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.
