also cannot modify historical blocks because modifying any block of the blockchain requires rebuilding all blocks behind it. Since each block in the block chain records the hash value of the previous block, and the hash value of the reconstructed block changes, the next block needs to be updated, and so on. As mentioned above, the third party certification authority, the user, also retains a copy of the blocks locally. Once block reconstruction occurs, it may happen that the reconstructed block is inconsistent with the block retained by the third party certification authority. Therefore, the recording method of the embodiment can monitor the block chain and prevent malicious tampering. According to the invention, a third-party certification mechanism is introduced to supervise the information backup block chain, so that the risk of trust centralization is reduced, and meanwhile, the operation and maintenance cost of data consistency maintenance is greatly reduced.
An embodiment of the present invention further provides a device for filing, including:
the sending module is used for sending a time stamp request to a third-party certification authority according to a preset time interval after the recording is carried out according to the recording information of the user;
the receiving module is used for receiving the time stamp information sent by the third-party certification authority;
and the data processing module is used for detecting the validity of the time stamp information and writing the time stamp information into a corresponding time stamp block under the condition that the time stamp information is determined to be valid.
The embodiment of the present invention also provides a computer-readable storage medium, on which a computer program is stored, and the computer program, when executed by a processor, implements the steps of the aforementioned filing method.
