Internet Identity and Conspiracy 101

Tuesday, January 27th, 2009

Recently, I’ve started to work on the problem of sybil attacks in mobile nets, and I came across this old discussion on identities in the Internet. The Snakes of Medusa and Cyberspace: Internet identity subversion.

Online Identity

Wednesday, November 21st, 2007

I was reading this interesting article on comment trolling on blogs. It breaks down people order generic cialis who comment on blogs into three categories; those who read and comment with something useful to say, those who “spam”-comment, hoping to generate traffic for their own web sites, and the trolls: those who comment to criticise/put down both the content and the authors (luckily (?) it seems that mobblog has very few of the first category and no trolls!). The interesting thing about the article was the pointer to this other one, which explains that this destructive behaviour may be explained by the lack of online identiy. Here is a quote from the article: (more…)

Anonymous Nicknames vs. Real Identities in Reputation Systems

Friday, February 9th, 2007

“MySpace has been talking to eBay for several months about ways they could partner on what MySpace calls “peer commerce,” according to people familiar with the matter. The idea is to let MySpace users buy and sell items from each other using eBay’s online-commerce technology and its PayPal payment system, these people said. MySpace users would be able to post items for sale on their profiles, and their eBay auctions would be automatically updated, according to one person close to the discussion”.

Portable Reputations

Friday, January 19th, 2007

In UTIFORO (a new research project), we may explore how sellers may “port” their reputation from eBay to informal markets. That might relate to this:
Last year I mentioned eBay’s Feedback system and said it was arguably their biggest asset. Even with its flaws, I said, it is one the biggest drivers of trust between two people buying and selling who’ve never met and never will. But it’s a closed system, usable only within eBay and only for eBay transactions.
We needed an internet-wide identity and feedback system that any reputable application can tap into, both pulling and pushing data.
At the time we had taken a look at iKarma, but they seemed to have missed the boat by ignoring the portability aspect of reputation.
Rapleaf launched in April. And while it’s still quite early, it does exactly what we need it to do – provide a good off-ebay reputation system. eBay banned Rapleaf in May (They learned their lesson with PayPal it seems), but the company is still chugging along.
