Wearable, non-visible identification device for friendly force identification and intruder detection
First Claim
1. A tamperproof identification device comprising:
- an article of clothing;
a user interface mounted on a substrate for entering a passcode and generating an input signal;
a processor mounted on the substrate for receiving the input signal from the user interface and verifying the passcode, and for providing an identification signal to verify the validity of a user of the article of clothing;
a power source coupled to the processor;
a timer coupled to the processor and substrate to determine an elapsed time from the confirmation of the passcode; and
an electrically-sensitive thread for securing the substrate and its coupled components to the article of clothing and coupled to the processor wherein the identification signal is only generated when the processor verifies that the entered passcode is valid and the elapsed time determined by the timer has not exceeded a predetermined time, and the electrically-sensitive thread has not detected tampering.

Abstract
A wearable, non-visible identification device that provides reliable, tamper proof, friendly-force identification and intruder detection. The device is integrated as a part of the wearer'"'"'s uniform and includes a user input surface for periodic entry of a unit- or user-defined pass code. A timeout capability prevents the device and its identification signal from being used if the pass code is not entered within the specified time period. The preferred embodiment uses non-visible optical identification signals for 1-way identification using standard tactical equipment, making the device useful in the field during operations or at temporary security control points away from established bases. Alternative embodiments use radio-frequency, visible and reflective identification signals. All embodiments use identification signaling methods which are effective at safe stand-off distances to minimize the threat to security personnel. The device also supports identification at tactical distances to support identification in the field. Very low cost and low power embodiments for use by security forces in developing nations are described. This invention provides a novel and improved means for defeat of the threat of adversaries or insurgents exploiting stolen or fake uniforms to attack friendly forces.
