Apparatus and method for a system capable of remotely validating the identity of individual and their location
First Claim
1. A system for remotely validating the identity of an individual, comprising:
- a first device including first number generating means for generating a first sequence of numbers and attachment means for attaching the device securely to the individual such that the first device will cease to generate successive numbers in said first sequence if it is removed from the individual;
a second device remote from the first device and including second number generating means for generating a second sequence of numbers and means for comparing said first and second sequences of numbers, andmeans for establishing a remote communication between said first and said second devices in order to communicate the current number in the first sequence to said second device and, if the current number in the first sequence matches the current number in the second sequence, determine that the identity of the individual is valid, further comprising means for causing said first device to alert said individual at pseudorandom time intervals that the individual must initiate contact to said second device within a limited time interval when establishing said remote communication.

Abstract
A system capable of remotely validating the identity of individuals and monitoring their locations includes a first device attached to the individual being monitored by a circumferential band worn around his wrist, ankle or neck that is capable of electronically generating a sequence of pseudorandom numbers that will cease to function if the band is cut or otherwise opened to detach the device from the individual. The system also includes a second device which is a remote microprocessor or computer based monitor synchronized to the same sequence of pseudorandom numbers and in occasional communication with the individual over telephone lines or some other remote means such as a radio frequency transmission link. The system may be used to limit remote access of computer data bases to authorized individuals or to limit entry to facilities such as offices or buildings on a campus. Access is authorized when the individual communicates a current valid pseudorandom number to the central computer-based monitor. The pseudorandom number sequence, which changes in time and cannot be predicted, serves as an access key which will only continue to function if it remains attached to the same individual. The same basic system can also be used to determine an individual'"'"'s location for various purposes, such as electronic monitored house arrest, if the central based computer monitor can establish a telephone number that the individual responds to or if the individual'"'"'s coordinates are established using some ancillary means such as a portable Loran receiver or a Global Positioning Satellite receiver carried by the individual being monitored.

25. A system for remotely validating the identity of an individual, comprising:
-
a first device including first number generating means for generating a first sequence of numbers; a second device remote from the first device and including second number generating means for generating a second sequence of numbers and means for comparing said first and second sequences of numbers; and means for establishing a remote communication between said first and said second devices in order to communicate the current number in the first sequence to said second device and, if the current number in the first sequence matches the current numbers in the second sequence, determine that the identity of the individual is valid, wherein said first device further comprises sound generating means for generating an audio response and means including a button on said first device for initiating generation of said audio response in order to communicate the current number in said first number sequence over a telephone link to said second device during said remote communication. - View Dependent Claims (26, 27)
