Abstract

A method for authenticating a user of a computing device. The method includes a computer processor receiving an indication that a user of a computing device is accessing an object that utilizes an authentication process. The method further includes a computer processor selecting a first multi-media file that is associated with a user profile of the user and the object of the authentication process, wherein the first multi-media file is associated with a baseline user input authentication sequence. The method further includes creating a first temporal manipulation vector based on the user profile and a security requirement of the object of the authentication process, wherein the temporal manipulation vector modifies a presentation of a multi-media file and a corresponding time sequence of a user input authentication sequence in the multi-media file. The method further includes transmitting the first temporal manipulation vector and the first multi-media file to the computing device.
