Abstract

A proximity network map defines who and what objects have come in contact of each other including location and time. This map selects the list people who have come in contact with known infected people based on contagious disease epidemiology criteria to control its spread, or to prevent radiation poisoning, limit bio-chemicals exposure, etc. These people then undergo testing and quarantine procedures. It monitors hygiene practices and reduces nosocomial infections in hospitals and mitigates the pandemic flu threat by controlling contamination. It controls people interaction, information flow in a high security environment, control crime or gang activities. Each person or object carrying a proximity-sensing unit with unique ID records all units it encountered over a period of time. This information is stored with time stamp in a relational database and transferred to network servers. The databases are then replication throughout via a central web database server for retrieval and analysis.

Claims

1. A system for generating a contact or proximity network map (PNM) from the interaction between a mobile user and its neighbors and objects. This contact tracking technology comprises of:

A remote (wireless) contact or proximity sensing unit (PSU) capable of exchanging unique ID of the person or object it interacts with and also contact proximity and time information among the PSU of the interaction parties;

A PSU capable of storing a unique ID;

A PSU capable of keeping an embedded real-time clock;

A PSU capable of storing Proximity Network Map (PNM) over a period of time;

A relational database storing the PNM (also in Matrix format);

A system capable of transferring the PNM to another device for downloading to a central system database;

A replication and synchronizer for the database;

A back end database and program capable of searching for contact tree information backward or forward;
