The Network Finder Project

1. The Network Finder Project Members: Emery Sanford Igor Spivak Jeremy Bishop Selorm Oklu Terry Tianyi Zhu

2. Goal of Project Location management of Items Location management of People

3. Application Scope • Business • Individuals • Government

4. Application Scope: Business Manufacturing Commercial

5. Application Scope: Individual

6. Application Scope: Government

7. Innovative Capabilities • Easy and cheap way to track items • User-friendly interface • Remote access

8. User Benefits • Never lose anything again • Save time and worry • Security

9. Searchable database of items with Query capabilities • Find items in that building only Core Capabilities

10. To locate items in the database and display a visual map or a • relative location • As well it will allow for a customizable scale

11. Customizable interface depending on intended uses. Businesses have different needs from individuals and even from other businesses. Allows us to integrate into other applications and industries easily and affectively. Ability to store or record movement over time will be essential. Statistical data will also be useful for some of our clients.

12. Security will have new Meaning to the individual, Business, government, and society as a whole. Government agencies, military, and prison systems will be reshaped and reconfigured for the better. The nature of business will be Changed completely with Location management – which Will influence time management and asset management.

13. Safer University Using a GPD enables watch, cell phone, PDA or any other tag on a person and connected to the network, the network finder can be used as a security measure. Walking home from campus, you can have friends or family track you to make sure you get home safely.

14. Cashier-less Supermarket • Network finder can be used to implement a cashier-less supermarket • Networkable bar codes in the network finder database • Virutal exit gate • Saves time, money, and is more efficient – better security

15. Smart Tags Replace Bar-Codes • Professor ……..

16. Immediate Functions Deferred functions

17. Immediate Functions • Pinpoint the location of an individual or object • Issue an alert if person or object leaves specified zone

18. Deferred functions • Compile and present statistics (ie. average speed, distance covered, time spent in location, patterns, etc.) • Trip mapping to show path of travel and location history (ie. what roads the car has used)

19. Throughput large and completion time small • Service will work seamlessly on low performance as well as high performance machines to open networked finder capabilities to more people • Pinpoint location being quick is priority (the core function of the finder)

20. Minimize network traffic to keep data flowing quickly to users searching for objects while still serving a large number of people. This would reduce hardware costs and increase revenue. • This would be accomplished by only linking to the network if a user specifically asks where something is. Tags would lay idle until the user specifically asks for a location. Obviously, in the case of nuclear weapons and such, constant network attention would be needed. Finding keys, however, would only require network attention when the user asks for it.

21. We would offer different levels of finding to involve more people into the network. For example, the most basic finding capability would be available for very little money, but the user would only be allowed 10-20 tags. Large companies and wealthy people could invest hundreds if not thousands of dollars to tag millions of items and install very accurate locating beacons within their homes or businesses. This would help overcome network effects.

22. Given an effective search algorithm, most additional functions (collecting statistics, etc.) can be reduced in order to improve network performance. Ideally, these functions should not be integral to the finder system, but performed by machines which may interact with the finder system as clients. The main function, once again, is performing quick and accurate searches.

23. Scalability

24. 250 million user capability initially (~100 million AOL Instant Messenger users. We think more people will want to use this service than AIM) • The system should be highly scalable in order to include billions of users after catching on

25. Networked finding capabilities might become as standard as a refrigerator in a house, where every individual has to have one to fit in with society and function properly, so we want to be ready for this • Peer to peer communication would be very useful when the system grows popular. Less network traffic would be needed if my laptop could simply ask your laptop where it is instead of linking up to a satellite. This would only be possible with many users in close proximity.

27. Second Stage Architecture Client Browser Field Access capabilities (PDA/Cell Phone) A Location Transmitter system GPS Satellite, etc. Location/Data Server Area Transceiver TAG TAG TAG TAG

28. Security Overview • Proprietary, secure protocol allows only for the company’s servers to interface with TAGs and client browsers • Location Data stored on a secured, audited server; clients have access only to authorized Location Data • Access for authorized clients only (password or biometric if needed) • Access channel encrypted with asymmetric tokens
