Apparatus and method for address privacy protection in receiver oriented channels

An apparatus with address privacy protection and that shares a privacy key with a second wireless device, comprising:

• means for generating a first resolution tag using a pseudo-random function with a seed value and the privacy key as input arguments, wherein the privacy key is only known to the apparatus and the second wireless devices;
• means for generating a privacy address for the apparatus based on the seed value and the first resolution tag;
• and
• means for transmitting a packet to the second wireless device, wherein the packet includes the privacy address and the first resolution tag.

A computer program product, comprising:

• computer readable medium, comprising:
• code for causing a computer to generate a first resolution tag using a pseudo-random function with a seed value and a privacy key as input arguments, wherein the privacy key is only known to the computer and a second wireless devices,
• code for causing a computer to generate a privacy address based on the seed value and the first resolution tag:
• and
• code for causing a computer to transmit a packet to the second wireless device, wherein the packet includes the privacy address and the first resolution tag.

A watch with address privacy protection and that shares a privacy key with a second wireless device comprising:

• means for generating a first resolution tag using a pseudo-random function with a seed value and the privacy key as input arguments, wherein the privacy key is only known to the watch and the second wireless devices;
• means for generating a privacy address for the watch based on the seed value and the first resolution tag:
• and
• means for transmitting a packet to the second wireless device, wherein the packet includes the privacy address and the first resolution tag.

A headset with address privacy protection and that shares a privacy key with a second wireless device, comprising:

• means for generating a first resolution tag using a pseudo-random function with a seed value and the privacy key as input arguments, wherein the privacy key is only known to the headset and the second wireless devices;
• means for generating a privacy address for the headset based on the seed value and the first resolution tag;
• and
• means for transmitting a packet to the second wireless device, wherein the packet includes the privacy address and the first resolution tag.
