Abstract
A technique for authenticating a user is described. During this authentication technique, an electronic device (such as a cellular telephone) captures multiple images of the user while the user moves the electronic device in a pre-defined manner (for example, along a path in 3-dimensional space), and determines positions of the electronic device when the multiple images were captured. Then, the electronic device compares the images at the positions with corresponding pre-existing images of the user captured at different points of view. If the comparisons achieve a match condition, the electronic device authenticates the user. In this way, the authentication technique may be used to prevent successful replay attacks.
