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: generating original accident information; and calculating a hash value of the original accident information, generating a Merkle root value, and transmitting the same together with the original accident information. Thus, 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 in a block chain, it can contribute to the speedy handling of traffic accidents. In addition, it is possible to reduce the overload of the block chain network by generating a Merkluk value to be stored in the block chain by hashing the same in units (1 to 10 minutes) before and after the accident time at a specific point in time.

    블록체인을 기반으로 사고정보의 위변조를 방지하여 무결성을 보장하는 전송 방법이 제공된다. 본 발명의 실시예에 따른 블록체인기반 무결성보장 교통사고정보 전송 방법은 원본 사고정보를 생성하는 단계; 및 원본 사고정보의 해쉬값을 계산하고, 머클루트(Merkle Root)값을 생성하여, 원본 사고정보와 함께 전달하는 단계;를 포함한다. 이에 의해, 사고유발 운전자의 생체정보와 사고위치, 차량속도와 함께 사고정보를 생성하고 블록체인의 블록에 저장할 머클트리 값을 생성하여, 사고정보 원본과 함께 경찰서 또는 보험사에 전송함으로써, 사고정보의 위변조를 방지할 수 있다. 또한, 사고정보의 열람기록 등 모든 관리기록 정보를 해쉬트리 형태로 블록체인으로 관리함으로써, 신속한 교통사고 처리에 기여할 수 있다. 그리고 특정시점의 사고시간 전후단위(1~10분)로 해쉬를 하여 블록체인에 저장될 머클루크 값을 생성하여, 블록체인 네트워크의 과부하를 절감시킬 수 있다.
