Web authentication methods using single sign on method and virtual keyboard

Data security assurance through a web or standalone application implies the development of security technologies and methods. User authentication, a security technology, allows access to data and information only to users which have an account and a password. Besides the well-known passwords users can chose other different authentication methods, i.e. electronic identity cards, smart cards or biometric methods, all of these being possible with some supplementary costs. A Single Sign On authentication method combined with a virtual keyboard represents a secure and efficient solution with low-costs implementation.
