System and method for matching purchase records to mobile devices

A mobile device and sales transaction matching system comprising:

• i) a database;
• ii) a server computer having a memory, a processing unit accessing said memory, a network interface coupled to said processing unit and operatively coupled to said database, and a specialized server software application operating on said processing unit, wherein said server computer is adapted to communicate with a sales transaction server system and a mobile device location data server system;
• iii) said specialized server software application adapted to:
• 1) retrieve a set of purchase records from said sales transaction server system;
• 2) retrieve a set of mobile data points from said mobile device location data server system, wherein said set of mobile data points corresponds to a first mobile device;
• 3) for each mobile data point within said set of mobile data point, define a mobile data sphere;
• 4) for each purchase record within said set of purchase records, define a transaction sphere;
• 5) compare each said mobile data sphere with each said transaction sphere to determine a list of over lapping purchase records for each mobile data point, thereby forming a plurality of lists of over lapping purchase records for said first mobile device, wherein said mobile data sphere of said each mobile data point overlaps with said transaction sphere of each purchase record within said list of over lapping purchase records corresponding to said each mobile data point;
• 6) create a similarity function for determining similarity between transactions;
• and
• 7) apply said similarity function to each pair of purchase records within said plurality of lists of over lapping purchase records to determine purchase records of a user of said first mobile device.
