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, wherein the audio-sensor inhibitor is positioned adjacent to the audio sensor of the 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 is configured to
- (i) detect the sound inhibited from being detected by the audio sensor of the communication device;
- (ii) generate the encrypted audio data by encrypting the detected sound using a cryptographic module;
- and
- (iii) provide the generated encrypted audio data to the communication device inhibited from detecting the sound.
An apparatus comprising:
- an audio-sensor inhibitor to inhibit detection of sound by an audio sensor of a communication device, wherein the audio-sensor inhibitor is positioned adjacent to the audio sensor of the communication device;
- and
- 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 of the sound inhibited from being detected by the audio-sensor inhibitor, the communication interface including a communication link to enable relay of the encrypted audio data between the communication interface and the communication device inhibited from detecting the sound.
