Abstract
When transmitting data such as audio data which require protection to be provided, difficulty levels of authentication are switched corresponding to processing power of equipments to communicate. Thus, for an equipment of low processing power may perform a Bluetooth communication based on the SDMI. Further, for a communicating counterparty which is an equipment of high processing power, such as a personal computer, sufficient countermeasures against hacking may be taken.
