Biometrics refers to technologies for measuring and analysing human body characteristics in person authenticationudapplications. The computational power available in today’s computer and embedded systems (e.g. mobile phones, ludaptop and personal digital assistant) allows the biometrics market to grow with the aim of replacing PIN codes orudtaped password in control access. Among the different biometric technologies that have emerged in the last decade,udautomatic iris verification systems are recognised as the most reliable. This paper presents firstly a new iris verificationudalgorithm based on the concept of Emergent Frequency Demodulation (EMD). The emergent frequency information isudrelated to the Hilbert transform and it is used to extract discriminative features from iris texture. This is followed by audsoftware implementation of the proposed EMD-based iris images processing on ARM920T core-module whichuddemonstrates the feasibility of embedding the iris technology on future multimedia mobile platform.
