Abstract
Systems and methods are directed to securely identifying positioning information and include a plurality of APs configured to facilitate wireless communications within a servicing area, an infrastructure entity, communicatively coupled to each of the APs, and configured to store and process subscription information, positioning information, QoS information indicative of resolution levels of the positioning information, and encryption/decryption information specific to each of a plurality of subscribing member wireless devices. As a wireless device enters the servicing area, the wireless device establishes a first level of communication with the infrastructure entity via at least one AP, and requests positioning information to the at least one AP which is then forwarded to the infrastructure entity. Upon verifying that the wireless device is a subscribing member, a second level of communication is established that securely provides position information to the wireless device, based on the encryption/decryption information specific to the wireless device.
