Identification system based on color sequence and mobile phones

Abstract

This paper describes the application and the suitability of color sensors and mobile devices for the design and development of secure personal identification systems in pervasive environments. The system uses a color sequence properly encrypted and stored on a mobile device to be used as the only identification. An application stored in the phone device is responsible for decrypting and displaying the sequence of colors that is read by a real color sensor that could be connected to any kind of objects in a pervasive scenario. Data structure of the identification key, encriptation type, processing and application of the system is described in this paper.
