RIVA seal system
The Re-useable, In-situ Verifiable, Authenticated Seal System (RIVA) will provide applicable agencies in the US government and in the international arena, with a secure sealing system for a wide variety of applications, including treaty verification, arms control, and international safeguards. The system consists of a number of RIVA fiber-optic seals and a PC-based verification system that is used to initially program each seal, and at a later time, to provide a positive indication as to all the seal's integrity and identity, in a time-related manner. Each re-useable RIVA Seal is based on the concept of continually transmitting, and subsequently receiving, specially encoded message packets over a fiber-optic cable/loop, that may be up to 100 meters in length. The loop is secured to an item of interest in such a way that it is not possible to gain entry into the item without breaching the secure link. Any missing, or suddenly re- occurring fiber-optic messages (due to loop opening or closings) , any message that cannot be verified (due to tampering), or any indication of seal-body tampering, are construed as a seal event anomaly. This event information is immediately stored with the seal, or is transmitted in an authenticated manner, over a wireless RF link, to a remote receiving station for time-tagged storage. Optionally, this data can be passed on to a central data integration center for real-time applications. Three different collection modes provide the inspector with a user-firendly, interactive, menu-driven system that is used during collection periods and provides a method to easily determine when and if the seals integrities have been compromised. 5 refs., 4 figs.
