Abstract

This paper will discuss the state of the art of optical variable devices (OVDs) as security elements, and the possibilities of fraud-criminals to counterfeit OVDs. The activities of criminals in this field will be reviewed. A few practical cases will be presented, and feasible solutions to protect OVDs against counterfeiting will be proposed.
