9 . A wireless accessory device comprising:
a memory comprising computer-executable instructions; and
one or more processors configured to access the memory and execute the computer-executable instructions to perform operations comprising:
receiving, by the wireless accessory device from a electronic device, a timer reset packet, wherein the timer reset packet includes a predetermined time period and a near-owner authorization token;
identifying, by the wireless accessory device, the near-owner authorization token;
transitioning, by the wireless accessory device based at least in part on the identification of the near-owner authorization token, to a near owner mode; and
when in the near-owner mode, broadcasting, by the wireless accessory device, a near-owner mode packet after expiration of the predetermined time period.
10 . The wireless accessory device of claim 9 , wherein the memory comprises additional computer-executable instructions and the one or more processors are further configured to access the memory and execute the additional computer-executable instructions to perform additional operations comprising to generate a set of cryptographic keys based on a key material, wherein the key material is collaboratively generated with the electronic device.
11 . The wireless accessory device of claim 10 , wherein:
the set of cryptographic keys includes keys for one or more privacy periods of the wireless accessory device; and
the memory comprises additional computer-executable instructions and the one or more processors are further configured to access the memory and execute the additional computer-executable instructions to perform additional operations comprising changing, each privacy period, one or more keys used to generate a hardware address with the wireless accessory device.
12 . The wireless accessory device of claim 9 , wherein the predetermined time for expiration based at least in part on at least one of a location of the wireless accessory device or a motion state.
13 . A computer-implemented method comprising:
scanning, by a first processor of an electronic device, for a beacon advertisement that is broadcast by a wireless accessory device in a near-owner mode, wherein the wireless accessory device is in the near-owner mode when the electronic device is within range of the wireless accessory device;
detecting, by the electronic device, the beacon advertisement broadcast by the wireless accessory device;
retrieving, by the electronic device, an identifier broadcast within the beacon advertisement;
based on a result of a comparison between the identifier to at least one expected identifier, sending, by the electronic device to the wireless accessory device, a timer reset packet and an authorization token for the wireless accessory device to remain in the near-owner mode, wherein the timer reset packet includes a predetermined time period; and
managing, by the electronic device, a second processor of the electronic device in sleep mode for the predetermined time period.
14 . The computer-implemented method of claim 13 , wherein the identifier is a hardware address.
15 . The computer-implemented method as in claim 13 , further comprising:
determining whether the wireless accessory device associated with the beacon advertisement is associated with an account on a mobile electronic device.
16 . The computer-implemented method of claim 13 , further comprising:
generating a set of cryptographic keys based on a key material, wherein the key material is collaboratively generated with the wireless accessory device.
17 . The computer-implemented method of claim 16 , wherein:
