摘      要：Most remote systems require user authentication to access ***-based passwords are still widely used as a standard method of user *** conventional text-based passwords are rather hard to remember,users often write their passwords down in order to compromise *** of the most complex challenges users may face is posting sensitive data on external data centers that are accessible to others and do not be controlled directly by *** user authentication methods have recently been proposed to verify the user ***,the fundamental limitation of a graphi-cal password is that it must have a colorful and rich image to provide an adequate password space to maintain security,and when the user clicks and inputs a pass-word between two possible grids,the fault tolerance is adjusted to avoid this *** paper proposes an enhanced graphical authentication scheme,which comprises benefits over both recognition and recall-based graphical techniques besides image *** combination of graphical authentication and steganography technologies reduces the amount of sensitive data shared between users and service providers and improves the security of user *** evaluate the effectiveness of the proposed scheme,peak signal-to-noise ratio and mean squared error parameters have been used.
