Claim 0:
1. A computer-implemented method for movement-based signature authentication, comprising:
detecting and tracking, by a point of sale (POS) terminal, via one or more depth sensors configured to project patterns of infrared light on a user and one or more image sensors configured to capture images of the user within the infrared light range and then generate one or more two-dimensional (2D) images and one or more three-dimensional (3D) images, wherein one or more features associated with the user is detected from the one or more 2D images of the user, and wherein the one or more detected features include facial features and biometric data of the user;
detecting and tracking, by a user movement signature authentication server utilizing a trained machine learning model, one or more body points associated with the user based on the one or more 3D images of the user, wherein the trained machine learning model is continuously updated as training data becomes available;
determining, by the user movement signature authentication server, a movement pattern by connecting a particular body point identified from a first pose of the user to corresponding body points identified from other sequences of poses of the user;
generating, by the user movement signature authentication server utilizing the trained machine learning model, digital representations of lines that link the connected body points between the first pose and the other sequences of poses of the user;
comparing, by the user movement signature authentication server, the one or more detected features to corresponding one or more stored features and biometric data associated with the user, wherein the stored biometric data include facial features and body measurements of the user, and wherein the body measurements include height and/or body segment lengths of the user;
upon determining that the one or more detected features match the one or more stored features and the biometric data associated with the user, comparing, by the user movement signature authentication server, the one or more determined movement patterns to a unique electronic signature associated with the user, wherein the unique electronic signature is a set of expected movement patterns of the user; and
upon determining that the one or more determined movement patterns match the unique electronic signature associated with the user, authenticating, by the user movement signature authentication server, the user for an electronic transaction.
