Abstract
A recording unit records an operation log. A storing unit included in a temper-resistant chip stores therein a secret key unique to an image reading apparatus. An encrypting unit included in the temper-resistant chip encrypts recorded operation log with stored secret key. A transmitting unit transmits information including encrypted operation log to a server.
Claims20
An image reading apparatus that is connected to a server via a network, the image reading apparatus comprising:
- a recording unit that records an operation log;
- a tamper-resistant chip including
- a storing unit that stores therein a secret key unique to the image reading apparatus;
- and
- an encrypting unit that encrypts recorded operation log with stored secret key;
- and
- a transmitting unit that transmits information including encrypted operation log to the server.
An image reading apparatus that is connected to a server via a network, the image reading apparatus comprising:
- a recording unit that records an operation log;
- a generating unit that generates a hash value corresponding to recorded operation log;
- a tamper-resistant chip including
- a storing unit that stores a secret key unique to the image reading apparatus;
- and
- an encrypting unit that encrypts generated hash value with stored secret key;
- and
- a transmitting unit that transmits information including encrypted hash value and the recorded operation log to the server.
A computer program product comprising a computer usable medium having computer readable program codes embodied in the medium that when executed cause a computer to execute:
- recording an operation log;
- encrypting recorded operation log with a secret key that is unique to an image reading apparatus, the secret key being stored in a tamper-resistant chip installed in the image reading apparatus;
- and
- transmitting encrypted operation log to a server that is connected to the image reading apparatus via a network.
