According to one embodiment of the present invention, a method for managing driving record data based on a blockchain network includes the steps of: allocating a block number of a block to be created for driving record data collected by a driving recorder while driving a vehicle; generating the block using a server seed allocated from a server and a seed count value, which is a variable whose value is changed whenever the drive recorder generates a block in an off-line state; and transmitting a block hash value and block data of the generated block to the server. 일 실시예에 따른 블록체인 네트워크에 기반한 운행기록 데이터의 관리 방법은, 운행기록장치가 차량의 운행 중에 수집한 운행기록 데이터에 대해 생성할 블록의 블록번호를 할당하는 단계, 서버로부터 할당되는 서버시드(server seed) 및 상기 운행기록장치가 오프라인 상태에서 블록을 생성할 때마다 값이 변경되는 변수인 시드카운트(seed count) 값을 이용하여 블록을 생성하는 단계 및 상기 생성된 블록의 블록해시값 및 블록데이터를 상기 서버에 전송하는 단계를 포함한다.
