The problem of Tailgating/Piggybacking through secure portals is a long standing potential breach in virtually all controlled access portals. Absent a human guard, the access control system is totally dependant on honesty by the authorized users to prevent unauthorized passage when the portal is open for authorized passages. Newton Security has developed a system using stereo machine vision technology to defeat such unauthorized passages. While systems with very high rates of detection coupled with low false alarms have been developed and are currently deployed, further research is necessary to bring the cost of deployment down to facilitate the use of this technology in all doors protected with access control, not just the areas of high sensitivity where the product is currently utilized.
