All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the problems that the retrieval efficiency is low, a plurality of block information needs to be stored by an individual (or an organization) in a judicial alliance chain, so that evidence is easy to lose, and a plurality of inconveniences are brought to a compact litigation process, the evidence processing method, the evidence processing device and the electronic equipment based on the alliance chain are provided by the embodiment of the invention.
For the convenience of understanding the embodiment, a method for processing evidence based on a federation chain disclosed in the embodiment of the present invention is first described in detail.
The embodiment of the invention provides an evidence processing method based on a alliance chain, which can be executed by electronic equipment with data processing capacity. Referring to fig. 1, a schematic flow chart of an evidence processing method based on a federation chain mainly includes the following steps S102 to S110:
step S102, when receiving a certificate storing request uploaded by a certificate storing holder, establishing a current block in a alliance chain; the evidence storing request comprises evidence holder information and evidence information.
The depositor may be an individual or an organization, the depositor information may be, but is not limited to, an Identity document (Identity ID), and the proof information may include, but is not limited to, information such as a bill form, a contract document, and the like.
Step S104, storing the information of the evidence holder and the evidence information in the current block in an encrypted manner.
After the evidence holder information and the evidence information pass the validity verification, the evidence holder information and the evidence information are linked and further encrypted and stored in the newly created block. The specific way of encrypted storage may refer to the related art, and is not described herein.
Step S106, generating an initial key value of the current block according to the information of the evidence holder and the evidence information.
The specific way of generating the initial key may refer to the related art, and is not described herein.
Step S108, based on the initial key value, a key of a first block matching the current block is obtained from a block located before the current block in the federation chain, where the first block is a block closest to the current block and having a same depositor as the depositor of the current block.
In step S110, the key of the first block and the initial key value are recorded in the current block as the key of the current block.
Thus, the process of storing the certificate is completed.
By applying the evidence processing method based on the alliance chain, when the evidence holder stores the evidence, the newly generated blocks can record the keys of all the blocks of the evidence holder during the previous evidence storage, so that all the related blocks of the same evidence holder are associated, the evidence holder does not need to download the whole alliance chain, all the blocks related to the evidence holder can be quickly inquired by only providing the key recorded during the latest evidence storage, the retrieval efficiency is high, and the evidence can be conveniently stored and retrieved.
Considering that there is no first block matching with the current block when the cardholder uploads the credential request for the first time, in this embodiment, before executing step S108, it is determined whether the credential request is the first upload of the cardholder; when the determination result is that the credential storage request is not the first upload by the credential storage holder, step S108 is executed, and when the determination result is that the credential storage request is the first upload by the credential storage holder, the initial key value is directly recorded in the current block as the key of the current block. Thus, the evidence storage efficiency is improved.
In some possible embodiments, it may be determined whether the credential request was first uploaded by the credential holder by: checking whether the certificate storing request carries a first uploading identifier or not; and when the certificate storing request does not carry the first uploading identification, determining that the certificate storing request is not the first uploading of the certificate storing holder, and otherwise, when the certificate storing request carries the first uploading identification, determining that the certificate storing request is the first uploading of the certificate storing holder. The first upload identifier may be added to the certificate storing request by checking a first upload icon on the page before the user uploads the certificate storing request. The judgment method is simple and quick.
In some possible embodiments, the step S108 may be implemented by: according to the initial key value, sequentially decoding and verifying the blocks positioned in front of the current block in the alliance chain according to the sequence from near to far of the distance from the current block, and determining the blocks passing the first verification as first blocks; a key for the first block is obtained.
Since the key of each block is related to the depositor information, there is a certain similarity between the keys of the blocks related to the same depositor. In this embodiment, a previous block (i.e., a block located before the current block in the federation chain) is subjected to traversal decoding operation by using the initial key value of the current block, and when the similarity between the key traversed to one block and the initial key value of the current block is matched or the same, the block passes verification, is the first block, and is not traversed any more.
Further, the method further comprises an evidence retrieval process, wherein the evidence retrieval process specifically comprises the following steps: acquiring an evidence retrieval request to determine a target key to be retrieved, wherein the target key comprises at least one key value, namely the target key can be a key string consisting of at least one key value; according to the target key, searching a target number of second blocks from the alliance chain (obtaining the address of each second block); wherein the number of targets is equal to the number of key values in the target key; and acquiring the evidence information stored in each second block according to the address of each second block, and determining the evidence information stored in each second block as target evidence information corresponding to the evidence retrieval request.
In some possible embodiments, the second tile may be retrieved by: and according to the target key, sequentially decoding and verifying each block in the alliance chain from near to far according to the distance from the newly created block in the alliance chain until the number of the second blocks passing the verification is equal to the number of the key values in the target key.
In the evidence processing method based on the alliance chain provided by the embodiment of the invention, after a person or an organization submits a evidence storing request to the alliance chain, a block is created to encrypt and store the information of a evidence holder and the evidence information, and the information of the evidence holder and the evidence information are integrated and encrypted to generate a KEY value (initial KEY value); the blocks all comprise a detection bit, the detection bit carries out decoding verification on the front block, records the KEY (KEY) of the front block passing the first verification, integrates the KEY with the KEY value of the current block and updates the KEY of the current block; when evidence retrieval is required, the evidence holder only needs to provide the KEY to verify the KEY, obtain the block address, and retrieve all blocks in the alliance chain through the address so as to achieve the purpose of quick retrieval.
For convenience of understanding, an embodiment of the present invention further provides another evidence processing method based on a federation chain, and as shown in fig. 2, the method includes:
when the certificate is stored, step S202 to step S206 are executed.
In step S202, an individual (or institution) provides electronic evidence to a judicial authority. The electronic evidence includes evidence holder information and evidence information.
In step S204, the judicial organization encrypts and chains the electronic evidence and stores the electronic evidence into the current block created in the alliance chain.
In step S206, the current block generates a KEY value, the previous block is decoded and verified by the detection bit, and the KEY value of the previous block passing the first verification and the KEY value generated by the current block are recorded in the current block at the same time.
The certificate can be stored for a plurality of times through the steps S202 to S206, and the process from the step S202 to S206 is completed in the non-retrieval stage.
When litigation occurs, the search stage is started, and steps S208 to S210 are executed.
In step S208, the individual (or institution) provides the current KEY to the judicial authority.
In step S210, the judicial organization finds all the evidence storage blocks belonging to the same person (or institution) in the alliance chain by the provided KEY.
For ease of understanding, the above method is also exemplarily described with reference to fig. 3 to 6, which are as follows:
(1) the individual submits information such as identity ID, bill form, contract document and the like to institutions such as courtroom, court and notary, CA/RA, judicial certification center and the like to verify the validity of the electronic evidence, and links the electronic evidence and the alliance chain to create a KEY for the electronic evidence, wherein the KEY is generated by a Block # 51655 and a Block #1365 shown in FIG. 3.
(2) As shown in fig. 4, the detection bit in Block #1365 performs decoding verification on the previous Block, and since the electronic proof is uploaded for the first time by the individual and there is no verified Block in the previous Block, the KEY generated by Block #1365 is recorded in Block # 1365.
(3) As shown in fig. 5, when the individual submits the electronic proof to the court again, a Block # 112251 is created again according to the step (1), and the current Block # 112251 generates a KEY 1; the current Block is decoded and authenticated according to the step (2) for the previous Block, and KEY is obtained when Block # 51655 succeeds, KEY is recorded, and KEY1 are jointly recorded in the current Block # 112251.
(4) As shown in fig. 6, after a period of time, the individual already has n blocks in the federation chain, and the individual and the court simultaneously hold a string of KEY values, and when a litigation requirement arises, the individual can quickly retrieve all the evidence-holding blocks by performing iterative verification in the federation chain based on the string of KEY values.

and when the judgment result shows that the storage request is not uploaded for the first time by the storage holder, executing the step of acquiring the key of the first block matched with the current block from the block positioned before the current block in the alliance chain based on the initial key value.
3. A federation chain-based evidence processing method as claimed in claim 2, wherein said determining whether the evidence-holding request is the first upload by the evidence-holding holder comprises:
checking whether the certificate storing request carries a first uploading identifier or not;
and when the certificate storing request does not carry a first uploading identifier, determining that the certificate storing request is not the first uploading of the certificate storing holder.
4. A federation chain-based evidence processing method as claimed in claim 2, wherein the method further comprises:
and when the judgment result is that the storage request is uploaded by the storage holder for the first time, recording the initial key value serving as the key of the current block in the current block.
5. A federation chain-based evidence processing method as claimed in claim 1, wherein said deriving a key of a first block matching the current block from a block preceding the current block in the federation chain based on the initial key value comprises:
according to the initial key value, sequentially decoding and verifying the blocks positioned in front of the current block in the alliance chain according to the sequence from near to far of the distance from the current block, and determining the blocks passing the first verification as first blocks;
a key for the first block is obtained.
6. A federation chain-based evidence processing method as claimed in claim 1, wherein after recording the key of the first chunk and the initial key value as the key of the current chunk in the current chunk, the method further comprises:
acquiring an evidence retrieval request to determine a target key to be retrieved, wherein the target key comprises at least one key value;
retrieving a target number of second blocks from the federation chain based on the target key; wherein the target number is equal to a number of key values in the target key;
and determining the evidence information stored in each second block as target evidence information corresponding to the evidence retrieval request.
7. A federation chain-based evidence processing method as claimed in claim 6, wherein said retrieving a target number of second blocks from the federation chain in dependence on the target key comprises:
and according to the target key, sequentially decoding and verifying each block in the alliance chain according to the sequence from near to far of the distance from the newly created block in the alliance chain until the number of second blocks passing verification is equal to the number of key values in the target key.
8. An evidence processing apparatus based on a federation chain, comprising:
the creation module is used for creating a current block in a alliance chain when a certificate storage request uploaded by a certificate storage holder is received; wherein the evidence storing request comprises evidence holder information and evidence information;
the storage module is used for encrypting and storing the evidence holder information and the evidence information in the current block;
a generating module, configured to generate an initial key value of the current block according to the information of the depositor and the evidence information;
an obtaining module, configured to obtain, based on the initial key value, a key of a first block that matches the current block from blocks in the federation chain that are located before the current block, where the first block is a block that is closest to the current block and has a same depositor as a depositor of the current block;
a recording module, configured to record the key of the first chunk and the initial key value as the key of the current chunk in the current chunk.
9. An electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the method of any one of claims 1-7 when executing the computer program.
10. A computer-readable storage medium, having stored thereon a computer program, characterized in that the computer program, when being executed by a processor, is adapted to carry out the method of any one of claims 1-7.
