An image processing system includes circuitry. The circuitry accepts, from a user, an input of information to be registered. The circuitry registers the inputted information as registered information. The circuitry generates tracing data to be used for tracing the registered information. The circuitry outputs the tracing data. The circuitry associates access authorization to an access log for the registered information with the tracing data. The circuitry accepts an input of the tracing data. The circuitry acquires the access log that is associated with the inputted tracing data, and displays the acquired access log.
