« WYSIYN - Build your own social networks | Main | Bayesian Models of Social Networks and Text with Application to Political, Legal and Bibliometric Data »
1 March 2007
I just taught a segment in David Lazer's Social Networking class at Harvard on how people can analyze and visualize their social networks. David invited the whole class to join him on LinkedIn and we noticed that a couple of students were hesitant to join due to security concerns. We have a very mixed audience of MPP, MPA, Midcareer and PhD students from all kinds of different industries - some of them from the military and security area. One of the students asked me: "Can you give me one good reason why I should join any of the social networking sites?" - given the background and affiliations of some of the students, I couldn't come up with an argument why people should join - on the contrary I understand that some people need to keep a low public profile, so that not too much of their private information or details about their CV will become publicly available.
So I started to think about what are reasons why I have all my information uploaded to all kinds of websites? I have a Flickr page, an openBC/Xing profile, a LinkedIn profile, a personal website, a corporate website and post on my own blog and on our blog at the Kennedy School. Am I too open to give away this much information? On the other hand, I am not working in the military or security area, right?
It turns out that there are ways to control what people can find out about you. I talked with Bill Liao, the co-founder of Xing (formerly openBC) about this issue and he pointed me to the people finder search engine ZoomInfo. It is a search engine that gives summaries of people (Find tab) or let's you create a more detailed profile online, so that recruiters, etc. can find you easier (BeFound tab). Controlling what you actually want other people to find about you comes with a price: pro version for $49/month. But it is definitely one way to control what information can be found about you and also a way to manipulate your online information.
I tried it and was surprised about the result (Remember, I have a at least seven different pages directly connected with my name where I actively produce content). Here is the result:
So there are four entries - one with the direct link to my Kennedy School subpage, but the others are from older sources tracking some of my (past) academic activities. That's about it. Google on the other hand finds 13.200 different entries.
Another way of controlling what is found by Archive.com or Google seems to be to ask thems to take down some of your indexed information and not display it when people search for your name.
What are your thoughts on the dangers of having your information publicly available on social networking platforms? Are there any measures you take to avoid having too much information available for the rest of the world?
(hm... guess I just created another piece of publicly available information)

Good point you make here. Also I have a couple of friends, contacts, and colleagues who are reluctant to publish their profiles online. Most of them though use the "not visible" option so that their contacts cannot be seen (in LinkedIn for instance).
However, I think that it is very difficult today not to let the world know who you are and what you. As soon as you are starting to internetwork which means browsing the web, publishing articles, answering posts, participating in the blogsphere, and being members of several social networking site I do not see any reasonable way of how you can "hide".
From a more practical "data analysis" standpoint I have two points here:
- Yes, it is indeed easy to find out information about a certain person when you have a name, but
- from our social network analysis perspective we know that network sampling is a very delicate task which makes it difficult to draw network analytic conclusions from all the profiles on, say, one or two social network sites
Hence, what I want to say is that there are indeed security/privacy issues here, but since one leaves so many traces in the WWW anyway I find it difficult to say how this could be prevented.
