We developed a system to coalesce people’s distributed social network personas from across the Internet, then buy and sell shares of people in a
stock market to determine reputation.

You, too, can own your own person!

Caveat•XFN data isn’t clean
•We have to make sure “me” relationships are bidirectional
•We find it acceptable to leave some Identities not fully combined
•Some people use it incorrectly for no readily apparent reason

Other Reputation Systems
•PageRank (Google)
•Windley et al and OpenPrivacy
•Attempting to strip context (e.g., eBay-ness) from context-sensitive reputation (e.g., eBay Feedback Score)

Big Ideas• If you have cool friends, they can make
you cool
• Like PageRank
•No one ultra-cool user can make you cool
•Users have to be invested in the system to make others cool
• Prevents Sybil attack
•No Negative Commentary

Reputation Math•Every value starts at 1
•Every share purchase raises the value by 1
•Every share sale lowers the value by 1
•The purchase price is equal to the value
•An Identity can only own 5 shares of another single Identity
![Page 30: Mnikr - Digital Identity Management 2009](https://reader034.fdocuments.us/reader034/viewer/2022042816/5591166d1a28abf6158b477e/html5/thumbnails/30.jpg)
Reputation Math
•Alice has a share value of 5
•Bob buys one share, which costs him 5
•Alice now has a value of 6
•Bob now sells his share, which gives him 5 points back
•Alice now has a value of 5
![Page 31: Mnikr - Digital Identity Management 2009](https://reader034.fdocuments.us/reader034/viewer/2022042816/5591166d1a28abf6158b477e/html5/thumbnails/31.jpg)
Dividend Math
•Dividends = (value * shares) / 20
•Personal Dividends = value / 5
•So if Alice owns 3 shares of Bob, whose value is 8, then Alice gets (3*8)/20 = 1 point
•Bob also gets 1 point for his value of 8
•Dividends are run every 24 hours
