A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is one of techniques used to identify people and gives the most accurate and secure means of biometric identification. The biometric authentication technique is based on the pattern of the human iris. This makes the technology very useful in areas such as information security, physical access security, ATMs and airport security with the increasing need of the biometric systems there is the need of large databases of iris images. If required storage space is not adequate for these images, compression is an alternative. It allows a reduction in the space needed to store these iris images, although it may the cost of some amount of information lost in the process and therefore the solution is Image Compression.
