摘要：Iris templates can be matched using various matching techniques; each approach to iris recognition hasseveral aspects being taken into consideration. One of the most important aspect being the presence of a lens in theusers eye. The biometric templates, including iris and users attributes which are produced by using different recognitiontechniques can be matched through the Iris-templates can be replicated. From this we conclude that, without a thoroughsecurity analysis, iris templates cannot be assumed safe and secure. In this paper, we are going to discuss about thepresence of a contact lens, particularly a colored lens, and the challenges we face as it alters the natural iris patterns. Inthis paper we will use a feature extraction method to remove the effect of colored contact lenses and make it moresecure. This has proven to be very efficient and also less space consuming.
