Express delivery information privacy protection system based on blockchain, and protection method thereof

The invention discloses an express delivery information privacy protection system based on a blockchain, and a protection method thereof. The method records all operational motions of an express delivery enterprise for user data through a blockchain auditing platform, the operation compliance of the express delivery enterprise is enhanced, and the express delivery enterprise can be effectively prevented from illegally obtaining personal information. Meanwhile, a user can read a user data visitor record through an authorization record recorded in the blockchain, the access permission of the express delivery enterprise for the user data is revoked, and the sense of control of the user for personal data is enhanced. In addition, a ciphertext express waybill is used for replacing a plaintext express waybill, so that a possibility that the user data is leaked in each link of an express delivery business process can be lowered. An express delivery package logistics tracking scheme based on the blockchain can assist the user in checking the logistics situation of the express delivery package at any time in a blockchain system, and logistics information which can not be tampered on the blockchain can provide proof-providing information for disputes including delivery losing claims and the like.

A method for protection and control of automobile CAN communication interruption

The present invention relates to the technical field of Internet of Vehicles, and provides a method for protecting and controlling automotive CAN communication interruption. The method specifically includes the following steps: S1, T-box receives a vehicle network disconnection command sent by a mobile terminal, and uploads it to the CAN wiring harness; S2. The body controller BCM and the engine controller MCU wake up based on the vehicle network disconnection command, the body controller BCM uploads the vehicle network disconnection command, and the instrument reads the vehicle network disconnection command; S3. The instrument is disconnected based on the vehicle network The instruction monitors in real time whether the vehicle meets the CAN communication interruption condition. If the detection result is yes, the CAN communication of the vehicle is interrupted, and the CAN communication interruption information is fed back to the instrument. Based on the vehicle network communication architecture, a vehicle CAN communication is designed. The control method of interruption and recovery of the communication network quickly realizes the interruption control of the network communication of the vehicle, and improves the user's sense of control over the vehicle; in addition, it improves the passive anti-theft function of the traditional automobile relying on its own body anti-theft system to realize the active protection of the vehicle.
