Problems solved by technology

However, the traditional digital evidence storage system usually provides storage services unilaterally by the storage system owner, which often faces the following risks: for example, the data has the risk of being tampered with, attacked, lost, etc., making it difficult to guarantee data security; and it is difficult to prove digital The ownership of assets, the verification process is cumbersome
In addition, because the data is provided unilaterally, the data has no legal effect and is not officially recognized

Embodiment 1

[0054] Please refer to figure 1 and figure 2 , this embodiment proposes a method for creating digital certificates, which can be applied to online digital certificates for important digital assets such as contracts, bills, and media information with copyright attributes, and can effectively ensure the authenticity and integrity of digital assets , timeliness and traceability, etc.

[0055] The method for creating the digital deposit certificate will be described in detail below.

[0056] S110. Perform data preprocessing on the object to be deposited to obtain corresponding source data for the certificate and extract file meta-information of the object to be deposited.

[0057] In this embodiment, the data preprocessing mainly includes two steps, one is to verify the data integrity and legitimacy of the object to be deposited; The data will be used to be stored in the blockchain together with the subsequently generated unique digital certificate of deposit.

[0058] Exempl...

Embodiment 2

[0087] Please refer to Figure 6 , this embodiment proposes a digital certificate storage verification method, which can be applied to the digital certificate storage certificate obtained based on the method in the above-mentioned embodiment 1 to carry out certificate storage verification. Exemplarily, the digital certificate verification method includes:

[0088] S310. Receive a unique certificate identifier of the digital certificate certificate to be verified. Wherein, the unique certificate deposit identifier may be a certificate ID, or a digital certificate deposit fingerprint or the like.

[0089] S320, query whether there is a block with the same certificate identifier in the blockchain according to the unique certificate identifier. If there is a block with the same certificate identifier, go to step S330, otherwise go to step S340.

[0090] S330, if it exists, determine that the specific digital certificate exists.

[0091] S340, if it does not exist, it is judged...

Embodiment 3

[0096] Please refer to Figure 7 , based on the methods of the above-mentioned embodiments 1 and 2, this embodiment proposes a digital certificate storage system 100, the digital certificate storage system 100 mainly includes two parts, which are the part for creating digital certificates and the created digital certificate system. The part of the digital certificate for verification.

[0097] Exemplarily, the digital certificate system 100 includes a digital certificate creation module 10 and a digital certificate verification module 20. The digital certificate creation module 10 is mainly used to perform data preprocessing on the object to be deposited to obtain the corresponding certificate source Data and extract the file meta-information of the object to be stored; calculate the digital fingerprint of the object to be stored through the hash algorithm, and sign the digital fingerprint to obtain the digital signature of the object to be stored; based on the file meta-infor...

Abstract

The embodiment of the invention provides a digital evidence storage creation method, a digital evidence storage verification method and a digital evidence storage system. The method comprises the steps: carrying out the data preprocessing of a to-be-stored object, so as to obtain the corresponding evidence storage source data, and extracting the file meta-information of the to-be-stored object; calculating a digital evidence storage fingerprint of the to-be-stored object, and signing the digital evidence storage fingerprint to obtain a digital signature of the to-be-stored object; generating a digital certificate with a unique certificate ID of the to-be-stored object based on the file meta-information, the digital certificate fingerprint and the digital signature; and storing the evidence storage source data and the digital evidence storage certificate as transaction blocks in the block chain. According to the technical scheme, credible digital evidence storage is carried out based on the electronic signature technology, the block chain technology and the like, and authenticity, integrity, timeliness, traceability and the like of digital assets and the like are ensured.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a digital certificate creation method, a digital certificate verification method and a digital certificate system. Background technique [0002] More and more digital assets (such as contracts, bills, copyright creations, etc.) need to be stored in an online digital evidence storage system for publicity, supervision, and ownership declaration of digital assets. However, the traditional digital evidence storage system usually provides storage services unilaterally by the storage system owner, which often faces the following risks: for example, the data has the risk of being tampered with, attacked, lost, etc., making it difficult to guarantee data security; and it is difficult to prove digital The ownership of assets, the verification process is cumbersome. In addition, since the data is provided unilaterally, the data has no legal effect and is not officially recognized. T...
