INTERNET-MARKs: Clear, Secure, and Portable Visual Marks for the Cyber Worlds

Visual marks play critical roles in the physical world, but their use in the cyber world is limited because there they are easy to forge, tamper with and copy onto unauthorized data. This paper therefore describes a new type of visual marks that are secure because digital signatures are embedded in them and that can be used with a wide variety of cyber-world systems. It also shows the effectiveness of these marks by describing their application to WWW site authentication.
