主权项

1. A method comprising:
receiving an authentication request at a computing device; generating a dynamic visual signal in response to receiving the authentication request, wherein generating the dynamic visual signal comprises modifying at least one image, and modifying the at least one image comprises changing a display location of the at least one image to be different from prior authentications and altering a size of the at least one image, wherein the modifying the at least one image identifies the at least one image out of a plurality of images and suggests an authentication token; displaying the dynamic visual signal at the display location in response to the authentication request; receiving the authentication token in response to displaying the dynamic visual signal, wherein the authentication token changes based on the modifying of the at least one image; and determining whether the authentication token satisfies authentication requirements at the computing device.
