HUMAN-RECOGNIZABLE CRYPTOGRAPHIC KEYS

摘要

A visual authentication scheme for websites is provided that binds an image to a website so that a user can by visually authenticate whether he/she is viewing an intended/trusted website. An authentication or cryptographic key (associated with a web page) is rendered as a unique key-identifying image or unique sequence of images. This key-identifying image(s) is then displayed to the user. The user associates this key identifying image with the originator or source of the web page so that the user can easily recognize the originator by glancing at the key-identifying image. The association between the key-identifying image and the cryptographic/authentication key (and thereby the source of the web page) can be achieved similarly to brand awareness.
