Abstract: A logging system and method based on a one-way hash function are described. The system includes a user system, a trusted third party, and a verifier. The method includes the following steps. The user system records a log file and initializes a message authentication code key and an image code.

The verifier then verifies the integrity of the check value and the image code sequence through the trusted third party. The trusted third party checks if the image code sequence obtained by the hash calculation equals to the check value through the one-way hash function, so as to verify that the log file of the user system has not been modified.
