Traditionally, publishers and providers of online resources have relied on valid IP address of users in order to authorize access. This turns into a problem when either a subscribing institution does not own fixed and static IP addresses, or when a large portion of access to resources are performed when users are off campus. While initially, the former was a major factor in the development of other mechanisms for authorization, more recently and with the spread of use of smart devices which bring mobility, the latter is a major driving factor for single sign on mechanism.
Single Sign On (SSO) technology is the most advanced tool for identification of authorized users that has made it possible to gain access to all electronic resources of the digital library at any time and place using a unique username and password. This technology has made an enormous change in method and rate of using shared resources.
Using SSO technology, your researchers easily gain access to all electronic information through any internet connection in or out of your library campus. SSO is supported by well known authentication technologies such as Eduserv’s Athens and Shibboleth as well as a large portion of publishing world.
Using SSO, you do not need to have several usernames and passwords to be able to access resources of your digital library.
