Security plays a prominent role now days in preventing the unauthenticated users to access the confidential data. To overwhelm the problems of existing technologies related with security issues a new concept i.e. Iris technology was proposed. So iris technology has resolved all the problems that are allied with the imperfections in the existing technologies used for authentication. In this paper, the authors propose a new idea regarding the iris recognition based on wavelet demodulation technique. The iris that is externally visible is encoded into a sequence of 2D wavelet coefficients that produce iris code.
