Iris, Face and Sound Recognition Biometrics

Iris recognition is the process of recognizing a person by analyzing the random pattern of the iris. The automated method of iris recognition is relatively young, existing in patent since only 1994. The iris is a muscle within the eye that regulates the size of the pupil, controlling the amount of light that enters the eye while Voice Recognition is as distinct as a human's face image or fingerprints. The popularity of diverse communication means (landline and cell phones, Internet phones, etc.) open a wide number of opportunities for the application of voice recognition technology. In addition, identifying humans by their voices is both user-friendly and effortless.
