Abstract: A method for geographic fingerprinting for monitoring of home services Interactions between a provider of a home service and a patient. The method and system are directed to presence determination (who is at a specific location at a specific time) rather than GPS location services (pinpointing that location). This service will uses a multi-pass authentication system to verify the co-located presence of a patient and service provider along with verification of time and geographic location of the patient and provider against multiple pre-specified static and dynamic parameters.

Abstract: Systems and methods for social networking and digital media aggregation represented as a three-dimensional virtual world within a standard web browser are described. In one embodiment, multiple, independent groups of users interact with each other inside a dynamic, three-dimensional virtual environment. These groups may be mutually exclusive and members interact only with other members within the same group. In this manner, system architecture and server requirements may be greatly reduced, since consistent environmental state needs to be maintained only for a small number of interacting participants—typically less than one dozen.
