<p>When transmitting data to be protected such as audio data by Bluetooth connection, authentication difficulty is switched according to the processing ability of the device to be a communication mate. Accordingly, even a device having a low processing ability can perform Bluetooth communication based on SDMI. Moreover, when the communication mate is a device having a high processing ability such as a personal computer, it is possible to provide sufficient countermeasure for hacking.</p> |
