Abstract

The invention relates to the field of block chains, and specifically provides a self-certification notarization method and system based on the block chain. The method comprises the following steps: acquiring behavior event information uploaded by a user, encrypting the behavior event information to generate encrypted behavior event information, generating corresponding behavior event abstract information according to the encrypted behavior event information, and performing secondary encryption according to the behavior event abstract information to form encrypted abstract information; and acquiring the timestamp information, storing the acquired encrypted behavior event information and the encrypted abstract information in storage nodes of a security blockchain, and synchronizing data among the nodes, thereby achieving a notarization effect. According to the method and the system, the authenticity of the behavior event and the data is protected by uploading a certain behavior event andmaterial to the blockchain system and utilizing the non-tampering characteristic of the blockchain, professional notarization personnel do not need to be set, and evidence storage of a user and evidence collection of a judicial institution are facilitated.
