Abstract
An apparatus includes an audio-sensor inhibitor configured to inhibit detection of sound by an audio sensor of a communication device, and a secure communication interface coupled to the audio-sensor inhibitor, the secure communication interface being configured to transmit encrypted audio data from the secure communication interface to the communication device, wherein the communication interface generates audio data using a secure-interface audio sensor, and generates the encrypted audio data by encrypting the audio data using a cryptographic module.
Claims20
An apparatus comprising:
- an audio-sensor inhibitor configured to inhibit detection of sound by an audio sensor of a communication device;
- and
- a secure communication interface coupled to the audio-sensor inhibitor, the secure communication interface configured to communicate encrypted audio data from the secure communication interface to the communication device, wherein the secure communication interface (i) generates audio data using a secure-interface audio sensor, and (ii) generates the encrypted audio data by encrypting the audio data using a cryptographic module.
An apparatus comprising:
- an audio-sensor inhibitor to inhibit detection of sound by an audio sensor of a communication device;
- a communication interface coupled to the audio-sensor inhibitor, the communication interface configured to receive an inbound wireless communication data transmitted from an external accessory that includes a secure communication interface, the inbound wireless communication data including encrypted audio data, the communication interface including a communication link to enable relay of the encrypted audio data between the communication interface and the communication device.
