Significant research into the feasibility of keystroke dynamics as a potential biometric authentication method has taken place since the advent of computers. The studies have progressed from examining typing patterns on desktop keyboards using statistical pattern classifiers to mobile keyboards using neural networks as a pattern classifier. The studies do not have a unifying method of comparing results,...
Internet users today often have usernames and passwords at multiple web sites. To simplify things, many sites support some form of federated identity management, such as OpenID, that enables users to have a single account that allows them to log on to many different sites by authenticating to a single identity provider. Most identity providers perform authentication using a username and password....
User authentication is one of the fundamental procedures to ensure secure communications and share system resources over an insecure public network channel. Especially, the purpose of the one-time password is to make it more difficult to gain unauthorized access to restricted resources. Instead of using the password file as conventional authentication systems, many researchers have devoted to implement...
Biometric recognition systems represent a valid solution to the safety problem of Internet accessibility, even if they do not always provide an environment easily comprehensible by users and operators with a mid-level of competence. This gap can be partially filled if, instead of using the conventional access routines to the authentication system, the user could simply write to the system through...
Current state-of-the art solutions for online banking authentication and identity management include methods for re-authenticating users via out-of-band channels for each transaction. SMS-based schemes belong to this category, and can provide strong authentication to protect against security attacks. Poor usability of these schemes is still a problem, which makes them vulnerable to other obvious attacks...
With the broad application of UNIX and its descendants in recent years, heterogeneous network environment is a must to maximize the enterprise's freedom of choice. However, because of different accounts formats and authentication mechanisms of various operating system (OS), heterogeneous network environment also increases difficulties for system management and security implementation. Facing the situation,...
With the development of grid service, there are two key problems to be improved. One is to access Web grid service with friend interface for user. Another is the security authentication for grid resource share. Nowadays, a solution of Web universal entrance for grid service has been given through a Web framework named grid portal. PKI based grid security infrastructure has been widely used in order...
