Detailed Description
In the existing electronic document certification method, as shown in fig. 1, a single certification and a single verification are performed on an electronic document. Specifically, assuming that the user wants to document more than one electronic file, the electronic file needs to be uploaded to the document service device separately for each electronic file, the document service device encapsulates the hash value of the electronic file into a document transaction and submits the document transaction to the blockchain network, and the document transaction is finally written into the blockchain by the blockchain network, which means that the electronic file is anchored in the blockchain, so that the document is document stored. And if the verification is required to be carried out on a certain electronic file, positioning an anchor point of the electronic file in the blockchain according to the hash value of the electronic file (namely, the verification transaction containing the hash value of the electronic file), and if the anchor point exists, confirming that the verification is passed.
In the embodiment of the present disclosure, as shown in fig. 2, batch verification and single verification are performed on the electronic files, so that the efficiency of verifying the electronic files can be improved on the premise that verification of the single electronic file is not affected.
In order for those skilled in the art to better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail below with reference to the drawings in the embodiments of the present specification, and it is apparent that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification shall fall within the scope of protection.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
Fig. 3 is a flow chart of a method for storing and verifying an electronic file according to an embodiment of the present disclosure, including the following steps:
s300: and acquiring at least two electronic files to be authenticated.
The execution subject of the method is a certification service device of a data certification service provider, which can be a server of the data certification service provider. And the evidence storage service equipment is provided with a blockchain program for carrying out data interaction with the blockchain network so as to realize the butt joint of the evidence storage service equipment and the blockchain network.
The electronic files described herein are files that are generated in digital devices and environments, stored in carriers such as magnetic tapes, magnetic discs, optical discs, etc., and read, processed, and transferred over a communication network by devices such as computers. For example, in the context of web page evidence, the electronic file to be stored may be a web page screenshot file or a video file recording the process of evidence web page.
S302: and executing hash calculation according to the at least two electronic files to obtain a certification hash value.
As an optional implementation manner, in step S302, the at least two electronic files may be packaged into a file package, and a hash algorithm is performed with the file package as an object, to obtain a verification hash value.
As another optional implementation manner, in step S300, the certificate service device may specifically obtain a file compression packet (for example, may be in a zip format or may be in an rar format), where the file compression packet is obtained after compressing at least two electronic files to be authenticated. In step S302, a hash calculation is performed with the file compression packet as an object, to obtain a verified hash value.
Further, in step S300, at least two electronic files to be authenticated uploaded by the user may be received, and compression processing is performed on the at least two electronic files to obtain a file compression package. The file compression package uploaded by the user can also be received.
Further, as another alternative embodiment, in step S302, a merck tree may be constructed based on the hash value of each of the at least two electronic files to be authenticated; and determining the root hash value of the merck tree as a evidence hash value.
S304: and constructing a forensic transaction containing the forensic hash value, and submitting the forensic transaction to the blockchain network.
In the embodiment of the specification, the certificate hash value obtained based on at least two electronic files to be authenticated is written into the certificate transaction, and the certificate transaction is submitted to the blockchain network, so that the blockchain network writes the certificate transaction into the blockchain. Therefore, more than one electronic file can be anchored into the blockchain in batches through one transaction submitting operation, and the verification efficiency of the electronic file is improved.
S306: and recording the corresponding relation between each electronic file and the certification hash value.
In the present embodiment, the anchors of the at least two electronic files in the blockchain are identical (i.e., anchored to the same certification transaction), however, the certification transaction encapsulates not the hash value of the single electronic file, but one certification hash value derived from the at least two electronic files.
In practical applications, a user often needs to check the certificate of a single electronic file, and typically submits the single electronic file to a certificate authority to request checking. For the certification service set, the anchor point of the electronic file cannot be located in the blockchain only according to the electronic file.
Therefore, the forensic service apparatus needs to record which electronic files corresponding to each forensic hash value written in the blockchain are. In this way, the certification service device can map a certain electronic file to be verified to a corresponding certification hash value, so as to determine the certification transaction containing the certification hash value as an anchor point of the electronic file in the blockchain.
In addition, in the embodiment of the present specification, the execution timing of step S306 is not particularly limited. For example, step S306 may be performed before step S302 is performed, step S302 is performed simultaneously, or step S302 is performed thereafter.
Further, in step S306, for each electronic file, a hash calculation may be performed with the electronic file as an object, to obtain a hash value of the electronic file; then, the corresponding relation between the hash value of each electronic file and the stored hash value is recorded.
Fig. 4 is a flowchart of a method for verifying a certificate of an electronic file according to an embodiment of the present disclosure, including the following steps:
s400: and receiving a certification verification request sent by the user.
The method shown in fig. 4 is performed by a certification service set.
The certification verification request is issued when a user needs to perform certification verification (i.e., verify whether a certification has been already stored) on an electronic file to be certified (referred to herein as a target electronic file) that has been uploaded to a certification service device before the user. And the certification verification request carries the target electronic file.
S402: and judging whether a stored hash value corresponding to the hash value of the target electronic file exists or not according to the corresponding relation recorded in the method shown in fig. 3.
S404: if so, checking whether the proving transaction containing the proving hash value is written into the blockchain through the blockchain network, and feeding back a checking result to the user.
As described above, the certification service apparatus records, for each certification transaction written in the blockchain, each electronic file (or a hash value of an electronic file) corresponding to a certification hash value included in the certification transaction. Therefore, if the stored-certificate hash value corresponding to the target electronic file exists, the stored-certificate service equipment judges whether the stored-certificate hash value is written into the blockchain through the blockchain network, if so, the stored-certificate of the target electronic file is indicated, and if not, the stored-certificate of the target electronic file is indicated.
Further, if the forensic hash value corresponding to the target electronic file does not exist, the forensic service device may reject the forensic verification request.
By the method shown in fig. 3 and fig. 4, on one hand, the certificate service device encapsulates the certificate hash value obtained based on at least two electronic files to be authenticated into one certificate transaction, and submits the certificate transaction to the blockchain network once, so that more than one electronic file can be anchored in the blockchain through one transaction submitting operation; on the other hand, the certification service equipment records the corresponding relation between each electronic file in the at least two electronic files and the certification hash value, so that the record of which certification transaction in the blockchain each electronic file is specifically anchored in is equivalent to that, and the certification verification of a single electronic file is not influenced. According to the embodiment of the specification, the efficiency of verifying the electronic file can be improved on the premise that verification of the electronic file is not affected.
