WebID

WebID gives one way to log in to an internet service. Instead of using a password, for example, the member refers to another web address which can vouch for it. WebID is not a specific service or product. Instead WebID is a suggested method for internet services and members to know who they are communicating with. Technically speaking, The WebID specifications define a set of proposed standards for Identity, identification and authentication on HTTP based networks.
