Geographical comparison system and method
First Claim
1. A method for comparing a first location and a second location, the method comprising,generating a first binary representation from geographic information based on the first location,generating a second binary representation from geographic information based on the second location,associating an uncertainty with at least one of the first binary representation and the second binary representation,bitwise comparing the first binary representation and the second binary representation, and,associating an uncertainty with the bitwise comparison.

Abstract
Systems and methods to create venue tokens that provide generalized geographic information while preserving location specific data. In one embodiment, a Universal Location Descriptor (ULD) translator converts location data into a geocode that in one embodiment is a binary code. Location information can include a street address, zip code, directional information, destination, velocity information, latitude and/or longitude, etc. The geocode can then be encrypted to generate a token. Relative geographic similarities can be identified by comparing geographic information from the tokens, thereby allowing similarly situated individuals and/or organizations, service providers, etc., to be identified without disclosing specific location identities of those parties seeking such privacy. The comparison of token geographic information can provide a probabilistic output that, in one embodiment, can be customized using an application-dependent threshold, to generate only those outputs satisfying a specified probability measure.
