The vulnerability of electronic data itself makes the originality of digital forensic information become the key to the process of computer evidence identification. Based on smartphone forensics, using the ECDSA signature mechanism, this paper puts forward an anti-repudiation scheme to prove the integrity of electronic evidence. The scheme can transfer the obtained forensics information in real-time and safely during the operation of the smartphone system, and fix the evidence to ensure its integrity. On the premise of some cryptographic assumptions, the security of the scheme is proved.
