ABSTRACT
Client authentication is an essential component in nearly all electronic payment systems. This provides foundation for client the legal access control and user liability. The most foremost used authentication technique is the textual or traditional alphanumeric password. However, this method suffers several setbacks. For instance, clients usually choose passwords that can be easily guessed, thus, compromising security of the user’s password information. Furthermore, when the password is tough to predict, it will all also be tough to remember. To resolve these challenges highlighted in this context, graphical authentication methods are proposed. Many authentication-based applications including electronic payment systems find the use of graphical password to be robust especially with regards to security and ease of use. Hence, in this research work, a thorough comprehensive analysis is carried out on existing graphical authentication password techniques with keen emphases on their suitability for electronic payment systems. This survey has shown that graphical based password technique would be the most reliable authentication technique for e-payment systems.
