1. A method ( 200 ) of identifying a person implemented by using an acquisition device ( 150 ) and comprising: (a) a step ( 202 ) of capturing an image of the iris ( 102 ) or irises ( 102 ) of the person through optical deformation means ( 160 ) by the acquisition device ( 150 ) which effects an anamorphic transformation of the image of the iris ( 102 ) or irises ( 102 ) along a first axis that passes through the centers of the two irises ( 102 ) of the person and along a second axis perpendicular to the first axis; (b) a step ( 204 ) of processing the image thus captured so as to code it in the form of one or two models; (c) a step ( 206 ) of comparing the model or models thus obtained with reference models contained in storage means ( 156 ); and (d) a decision-taking step ( 208 ) concerning the identity of the person from the result of the comparison step ( 206 ).
