Abstract
Systems and methods for improved security by facial micro-expression sequence are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a processor; and a memory coupled to the processor, where the memory includes program instructions store thereon that, upon execution by the processor, cause the IHS to: obtain a video or a series of images of at least a portion of a face of a user of the IHS; determine a sequence of micro-expressions from the video or series of images; compare the determined sequence of micro-expressions to a stored sequence of micro-expressions; and authenticate the user based, at least in part, on the comparison indicating a match.
