The Long Tail
The Long Tail
For the Economists
The 80% tail matters
Virtual shelf space is limitless
quot;We sold more books today that didn't sell at
all yesterday than we sold today of all the
books that did sell yesterday.quot;

For Everyone Else
Mass social networks vs. niché social
networks

Delivered content vs. discovered content

What is OpenID?
Single sign-on for the web
Simple and light-weight
(not going to replace your bank card pin)
Easy to use and deploy
Built upon proven existing technologies
(DNS, HTTP, SSL/TLS, Diffie-Hellman)
Decentralized
(no single point of failure in the protocol)
Free!
An OpenID is a URI
URLs are globally unique
and ubiquitous
OpenID allows proving
ownership of an URI
People already have
identity at URLs via
blogs, photos, MySpace,
FaceBook, DAUM, etc
Problems it Solves
Too many usernames and passwords
or the lack of different passwords
Someone took my desired username
My online profile is spread across the
Internet without my control
and I can't benefit from it when I go
somewhere new
Account management is hard to do right
How Does it Work?
My OpenID
quot;openid.serverquot; points to my OpenID Provider
1. Site fetches the HTML of my OpenID
2. Finds quot;openid.serverquot;
3. Establishes a shared secret with the
Provider
4. Redirects my browser to the Provider
where I authenticate and allow the OpenID
login
5. Provider redirects my browser back to the
site with an OpenID response
6. Site verifies the signature and logs me in

Security and Trust
Protocol Security
Use SSL correctly throughout the protocol
Protects against man-in-the-middle and
eavesdropping attacks
Generate strong MAC keys and re-negotiate
as needed
Used to verify data integrity and authenticity of
OpenID responses
Verify NONCEs
Protects against replay attacks
Trust
quot;Trust first requires identityquot; - Brad Fitzpatrick
OpenID does not tell you if a user
is good, bad, or even human
Challenge them via a CAPTCHA or
email verification
Use whitelists and blacklists
Ask someone else whom you trust
