System and method for synchronizing electronic poll book voter databases
View Patent ↗The present invention is directed to a system and method for synchronizing electronic poll book voter databases. The system includes a plurality of electronic poll books in communication over a network, each poll book having a unique identifier and each including a voter database of voter information. Each poll book is operable to transmit its unique identifier in an information packet and receive information packets from other poll books. Each poll book arranges the transmitted and received unique identifiers in order according to a predetermined ordering scheme, and establishes communication with two other poll books and exchanges voter database information to ensure all databases have updated information. With the communication established as described, the poll books form a ring network and database information is propagated from poll book to poll book to synchronize the databases between all of the poll books.

receive a plurality of information packets comprising said unique identifiers of other of said poll books communicating over said network;
arrange said transmitted and received unique identifiers according to a predetermined ordering scheme;
establish communication with at least one other poll book based on said ordered unique identifiers; and
exchange voter record information with said at least one other poll book and update said database with data received from said at least one other poll book to synchronize said poll book databases.
13. The system of claim 12 , wherein said unique identifier comprises an IP address of said electronic poll book.
14. The system of claim 12 , wherein said ordering scheme comprises a list of said unique identifiers in numerical order and wherein communication is established with two other poll books corresponding to the next higher and next lower unique identifiers in said list.
15. The system of claim 12 , wherein said information packet is a UDP broadcast packet.
16. The system of claim 15 , wherein said UDP broadcast packet is assigned to a pre-defined port.
17. The system of claim 12 , wherein said communication is established using a TCP/IP connection on a pre-defined port.
18. The system of claim 12 , wherein said exchange occurs at predetermined time intervals.
19. The system of claim 12 , wherein said exchange occurs upon detection of a change in said voter record information in said database.
20. The system of claim 12 , wherein said voter record information comprises poll status, device status, ballot issued status, ballot cancelled status, voter status, and combinations thereof.
21. The system of claim 12 , further comprising:
a central database in communication with at least one of said poll books, said central database operable to receive voter record information from at least one of said electronic poll books to provide backup storage of said information.
22. The system of claim 21 , wherein said central database contains voter records for all registered voters in a jurisdiction.
