Yesterday discovered a new concept, called OAuth, OpenSSO in support of this thing is like something Google is providing the API, the original source OpenSSO there this directory, see, not too concerned about turned out to be a protocol name, a typical scenario where a user visits a Web site to another Web site data, such as import gmail contacts to the 163 mailbox. Found that this concept is that last night saw a video on youtube, is a university undergraduate in Taiwan where mentioned, the course is about Google AppEngine and Web 2.0 security, which referred to the SSO, OAuth, OpenID, etc. These things, then think again about our universities. . . Gap Yeah!
