Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of enterprise data exchange, in particular to a method and system for trusted exchange of enterprise data on a supply chain. BACKGROUND

[0002] Enterprise data exchange on a supply chain is an important part of supply chain management, which involves data flow between various links in the supply chain, such as suppliers, manufacturers, distributors, retailers, and end users.

[0003] The forms of enterprise data exchange on a supply chain mainly include electronic data exchange, application programming interface, cloud computing platform, and blockchain technology. The risk of enterprise data exchange on a supply chain is data theft by competitors. The above data theft is mainly based on network camouflage tools and network sniffing tools to achieve illegal data acquisition. Currently, data security on servers is mainly based on the firewall of the computer itself, which cannot identify fraudulent communication behavior based on special settings of the target enterprise server, and there is a risk of data being fraudulently obtained.

[0004] Therefore, it is urgent to design a method and related system hardware for trusted exchange of enterprise data on a supply chain to improve the security of enterprise data exchange on a supply chain. SUMMARY

[0005] To solve the above technical problems, the present application provides a method and system for trusted exchange of enterprise data on a supply chain. The technical scheme is as follows: A method for trusted exchange of enterprise data on a supply chain, comprising the following steps: Step 1: setting a trusted interaction verification module on the data terminal of each enterprise on the supply chain, and numbering a plurality of trusted interaction verification modules; setting a data transfer server; Step 2: the data interaction request enterprise server sends a data interaction request to the data transfer server, and the data transfer server forwards the data interaction request to the trusted interaction verification module of the specified data interaction target enterprise server; the corresponding numbered trusted interaction verification module performs a data trusted exchange multi-party verification mechanism to verify the legality and security of the data interaction request; The trusted exchange multi-party verification mechanism randomly generates at least three trusted interaction verification module numbers of cross-verification parties based on a random number algorithm, and cross-verifies the data interaction request to the numbered trusted interaction verification module; the numbered trusted interaction verification module verifies the legality and security of the data interaction request enterprise server based on the network address communication interaction cipher text of the data interaction request; Step 3, if the data interaction request in step 2 passes the trusted exchange multi-party verification mechanism, the trusted interaction verification module of the data interaction target enterprise server aggregates the data corresponding to the data interaction request, takes the highest security level in the aggregated data as the security level of the interaction data, and forms an interaction data packet based on the data interaction request and the security level label; Step 4, the trusted interaction verification module of the data interaction target enterprise server sends the interaction data packet to the data transfer server, the transfer server extracts the security level of the security level label, and if it is determined that the security level is greater than or equal to the set security level threshold, the transfer server performs the image authentication mechanism and sends an image authentication feedback to the data interaction request enterprise server, the image authentication feedback includes an image object and an image action requirement, and the data interaction request enterprise server records the image authentication data packet of the current time according to the image authentication feedback and sends it to the transfer server; Step 5, in step 4, if the transfer server determines that the security level is less than the set security level threshold, the interaction data packet is forwarded to the data interaction request enterprise server; If the transfer server performs the image authentication mechanism and the data interaction request enterprise server image authentication data packet passes the image authentication mechanism, the interaction data packet is forwarded to the data interaction request enterprise server; If the data interaction request enterprise server image authentication data packet does not pass the image authentication mechanism, the transfer server refuses to forward the interaction data packet and sends a warning message to the data interaction target enterprise server and the data interaction request enterprise server.

[0006] By using the above technical solution, a trusted interaction verification module is set for the data terminal of each enterprise on the supply chain, which can be implemented based on an intelligent agent or a computer with computing power; When an enterprise needs to interact data with a target enterprise on the supply chain, the server defined by the enterprise is defined as the data interaction request enterprise server, and the target enterprise is defined as the data transfer server. The data interaction request enterprise server sends a data interaction request to the data transfer server, and the data transfer server forwards the data interaction request to the trusted interaction verification module of the specified data interaction target enterprise server. The corresponding numbered trusted interaction verification module performs the data trusted exchange multi-party verification mechanism to verify the legality and security of the data interaction request; Adopting at least three-party cross-validation, the corresponding numbered trusted interaction verification module communicates based on the network address of the data interaction request. Since the trusted interaction verification module number is generated by using a random number algorithm, it is assumed in advance that the fraud party cannot obtain the number, so it is impossible to set additional communication fraud parameters intentionally, and therefore it is highly unlikely to achieve normal communication with the corresponding numbered enterprise server, nor can it obtain the pre-agreed ciphertext information. In specific applications, the ciphertext information can also be numbered, and the ciphertext ordering number can also be randomly generated to increase the verification difficulty, verify the legitimacy and security of the data interaction request enterprise server, and avoid the risk of data leakage caused by targeted communication fraud based on the target enterprise's special settings. After passing through the trusted exchange multi-party verification mechanism, the required data and security level tags are packaged into an interaction data packet and forwarded to the transit server. The transit server also needs to further perform an image authentication mechanism according to the security level. The purpose of the image authentication mechanism is to ensure that the individual or entity interacting is the identity they claim to be when the data security level is high. Through image authentication, the operator's facial features, actions, or possession of specific items can be verified to prove the authenticity of their identity. Image authentication can reduce or prevent fraud such as identity theft and account takeover, providing an additional layer of security for data exchange and transaction processes, especially when dealing with sensitive information or performing high-risk operations.

[0007] A more secure method for trusted exchange of enterprise data on the supply chain is constructed to ensure the secure interaction of supply chain data.

[0008] Optionally, in step 1, let N be the total number of trusted interaction verification modules, and i be the number of a specific trusted interaction verification module. The numbering formula is: ; If N is a single digit or a ten-digit number, then N is supplemented with 0 to form a three-digit number.

[0009] By adopting the above technical solution, the number of enterprises on the supply chain usually does not exceed one hundred, and a three-digit number can meet the numbering requirements, providing a raw standard number for the subsequent random number algorithm to generate a number, Optionally, in step 2, the method for generating cross-validation party numbers by using a random number algorithm is: let R be a random number algorithm, n be the number of cross-validation parties to be generated, n ≥ 3, and j be the generated number. The formula for randomly generating cross-validation party numbers is: ; wherein is the formula for randomly generating the kth cross-validation party number.

[0010] By adopting the above technical solution, the random number algorithm should be set to remove duplicates when generating numbers to avoid the small probability of generating the same number multiple times.

[0011] Optionally, in step 2, the specific method of cross-verification data interaction request legitimacy and security is: forwarding the data interaction request enterprise server network address corresponding to the data interaction request to the random number algorithm to generate the cross-verification party number corresponding to the trusted interaction verification module, the trusted interaction verification module requests the data interaction request enterprise server network address for cipher communication, if the communication feedback is obtained, the cipher is sent, if the cipher code is received, and the cipher code corresponding to the cipher database is matched, the cross-verification passes, and the trusted interaction verification module of the interaction data interaction target enterprise server feeds back the information of cross-verification passing. If all cross-verifications pass, the trusted interaction verification module of the interaction data interaction target enterprise server judges that the data interaction request enterprise server is legitimate and secure.

[0012] Optionally, the security level refers to S1, S2 and S3, S1 level data refers to ordinary data, S2 level data refers to confidential data, and S3 level data refers to top secret data.

[0013] Optionally, in step 3, the data corresponding to the data interaction request is labeled with a security level and a timestamp to form an interaction data packet.

[0014] Optionally, in step 4, the security level threshold is S2.

[0015] By adopting the above technical scheme, S2 and S3 level data should perform image authentication mechanism, and related authorized personnel need to record specified video to ensure data security.

[0016] Optionally, the image authentication mechanism includes the following specific steps: Step 1, let I be the video frame of image authentication feedback, is the output of face detection algorithm, ; Wherein represents the nth face detection frame detected; Step 2, let F be a feature extraction function, is the face bounding box, is the feature vector extracted from the face area; Step 3, let L be a live detection function, AL be a live detection result; The live detection function detection result can include blink detection, head movement, facial expression change; Step 4, let BA be a behavior analysis function, V be a video sequence, A(V) be an analyzed behavior mode; Step 5, let SM be a similarity matching function, is a reference feature vector, S is a similarity score; ; Step 6, let D be the authentication decision function, S be the similarity score, AL be the liveness detection result, and are the similarity and liveness detection thresholds, respectively; ; is the image authentication decision result, and the authentication decision result includes passing the image authentication mechanism and failing the image authentication mechanism.

[0017] By adopting the above technical solution, the image authentication record can be used as part of the audit and monitoring for post-analysis, investigation or dispute resolution. The image authentication can resist automated attacks (such as robot attacks), because such attacks usually cannot complete the actions or expressions that require human participation.
