The paper holding a presentation of a system, which is recognizing peoples through their iris print and that by using Linear Discriminant Analysis method. Which is characterized by the classification of a set of things in groups, these groups are observing a group the features that describe the thing, and is characterized by finding a relationship which give rise to differences in the dimensions of the iris image data from different varieties, and differences between the images in the same class and are less. This Prototype proves a high efficiency on the process of classifying the patterns, the algorithms was applied and tested on MMU database, and it gives good results with a ratio reaching up to 74%.
