Confident Multifactor Authentication is a two-factor authentication service that delivers an image-based authentication option to users mobile phones. The service is set to protect online businesses and their customers from fraud and Zeus-in-the-Mobile (Zitmo) attacks, by securing the second factor and verifying that the legitimate user is in possession of the mobile device.
How it works
When a user first registers with the website or online service, they need to select a few categories of things they can easily remember. In case out-of-band authentication is needed, an application on the users smartphone displays a randomly-generated grid of pictures that has a one-time authentication code encrypted within it.
Then, the user identifies the pictures that fit their previously-chosen, secret categories by tapping the appropriate pictures on the smartphone display. By identifying the correct pictures, the user is reassembling the one-time authentication code that was encrypted within the grid of images.
