The application discloses a kind of configuration class data's cache ORM systems, specifically relates to software application technical field, including cache structure definition module, for by Groovy script configuration class data in relational database is converted into Redis specific data structure;Cache synchronization control module is coupled with the data of cache structure definition module.The application is systematically solved through Vickrey auction mechanism and reverse index incremental update the consistency problem of distributed multi-node concurrent modification cache, eliminates cache surprise group effect;Through alliance chain storage and zero-knowledge proof audit, realize the full-process tamper-proof traceability and privacy protection compliance verification of cache operation;Through the construction of immune network antibody library and complement cascade response, realize the active perception and dynamic defense of cache penetration attack, three big mechanisms work together, reduce development and operation cost, improve the security, credibility and management efficiency of cache system.

The invention discloses a cooperative hardware security terminal architecture based on a glass vacuum cavity, which comprises an independently arranged glass vacuum cavity security module, can cooperatively work with an existing terminal main processor, and realizes hardware-level security upgrade on the premise of not influencing original performance and use experience. The glass vacuum cavity adopts two selectable sealing processes, so that both mass production and flexibility are considered; and a national security level hardware security unit is integrated in the cavity to realize key storage and encrypted transmission. An end-cloud collaborative architecture is adopted, sensitive data are not stored locally, and the security module can realize physical transplantation. The method is high in compatibility, does not depend on an advanced process, is high in physical attack resistance, can be widely applied to various smart phones and high-security-level terminals, and has high practicability and market value.

The invention relates to the field of agricultural product quality monitoring, in particular to an agricultural product tracing link-oriented abnormal event monitoring method, which comprises the following steps of: S1, defining a batch coding rule and an event type dictionary, and establishing a tracing relation model; s2, based on the traceability relation model, deploying sensing data acquisition equipment at each key control point of an agricultural product traceability link, deploying an edge computing gateway at each place, and completing credible data chaining; s3, unifying data of different sources to a standard timeline, establishing association keys according to batches, places and devices, and performing preprocessing; s4, constructing an anomaly detection model which comprises a time sequence prediction model, a visual anomaly model, a rule anomaly model and a graph anomaly model, and carrying out anomaly detection based on the preprocessed data; s5, calculating a risk score by adopting an evidence fusion strategy, and obtaining an output alarm packet; and S6, according to the output alarm packet, performing traceability positioning and influence range evaluation based on the traceability relation model. The agricultural product quality abnormity monitoring efficiency and reliability are effectively improved.

The utility model relates to audio and video recording technical field, and disclose a kind of portable synchronous audio and video recording equipment, including main casing, main casing inside integrated operating system, front camera, rear camera assembly, touch display screen, built-in battery module and double optical drive module;Rear camera assembly is rotatably connected with main casing by flip structure.This utility model is integrated operating system, double camera module, touch display screen, battery module and double optical drive module by main casing, rear camera assembly is rotatably connected by flip structure, so that flip structure makes rear lens can multi-angle shooting, touch screen is directly embedded, supports real-time marking, editing in recording, greatly improves the efficiency of separate equipment;Machine size is smaller, weight is reduced, suitable for single hand holding outdoor operation;The double hard disk of the utility model is stored by SATA interface mirror image and double optical drive synchronous burning, so that double hard disk real-time hot spare, generates read-only physical evidence chain.

The invention provides a data processing method and device and related equipment, and relates to the technical field of block chains, cloud computing, artificial intelligence and information.The data processing method comprises the steps that multiple pieces of metadata are obtained from a pre-constructed source database, and the multiple pieces of metadata are divided into hot metadata, cold metadata and new metadata; performing correction processing on first hot metadata which does not meet a preset standard in the hot metadata, screening the new metadata to obtain first target metadata meeting a first auditing condition, and screening the cold metadata to obtain second target metadata meeting a second auditing condition, the hot metadata further comprises second hot metadata meeting the preset standard; and storing the first hot metadata, the second hot metadata, the first target metadata and the second target metadata after correction processing into a block chain. In this way, the accuracy of the metadata is improved.
