Facebook and Privacy Issues: Reflections about the ever-changing interfaces of Facebook and the growing number of Facebook-connected websites.....
I first joined Facebook in 2007 when I was taking a graduate HCI-oriented course about privacy and security. Heather Lipford, the professor, and some of my classmates were working on a study about Facebook and privacy, so I agreed to participate as a subject. What I quickly learned is that even graduate IT students can be puzzled about Facebook privacy settings. Facebook has made numerous changes to the way it handles privacy settings, and this has fueled research on this topic for the past few years (see links below).
Too many "regular" folks are unknowingly sharing things they do not want to share with the world, and it is difficult for most of us, including myself, to keep up with these rapid changes. For example, last month I came across a video of Mark Zuckerburg (founder of Facebook), announcing Open Graph which is a way of making "connected, mapped web that is more "social, personalized, smarter, and semantically aware." Zuckerburg's keynote presentation at the f8 conference was delivered on April 21st, yet on the day I posted about it, only a handful of people had viewed the video.
As of this post, only about 731 people had viewed the presentation, yet the key points that were reviewed will impact how the information we provide Facebook is used, stored, and perhaps shared by third-party web-based applications.
With over 400,000,000 people on Facebook, this is an open invitation for those "in the know" to manipulate things in a way that many of us may not understand.
In the video below, Zuckerburg mentions that Facebook's policy for applications integrated with Facebook prohibited the storage or caching of data and information from the user for more than 24 hours. The rationale for the rule was to protect the privacy of Facebook users.
At about 4:58 in the video, Zuckerburg discusses this policy, and announces that it has been changed. He then goes on to say, "We're going ahead and getting rid of this policy." (5:09) This made the audience very happy (about 5:10):
Zucherburg introduces the "One Step Permission" feature that provides third-party websites a simple means for users who have Facebook accounts to connect with the site. The hitch is that the user can't move forward and access what they'd like to access on the site unless they make the quick decision to give up quite a bit of their Facebook information. This will now give the host application your information, and store it forever, I assume.
Here is a screenshot of the single permissions dialog from the video at about 4:16:
"Now, if a person comes to your site, and gives you permission to access their information, you can store it. That means no more having to make the same API calls day after day. No more having to build different code paths just to handle information that Facebook users are (unwittingly?) sharing with you. We think that this step is going to make building with Facebook platform a lot simpler."
I knew there was a BIG problem with Facebook's privacy settings when Nathan Yau, author of the Flowing Data blog, tweeted about his discovery of information that Facebook somehow shared without his knowledge. Nathan's recent post, "Evolution of Facebook Privacy Policies", contains a interesting visualization, created by Matt McKeon of the Visual Communication Lab at IBM, that provides an interesting look at Facebook's privacy policies from 2005 on.
The Evolution of Privacy on Facebook (Interactive graphic with options for viewing an animation or an image-based version.)
The blue area represents the default settings regarding the availability of your personal data. As you can see, the default settings allow a large set of personal information to be shared among your Facebook connections as well as the outside world. As a member of Facebook, you must manually change your settings to make sure you have your preferred level of privacy. Don't assume this is taken care of for you by the application!

IBM's Visual Communication Lab is behind the Many Eyes website, which I used as a resource during when I was taking a course in information visualization and visual communication. At the time, I was looking at data related to the high-school drop-out problem in the US. I loved how the on-line Many Eyes application provided me with a variety of ways of looking at the data I had collected for my team's project. Since then, thousands of other people have utilized the Many Eyes website. Warning: If you are interested in data, stats, and information visualization, be prepared to spend a while exploring. It is an enticing rabbit hole!

Wrapping my head around f8 and Facebook's OpenGraph: The goal is to create a connected, mapped web that is more "social, personalized, smarter, and semantically aware."
During the mid-2000s I took a few courses related to web-development and internet programming. This was before the twitterfacebookyoutube era. There's a lot of catching up to do.
Today, I'm watching a few videos from the recent f8 conference. It took place on April 21st, 2010 in San Francisco.
So what is f8?
"f8 is a Facebook conference where developers and entrepreneurs collaborate on the future of personalized and social technologies. At f8, members of the Facebook team and the developer community will explore a variety of topics including new tools and techniques, business growth strategies and open technologies." -Facebook
You can find more f8 videos by following the link below:
http://apps.facebook.com/feightlive/
Here are some tidbits of info from the first video:
- The number of people using Facebook via Facebook on mobile devices is rapidly increasing.
- More than 400 million people are on Facebook
- One step permission is now available for developers and users, users will be clear about what permissions they are given.
- New policy allows websites to store Facebook users' permission data beyond the previously imposed 24 limit.
- Facebook is ramping up to handle monitory transactions: See http://developers.facebook.com/credits
- "Open Graph puts people at the center of the web, becoming a set of personally and semantically meaningful connections between people and things".
- Facebook maps out people and relationships of the online "social graph".
- Pandora maps out musics, Yelp, small businesses.
- News websites map out current events and news content
- The goal is to create a connected, mapped web that is more "social, personalized, smarter, and semantically aware."
Microsoft announced Docs.com the day of the f8 conference. The description is in the fourth video. It links with Facebook and was designed to be "social".

News about Smart Grids and Smart Kitchens
Duke Energy has established a Smart Grid in one of the neighborhoods in Charlotte, N.C. So what exactly does a Smart Grid look like? Take a look at the following slideshow:
So what exactly is a Smart Grid? It is a system to support "smarter" ways to manage and use energy, and utilizes intelligent sensors along power lines, communication nodes on utility poles, and Smart Meters at customers' homes. Duke Power has provided customers with home management systems to provide them with "timely energy usage information".
Here's the video:
Smart Grid: Virtual Power Plant
You can have a Smart Grid Kitchen along with your Smart Grid energy service, at least sometime in the near future. The pictures below are from CNET News:
It is networked via WiMax:
It comes with a lot of "stuff", hopefully it can be tastefully hidden or decorated:
I don't see a single woman in the GE Smart Grid Kitchen pictures.

Daily Digital Out of Home post, "Billboards That Look Back" : Could miniature cameras embedded in ads lead to Big Brother at the mall?
Big Brother at the Mall?
If you visit malls, big box retailers, or frequent public spaces, you've probably noticed that there are many digital billboards cropping up. Some are in the form of interactive touch screens and kiosks, and others are in the form of informercials on large displays. What you might not have noticed is that many of these displays have embedded miniature cameras.
I had a chance to see this at a Digital Signage expo not too long ago. I was surprised that the system identified my gender as soon as I stood in front of the display. In my situation, I knew that I was within range of the camera. Out and about, I am not sure if this would be true.
Via Daily Digital Out of Home (dailydooh):
An article in the NY Times recently discussed privacy concerns related to new technology that is embedded into billboards and digital displays. Miniature cameras are embedded in ads found in in malls and other public spaces. The cameras are linked to software that takes in detailed information about the people who come across these ads.
Here is an excerpt from the NY Times:
"Now, some entrepreneurs have introduced technology to solve that problem. They are equipping billboards with tiny cameras that gather details about passers-by — their gender, approximate age and how long they looked at the billboard. These details are transmitted to a central database.
Behind the technology are small start-ups that say they are not storing actual images of the passers-by, so privacy should not be a concern. The cameras, they say, use software to determine that a person is standing in front of a billboard, then analyze facial features (like cheekbone height and the distance between the nose and the chin) to judge the person’s gender and age. So far the companies are not using race as a parameter, but they say that they can and will soon."
"....TruMedia’s technology is an offshoot of surveillance work for the Israeli government. The company, whose slogan is “Every Face Counts,” is testing the cameras in about 30 locations nationwide. One TruMedia client is Adspace Networks, which runs a network of digital screens in shopping malls and is testing the system at malls in Chesterfield, Mo., Winston-Salem, N.C., and Monroeville, Pa. Adspace’s screens show a mix of content, like the top retail deals at the mall that day, and advertisements for DVDs, movies or consumer products."If you are interested in learning more about the business and industry side of interactive off-the-desktop and out-of-home technology, the Digital Out of Home blog is a great resource.

Mobile RFID by Samsung; Open Verizon Network?!
“This is a transformation point in the 20-year history of mass market wireless devices – one which we believe will set the table for the next level of innovation and growth,” said Lowell McAdam, Verizon Wireless president and chief executive officer. “Verizon Wireless is not changing our successful retail model, but rather adding an additional retail option for customers looking for a different wireless experience.”
InformationWeek
Samsung said it expects the radio-frequency identification "We are enabling anytime, anywhere mobile access to information," said Chihee Chung, senior VP of Samsung's Electronics System LSI Division, in a statement. "RFID chip readers systems allow consumers to pull context-specific information into their mobile devices while on the go. Our mobile RFID single-chip technology is an important step in the evolution of ubiquitous computing." My comments: Although Verizon and Samsung's efforts appear to move us closer to Weiser's vision of ubiquitous computing, we must keep in mind that with each advance in technology, there are a host of other problems, such as privacy and security, usability, and accessibility, that remain to be fully addressed!
