Iris identification technology is a biological characteristic identification technology with the lowest error reception rate and the lowest error refusal rate. It differentiates accuracy from error of identification by collecting iris image, abstracting features and matching features. Because of its commonness, uniqueness, reliability and also anti-interference, this technology has high academic value and very wide future applications. Through the complete analysis of current research situation, identification frame-work, and system component, acquisition and pretreatment of iris image, extraction of features, matching of features and evaluation of performance are discussed, and the problems of this technology, such as the difficulty of acquiring high quality images, and stability and feasibility to be testified are reviewed as well. The direction of further research and development and future application of this technology cover the fusion of iris identification information with other biology identification information and non-biology identification information; set-up of iris identification network system; highly efficient identification calculation and identification chip with commonness and strong compatibility.
