Method for transmission of integrity guarantee traffic accident information based on blockchain

摘要

A transmission method that prevents forgery and falsification of accident information based on block chain and guarantees integrity is provided. A block chain-based integrity guarantee traffic accident information transmission method according to an embodiment of the present invention comprises the steps of: generating original accident information; and calculating a hash value of the original accident information, generating a Merkle Root value, and transmitting it together with the original accident information. In this way, accident information is generated along with the biometric information of the accident-causing driver, accident location, and vehicle speed, and a Merkle Tree value to be stored in the block of the block chain is generated and transmitted to the police station or insurance company along with the original accident information. Forgery can be prevented. In addition, by managing all management record information, such as the reading record of accident information, in the form of a hash tree, it can contribute to the rapid handling of traffic accidents. And, it is possible to reduce the overload of the blockchain network by generating a Merkluk value to be stored in the blockchain by hashing it in units (1 to 10 minutes) before and after the accident time at a specific point in time.
