Furthermore, the method comprises generating the challenge based, at least in part, the one or more characteristics.

Method and apparatus for authorizing a user or a user device based on location information

An apparatus for augmenting associations between places and fingerprints includes a processor and memory storing executable computer code causing the apparatus to at least perform operations including detecting fingerprint data from a beacon device(s), as the apparatus traverses one or more physical places. The fingerprint data corresponds to generated summaries of radio information corresponding to the physical places. The computer code may cause the apparatus to compare fingerprint data detected from a subset of beacon devices with canonical fingerprint data, including initial fingerprint data, corresponding to physical places to determine a closest match. The computer code may cause the apparatus to determine a location of the apparatus in the physical place based on determining fingerprint data, detected from the subset of beacon devices in the physical place, that most accurately resembles canonical fingerprint data corresponding to one of the physical places. Corresponding methods and computer program products are also provided.

A method and apparatus are provided to permit location discovery, including location discovery in indoor settings. The method may identify a wireless fingerprint present at a geographical location and determine whether the wireless fingerprint corresponds to a previously observed wireless fingerprint associated with the predefined geographical location. A new wireless fingerprint and a geographical location, or bind, may be received by the system and the system may evaluate whether or not the new bind is erroneous or not, or if the new bind is an improvement over existing binds in determining whether or not to accept the new bind.

Method and apparatus for constructing a user-generated geographical system

A method and apparatus are provided for on-device positioning using compressed fingerprint archives. The method and apparatus may be configured to provide compression of localization fingerprints, to facilitate efficient on-device positioning based on the RF fingerprint model, and to estimate the physical distance between two or more devices.
