1. A method for maintaining user movement tracking using non-identifiable biometrics, comprising:
determining, via a computer vision system, an identity of a user using a set of facial features, wherein determining the identity of the user comprises:
storing, in a computer memory, a last sampled image comprising the set of facial features; and
updating, with the last sampled image, a human landmark tracking index comprising:
a user identification (ID) indicative of the identity of the user;
a frame location for the set of facial features in the last sampled image; and
a frame location for a secondary human landmark;
associating the set of facial features with a head and the secondary human landmark that does not include the set of facial features;
determining that the set of facial features is unlocatable by the computer vision system; and
tracking the user, via the computer vision system, using the head and the secondary human landmark that does not include the set of facial features.
