This invention discloses a method for confirming ownership of physical assets in a supply chain and hedging financing risks based on dynamic graphic codes, belonging to the field of supply chain finance technology. The invention includes: physically demarcating the financing target through a one-time destructive encapsulation and attaching a first identification code to its outer layer; dynamically generating and updating the first identification code based on the spatiotemporal and physical attributes of the financing target; the funding party scanning the first identification code to confirm the authenticity of the asset by comparing physical integrity and data consistency; when a preset risk condition is triggered, the funding party generates a second identification code that is logically mutually exclusive with the first identification code, used to prove to a third party that the rights and interests of the target asset have been locked or transferred. This invention eliminates the need for high-cost IoT sensors, achieving movable asset ownership confirmation and financing risk hedging through low-cost physical encapsulation and dynamic graphic codes, and has the advantages of simple implementation, high reliability, and ease of promotion.

The invention discloses a fuel collection and preparation whole-process information security management and control system based on dynamic authority and physical isolation. The system comprises a central management and control platform, a security isolation gatekeeper, a field operation terminal and a physical execution unit. The platform generates a dynamic authorization instruction based on the four-dimensional feature model, and unidirectionally transmits the dynamic authorization instruction to the terminal after passing through a gatekeeper stripping protocol; the terminal verifies the timeliness of the instruction and the validity of the spatial features, and sends a driving signal to the physical equipment in combination with the identity information of the operator; physical equipment adopts an electromechanical locking and composite authentication mechanism, and can be unlocked only by receiving a driving signal and an entity identity certificate at the same time. According to the method, a network attack path is isolated and cut off through a protocol, and man-machine refined management and control are realized by utilizing a dynamic permission and physical interlocking mechanism, so that data counterfeiting and violation intervention in a fuel collection and preparation process are effectively prevented.

The application provides a verifiable resale attribution and dispute resolution method and system for fine-grained structured data transactions. In the sales stage, a unified data processing specification is established through public universe and three-state normalization processing, different buyers are allocated different column views and bit map bindings are generated, the normalized data is embedded, locally sensitive hash is discretized and minimum hash digest is generated, the buyer binding receipt leaf is organized into an authentication data structure, and the root digest is anchored to the alliance chain smart contract. In the resale stage, the sampling position is determined by the on-chain unpredictable random seed, the authentication path verification and normalization recalculation are executed by the independent committee node to confirm the authenticity of the resale object. In the dispute stage, the suspicious sample is extracted and the disclosure digest is confirmed by the committee threshold, and the dispute object is locked. The proving party generates zero-knowledge proof to compare the coincidence count between the candidate buyer digest and the disclosure digest, and outputs the accusation, exclusion or retention judgment three-state ruling result according to the preset accusation threshold and exclusion threshold. Without disclosing the plaintext delivery data, the application provides a verifiable object authenticity verification channel for legal resale, and a privacy protection attribution mechanism based on similarity detection and double threshold ruling for illegal resale or data leakage.

The utility model relates to a disposable tearing label, which comprises a first mounting piece, a second mounting piece, a third mounting piece and a fourth mounting piece, opposite second hooking parts are arranged on the inner side surface of the second mounting piece; the second mounting piece comprises a ridge part, and the two sides of the ridge part are connected with the corresponding sheet bodies through tearing points; the second hooking parts are arranged on different sheet bodies; when the first hook buckle part and the second hook buckle part are matched, the first installation piece and the second installation piece are oppositely arranged and connected in a buckled mode, and the disposable tearing label is in a first connected state. The tearing point is damaged, the sheet body and the ridge part are separated, and the disposable tearing label is switched from the first state to a second state in which the ridge part of the first installation part and the ridge part of the second installation part are separated; the label can be connected with clothes, handbags or shoes, if the goods need to be used normally, the label needs to be damaged conveniently, and otherwise only try-on can be achieved; in this way, use traces of the goods can be reduced, and replacement of the goods can be avoided.

The present disclosure relates to an object authenticity identification method, an object authenticity identification device, a storage medium and an electronic device. The object authenticity identification method comprises: acquiring shooting data of an object to be identified collected by a shooting device at different shooting distances; wherein the shooting data comprises picture data and / or video data; determining image information corresponding to each shooting distance according to the shooting data; performing authenticity identification on the image information corresponding to each shooting distance by using a classifier corresponding to each shooting distance, to obtain authenticity identification results corresponding to each shooting distance; and obtaining a final authenticity identification result of the object to be identified according to the authenticity identification results corresponding to each shooting distance. The object authenticity identification method can solve the problems of low accuracy and poor user experience in authenticity identification.
