Description

Technical Field

[0001] The present invention relates to the cross - technical field of commodity quality inspection and judicial evidence preservation, and specifically provides a chain - type management system and evidence preservation method for randomly inspected physical evidence of commodities based on blockchain and judicial evidence preservation. Background Art

[0002] The randomly inspected physical evidence management system for commodities is a device used to manage the randomly inspected physical evidence of commodities.

[0003] The existing randomly inspected physical evidence management system for commodities still has deficiencies, specifically: the existing physical evidence management relies on physical sealing and paper records, resulting in evidence islands; the video evidence preservation platform is a separate platform, and cross - platform evidence preservation leads to difficulties in data association; manual entry of codes is prone to errors and the authenticity cannot be verified.

[0004] Therefore, a chain - type management system and evidence preservation method for randomly inspected physical evidence of commodities based on blockchain and judicial evidence preservation are needed to solve the problems raised in the above background art. Summary of the Invention

[0005] The purpose of the present invention is to provide a chain - type management system and evidence preservation method for randomly inspected physical evidence of commodities based on blockchain and judicial evidence preservation to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A chain - type management system for randomly inspected physical evidence of commodities based on blockchain and judicial evidence preservation includes an evidence preservation platform, and an evidence bag number pre - chain - entry module, a video evidence preservation and blockchain evidence preservation linkage engine, and an anti - mis - filling verification module are set in the evidence preservation platform.

[0008] As a preferred solution of the present invention, it includes the following steps:

[0009] S1. The administrator creates a random inspection task in the evidence preservation platform, enters the clear code of the evidence bag, and the evidence bag number pre - chain - entry module in the evidence preservation platform will automatically analyze the blockchain contract address in the hidden code, complete the number pre - chain - entry, and generate a pre - evidence preservation certificate with a time - space stamp.

[0010] S2. The random inspector logs in to the evidence preservation platform and enters the random inspection task, selects the "video evidence preservation" function, and the random inspector performs forced verification according to the requirements of the evidence preservation platform. After the verification is completed, video shooting starts.

[0011] S3. The shot video file is uploaded to the evidence preservation platform. The evidence preservation platform automatically names the video file and uploads the hash value of the video file to the chain. At the same time, the evidence preservation platform mirrors the video file data to the cloud evidence room of the notary office and generates a judicial evidence preservation report.

[0012] As a preferred embodiment of the present invention, a dual - zone anti - counterfeiting number is set on the physical evidence bag in S1. The dual - zone anti - counterfeiting number includes a visible code and a hidden code. The pre - stored evidence certificate in S1 includes the sampling task creation time, the sampling task execution location, the types of sampled physical evidence, the quantity of sampled physical evidence, and the hash value of the hidden code.

[0013] As a preferred embodiment of the present invention, the steps of forced verification in S2 are as follows: the sampler manually inputs the visible code on the physical evidence bag, and the evidence storage platform automatically compares the hidden - code hash value with the pre - stored evidence record. If the two are the same, the verification passes, and the sampler is prompted to start video shooting. If the two are different, the verification fails, and the evidence storage platform prompts the sampler to re - input the visible code.

[0014] As a preferred embodiment of the present invention, the requirements for video shooting in S2 are that the camera lens needs to continuously aim at the physical evidence bag number, and the physical evidence sealing process needs to be completely recorded by shooting.

[0015] As a preferred embodiment of the present invention, when shooting the video in S2, the video evidence storage enables GPS positioning watermarking to ensure spatial authenticity.

[0016] As a preferred embodiment of the present invention, the hidden code in the dual - zone anti - counterfeiting number is generated using the national cryptography SM3 algorithm and includes a blockchain address and a check code.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, the administrator creates a sampling inspection task in the evidence deposit platform and inputs the clear code of the physical evidence bag. The physical evidence bag number pre-chain module in the evidence deposit platform will automatically parse the blockchain contract address in the hidden code, complete the number pre-chain, and generate a pre-evidence deposit certificate with a time and space stamp. The sampler logs in to the evidence deposit platform and enters this sampling inspection task, selects the "video evidence deposit" function. The sampler performs a mandatory verification according to the requirements of the evidence deposit platform. After the verification is completed, video shooting begins. The captured video file is uploaded into the evidence deposit platform. The evidence deposit platform automatically names the video file and uploads the hash value of the video file to the blockchain. At the same time, the evidence deposit platform mirrors the video file data to the cloud evidence room of the notary office and generates a judicial evidence deposit report. The platform operation shortens the average evidence deposit time from 15 minutes to 4 minutes. In addition, by using the hidden code verification and anti-misfilling mechanism, the error rate of the physical evidence bag number entry approaches 0, forming an irreversible evidence chain from the physical number on the chain to the video process evidence deposit and then to the notary office synchronization. The physical evidence bag number on the chain, video evidence deposit, and notary office synchronization are all completed on a single platform, eliminating cross-platform data breakpoints. The physical evidence bag number serves as a globally unique identifier, and at the same time as the initial anchor point for blockchain evidence deposit and the naming rule for video evidence deposit files. The physical evidence bag adopts a dual-zone anti-counterfeiting number of clear code + hidden code, with strong anti-counterfeiting performance, solving the problems of the existing physical evidence management relying on physical sealing and paper records, resulting in evidence islands, the video evidence deposit platform being a separate platform, cross-platform evidence deposit leading to difficult data association, manual entry of codes being prone to errors, and being unable to verify authenticity.

[0025] For embodiments, please refer to Figure 1 , the present invention provides a technical solution:

[0026] A commodity sampling physical evidence chain management system based on blockchain and judicial evidence storage, including an evidence storage platform 1, in which an evidence bag number pre-chain module 2, a video evidence storage and blockchain evidence storage linkage engine 3, and an anti-misfilling verification module 4 are provided.

[0027] Furthermore, it includes the following steps:

[0028] S1. The administrator creates a sampling task in the evidence storage platform 1, inputs the clear code of the evidence bag, and the evidence bag number pre-chain module 2 in the evidence storage platform 1 will automatically parse the blockchain contract address in the hidden code, complete the number pre-chain, and generate a pre-evidence storage certificate with a time and space stamp.

[0029] S2. The sampler logs in to the evidence storage platform 1 and enters this sampling task, selects the "video evidence storage" function, and the sampler performs a mandatory verification according to the requirements of the evidence storage platform 1. After the verification is completed, video shooting starts.

[0030] S3. The shot video file is uploaded to the evidence storage platform 1. The evidence storage platform 1 automatically names the video file and uploads the hash value of the video file to the blockchain. At the same time, the evidence storage platform 1 mirrors the video file data to the cloud evidence room of the notary office and generates a judicial evidence storage report.

[0031] Furthermore, in S1, a dual-zone anti-counterfeiting number is set on the evidence bag. The dual-zone anti-counterfeiting number includes a clear code and a hidden code. The pre-evidence storage certificate in S1 includes the sampling task creation time, the sampling task execution location, the types of sampled physical evidence, the quantity of sampled physical evidence, and the hash value of the hidden code.

[0032] Further, the step of forced verification in S2 is that the sampling inspector manually inputs the clear code on the physical evidence bag, and the evidence storage platform 1 automatically compares the hidden code hash value with the pre-stored evidence record. If the two are the same, the verification passes, and the sampling inspector is prompted to start video shooting. If the two are different, the verification fails, and the evidence storage platform 1 prompts the sampling inspector to re-enter the clear code.

[0033] Further, the requirements for video shooting in S2 are that the camera lens needs to continuously aim at the physical evidence bag number, and the physical evidence sealing process needs to be completely recorded.

[0034] Further, when shooting the video in S2, the video evidence storage enables GPS positioning watermark to ensure spatial authenticity.

[0035] Further, the hidden code in the dual-zone anti-counterfeiting number is generated using the national secret SM3 algorithm and includes the blockchain address and the check code.

[0036] The working process of the present invention: When the commodity sampling physical evidence chain management system and evidence storage method based on blockchain and judicial evidence storage designed by this solution are in operation, the administrator creates a sampling task in the evidence storage platform 1 and inputs the clear code of the physical evidence bag. The physical evidence bag is set with a dual-zone anti-counterfeiting number, which includes a clear code and a hidden code. The hidden code in the dual-zone anti-counterfeiting number is generated using the national secret SM3 algorithm and includes the blockchain address and the check code. The physical evidence bag number pre-chain module 2 in the evidence storage platform 1 will automatically parse the blockchain contract address in the hidden code, complete the number pre-chain, and generate a pre-stored evidence certificate with a time and space stamp. The pre-stored evidence certificate includes the sampling task creation time, the sampling task execution location, the types of sampled physical evidence, the quantity of sampled physical evidence, and the hash value of the hidden code;

[0037] The sampling inspector logs in to the evidence storage platform 1 and enters this sampling task, selects the "video evidence storage" function. The sampling inspector performs forced verification according to the requirements of the evidence storage platform 1. The sampling inspector manually inputs the clear code on the physical evidence bag, and the evidence storage platform 1 automatically compares the hidden code hash value with the pre-stored evidence record. If the two are the same, the verification passes, and the sampling inspector is prompted to start video shooting. If the two are different, the verification fails, and the evidence storage platform 1 prompts the sampling inspector to re-enter the clear code. After the verification is completed, video shooting starts. When shooting the video, the sampling inspector needs to keep the video camera lens continuously aimed at the physical evidence bag number and the physical evidence sealing process needs to be completely recorded. At the same time, the video evidence storage enables GPS positioning watermark to ensure spatial authenticity;

[0038] S3, the shot video file is uploaded to the evidence storage platform 1. The evidence storage platform 1 automatically names the video file and uploads the hash value of the video file to the blockchain. At the same time, the evidence storage platform 1 mirrors the video file data to the cloud evidence room of the notary office and generates a judicial evidence storage report.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
