Multi-tenant end-to-end data security isolation and control system and method
ActiveCN122093199AGuaranteed immutabilityuniqueness guaranteedTelemetry/telecontrol selection arrangementsSecuring communicationAuthenticationReliability engineering
This invention discloses a multi-tenant end-to-end data security isolation and control system and method, belonging to the field of vehicle network data security. It aims to solve the problems of easy data crosstalk, discontinuous isolation, unreliable trust benchmarks, and difficulty in compliance traceability in multi-tenant scenarios. The system generates a tenant root identifier (TID) for vehicle enterprise tenants, which, together with the device sub-identifier (DID), forms a tenant identifier chain. This chain is synchronized with a trusted authentication center to establish a vehicle-cloud hardware-level trust root. When the vehicle terminal accesses the system, it completes two-way identity authentication and allocates a dedicated message queue telemetry transmission MQTT topic partition and access permissions according to the TID. The terminal collects time-series vehicle control data and generates encrypted data frames with intrinsic identifiers and checksums for uploading. The access gateway performs dual isolation verification before transparent transmission. Data is forwarded to an independent logical storage partition for isolated storage according to the TID. This invention achieves strong hardware-level isolation, real-time verification, and full traceability throughout the entire end-to-cloud chain, effectively preventing cross-tenant data leakage.

A police car end electronic data evidence method, system and computer device
This invention discloses a method, system, and computer equipment for electronic data forensics in police vehicles. The method includes: confirming whether the vehicle's onboard data storage device has read permissions; if read permissions exist, the investigating officer performs bidirectional authentication between the vehicle-mounted forensics equipment and the identity authentication module in the public security platform, activating and authorizing the secure, legal, and operable nature of the vehicle-mounted forensics equipment; if read permissions do not exist, data is directly read from the vehicle-mounted data storage device; and different data integrity checks and extractions are performed based on the two communication protocol types of the vehicle-mounted data storage device. This invention, in police enforcement scenarios, overcomes permission barriers and equipment damage constraints, enabling rapid acquisition and analysis of onboard data.
