An innovative context-aware multi-factor authentication scheme based on a dynamic PIN is presented. The scheme is based on graphical passwords where a challenge is dynamically produced based on contextual factors and client device constraints while balancing security assurance and usability. The approach utilizes a new methodology where the cryptographic transformation used to produce the Dynamic PIN changes dynamically based on the user input, history of authentications, and available authentication factors at the client device.
