Systems, methods, and non-transitory computer-readable media can receive render instructions for rendering an animation. The animation comprises a plurality of layers, each layer comprising one or more layer properties, and a first dynamic property to be defined at runtime prior to rendering the animation. The first dynamic property is mapped to a first set of layer properties of the one or more layer properties. A first dynamic property value is received for the first dynamic property. The first set of layer properties are defined based on the first dynamic property value. The animation is rendered on a computing device based on the render instructions and the first dynamic property value.

Disclosed herein are techniques for face-based user authentication. In one embodiment, a method includes receiving a sequence of image frames captured of a face of a subject, and calculating, for each image frame in a set of image frames from the sequence of image frames, a closity value for the image frame based upon a plurality of angles associated with an eye in the image frame. The closity value calculated for the image frame is indicative of a measure of closeness of the eye in the image frame. The method further includes determining a number of eye blinks occurring in the set of image frames based upon the closity values calculated for the set of image frames, determining liveness of the face of the subject based upon the number of eye blinks, and enabling authentication of the subject based upon the liveness determination.
