Progressive Trust

I believe that as we evolve social software to better serve our needs and the needs of the groups that we are involved in, we need to figure out how to apply an understanding of how human groups behave and work. One useful concept I use I call "Progressive Trust". The basic idea is to model how trust works in the real world, between real people, rather then solely relying on mathematical or cryptographic trust.

Post RSA Conference Wrapup

I spent most of last week at the RSA Conference in San Francisco. Like last year, I found little that excited me. I overheard from a convention staffer that they had 30% more attendees, so the conference is growing again, but my week there also reinforced my opinions regarding the industry as a whole as I describe in my previous blog posting The Bad Business of Fear. I asked a number of random people what they thought of the conference.

Security & Cryptography: The Bad Business of Fear

As I head out next week to the RSA Conference I realized that it has been 13 years since I attended the first one. I remember fondly the potential and power of cryptography technology in 1991 -- public keys, digital certificates, new possibilities for privacy, digital cash, etc. After 8 more years I left the compujter security industry on March 15, 1999. The computer security industry also seemed to be filled with as much potential as it did back in 1991.

Confirmed Email Privacy Hole at Orkut

Another Orkut user and I have confirmed a privacy hole in Orkut whenever you send a message to someone via Orkut. For instance, whenever I send a message to anyone in the system that is forwarded by email, in the message headers it will read: From: "Christopher Allen" <member@orkut.com> Reply-To: "Christopher Allen" <christophera@alacritymanagement.com; When someone reads the message in their email software, the "From:" line will be my name but the fake email of <member@orkut.

Insecurity at Orkut

Like many others, I've been paying attention to Orkut in the last couple of weeks. I've answered more requests to be "friends" on Orkut then I have of any of the other half-dozen Social Networking Services I've tried, and I've looking at other people's friends to see if I know anyone. I've yet to ask someone to join Orkut that wasn't already a member, and I've been careful to not have anyone as a "friend" that I didn't know reasonably well and I thought knew me.

Evaluating Social Network Services

After a week where I met a number of bloggers and social network / social software people, I decided to try to update my various networks at Ryze, Tribe.Net, LinkedIn, and Friendster. These are my observations of these social network services after a few weeks of work. Overview of Social Network Services ChristopherA @ Ryze This was the first social network service that I signed up that seemed to already have some of my friends on it.
