Dynamic iris biometry: a technique for enhanced identification
BMC Research Notes, 2010 Background The iris as a unique identifier is predicated on the assumption that the iris image does not alter. This does not consider the fact that the iris changes in response to certain external factors including medication, disease, surgery as well as
