Privacy enhancements for wireless devices
First Claim
1. A method executed in a wireless device, the method comprising:
- obtaining a first network information record for a first wireless network, the first network information record including network access information for the first wireless network and a usage policy specifying a condition under which the first network information record should be used, wherein the network access information for the first wireless network includes instructions for dynamically generating a network name for the first wireless network using an algorithm and further includes an input parameter to initialize the algorithm;
storing the first network information record in a set of network information records for known networks; and
searching for a wireless network to join, using the set of network information records,wherein searching for a wireless network to join includes;
determining, based on the usage policy of the first network information record, whether the condition is satisfied; and
searching for the first wireless network only if the condition is satisfied, wherein searching for the first wireless network includes executing the algorithm to dynamically generate the network name of the first wireless network and using the dynamically-generated network name to detect the first wireless network.

Abstract
A wireless device can obtain a network information record from another device operating as a credential source. The network information record can include network access information for a wireless network (e.g., SSID and password) and a usage policy specifying conditions under which the wireless device should search for the wireless network (e.g., temporal and/or spatial conditions). The wireless device can implement the usage policy by searching for the wireless network only when the conditions are satisfied. In some instances, the network access information can include instructions for dynamically generating time-varying network access information, and the wireless device can use the instructions to generate network access information during a search for wireless networks.

13. An electronic device comprising:
-
a data communication interface to communicate with a wireless network; a storage medium to store a set of network information records for known networks; and a processor coupled to the data communication interface and the storage medium, the processor configured to; obtain a first network information record for a first wireless network, the first network information record including network access information for the first wireless network and a usage policy specifying a condition under which the first network information record should be used, wherein the network access information for the first wireless network includes instructions for dynamically generating one or both of a network name or an access credential using an algorithm and further includes an input parameter to initialize the algorithm; store the first network information record in the set of network information records for known networks; and search for a wireless network to join, using the set of network information records, wherein searching for a wireless network to join includes determining, based on the usage policy of the first network information record, whether the condition is satisfied, and searching for the first wireless network only if the condition is satisfied, wherein searching for the first wireless network includes executing the algorithm to dynamically generate one or both of the network name or the access credential and using the dynamically-generated network name or access credential to detect the first wireless network. - View Dependent Claims (14, 15, 16, 17, 18)
