The application relates to a kind of implementation methods of verifiable Internet of Things device data asset transaction, based on the data seller, blockchain and data buyer involved in Internet of Things data asset transaction system, the process for realizing verifiable data asset transaction is as follows: data seller publishes encrypted data on blockchain through smart contract, data buyer requests data according to needs and submits verification request.Smart contract is responsible for verifying the integrity and authenticity of data, and transmits decryption key to data buyer after verification.The data buyer decrypts the data using the key and completes the transaction.If the buyer finds that the decrypted data is abnormal, the smart contract is called to initiate arbitration.Through the confusion encryption mode, RSA accumulator technology, hash verification mechanism and on-chain arbitration mechanism, these attack behaviors are effectively resisted, and the privacy, integrity and verifiability of data transaction are ensured.

A method for counting personnel entering and exiting a coal mine based on combined target tracking includes the following steps: the counting system is started and enters the working state; a bounding box of the mine entrance area in the video surveillance is selected; the corresponding video stream is captured from the obtained surveillance video; the output personnel detection location box and safety helmet detection location box are input into the personnel tracking module, and the target tracking sequence of personnel and the target tracking sequence of safety helmets are output; the position status of the safety helmet is used to assist the matching score of personnel tracking; the IOA between the personnel location detection box and the mine entrance area in each frame of the target tracking sequence of each personnel is calculated; the IOA between the safety helmet location detection box and the mine entrance area in each frame of the target tracking sequence of each safety helmet is calculated; the calculation results are used to define whether each personnel and safety helmet have entered the mine; and the number of people entering and exiting the mine is counted based on the matching results.
