  1. OpenID • Brad Fitzpatrick (creator of LiveJournal) argued that the social graph should be shared from one social network site to the next). • Why? • Benefits? • Downsides?

  2. OpenID • Fitzpatrick wrote, "People are getting sick of registering and re-declaring their friends on every site. . . . Developing 'Social Applications' is too much work" (Fitzpatrick and Recordon 2007, "Problem Statement“). • One ID that could be used everywhere would allow people to: • move their profiles and lists of friends from place to • have a single login name that stays consistent from site to site—an OpenID, for example.

  3. OpenID • http://openid.net/ • OpenID • is an open, decentralized standard for authenticating users • can be used for access control, allowing users to log on to different services with the same digital identity where these services trust the authentication body • replaces the common log on process that uses a login-name and a password, by allowing a user to log in once and gain access to the resources of multiple software systems • OpenID authentication is now used and provided by several large websites. Providers include AOL, BBC, Facebook, Google, IBM, Microsoft, MySpace, Orange, PayPal, VeriSign, LiveJournal, Yandex, Ustream and Yahoo! http://venturebeat.com/2009/04/14/single-sign-on-service-openid-getting-more-usage/

  4. OpenID • Surprise! You may already have an OpenID. • If you use any of the following services, you already have your own OpenID. Below are instructions on how to sign in with each of the following providers on an OpenID enabled website. (Where you see bold text, you should replace it with your own username or screenname on that service.)

  5. OpenID – Security concern • Concerns that there is a new “man-in-the-middle” attack possible: • you try to log on to my site using your OpenID with authentication from facebook • Instead of passing your info to facebook, I redirect you to my own server and collect your credentials in a phishing attack • Then I can try various other sites that might accept your OpenID credentials. • Problem with single sign on, in general, is that if your password is compromised once, the attacker has a kind of “master key” to all your OpenID services.

  6. OpenID – is this fair play? • Criticism: Some bigger sites will use their own authentication mechanisms to “issue” OpenID credentials that can be used at other sites, • E.g, you can log onto Yahoo! by getting your credentials verified at Windows Live! • But they won’t accept OpenID sign-ons for their own services. • You cannot use OpenID credentials from elsewhere to log onto Windows Live!

  7. Meta SNSs

  8. Ning • Ning is a personal social networking service – a sort of meta SNS • lets you create your own mini MySpace or LiveJournal or whatever you like - a small social networking platform aimed at whatever niche you want – create entire network instead of just a user profile • users can also join and participate in other networks. • creators can determine their site’s appearance and functionality, as well as whether the site is public or private. • Can include features such as photos or videos, lists of network members and events, groups within the network, and communication tools such as forums or blogs.

  9. Ning

  10. Ning • No technical skill is required to set up a social network, and there are no limits to the number of networks a user can join. • Free to register and use (supported by advertisements), and was adopted as a platform by a lot of businesses and educational organisations • users can pay for premium services that eliminate ads and let users choose network URLs that are separate from the Ning domain. • Ning doesn’t provide statistics or numbers of registered users, but does highlight the number of networks on its platform: April 2008 -> reported 220,000 networks, 70 percent of which were active

  11. Ning • includes networks on broad range of topics including news, current events, professional development, entertainment, dating, support groups, and special interest groups (e.g. “the Christian alternative to MySpace”) • Organizations use Ning to develop a social network that complements their primary website or even as the platform for the organization’s only website • Alumni groups from high schools as well as colleges and universities, use Ning to develop networks where graduates can reconnect and stay in touch. • Touted for a while as the next big thing, but recently Ningannounced that it would become pay only and would cancel its free services. It also fired 40% of its staff.
