Social Media & Preemptive IT Security

In an episode of 2006’s the Masters of Science Fiction television series, called “Watchbird,” flying devices similar to our Predator drones (Unmanned Aerial Vehicles, or UAVs) are programmed with an algorithm that allows them to detect the intent of the an assailant. By doing so, the drones can act preemptively. As long as the Watchbirds were only being deployed away from our shores, everyone lauded their performance. When they were brought home to fight domestic crime, of course, things went awry.


Preemption is always a tricky business that harms innocents and dirties the hands of those who are placed in charge of its deployment, whether the dilemma is war or criminal justice. Now in our colleges we are somewhat unconsciously bringing the concept to education by imposing preemptive information technology security on many of our computer systems and restricting the use of those systems.


On the one hand, we have those who believe that security online must trump everything we do or attempt to do online. Regulations from federal (FERPA) and state laws are frequently interpreted in ways that seem to suggest that we need tight control of online security. On the other, we have those who like me believe that social media, open source software, email, and other Internet tools are so valuable that the occasional difficulties we suffer are simply the cost of doing business in the Information Age. Obviously, we need to comply with all laws but I remind my colleagues that these laws were not created recently and thus not with technologies in mind. Just as obviously, a system that prevents the use of social media, blocks the downloading of Internet materials, restricts the use of email to internal official business, locks out non educational web sites, allows only established database access, and allows only a small amount of designated users is extremely secure. This kind of locked-down system, however, fails us by ignoring our mission, educating our students. If we are not using all the relevant tools at our disposal to educate our students then we are failing our society and undoing hundreds of years worth of progress in education. When we know that our society demands a better educated workforce, when we know that this means educating young and old as well as extending the education of many already in the workforce, how can we in good faith think so preemptively? If we continue down this path, of course, things will go awry.

Linked Data fo the Future of Student Research

I encourage everyone to view Hans Rosling’s amazing presentations, this one showing his new insights into world poverty and life made in Monterey, California in 2007. His worked exemplifies the kinds for presentations that should be available to everyone via the web if Tim Berners-Lee’s Linked Data becomes a reality. Currently, you can find all sorts of data on the web but information you can use is not so readily available. His idea is that everything, not just the conventional web pages, should have an address. For example, there should be a page containing data about you as an individual not just your pictures, games, and random thoughts but real data with statistics. This could contain the places you have lived, your credentials, work progress, earnings, family information, etc. but further those individual pieces of information should be available with or without information about you. Being able to disaggregate this data from your page allows anyone to create on the web or from the web information about the average credentials of people in your state, how people of your ethnicity move through jobs, etc.

The implications for educators are that we can our students get useful data on the web. Perhaps without subscriptions to specialized databases our students can get relevant, accurate, and reputable data. Perhaps we then shift from discouraging research on the web general to teaching our students how to select the most appropriate data for their work.

Currently, Linked data has a PR problem. Berners-Lee who is always visionary is not always the best candidate to express his own vision. He has expressed the concept at several venues over the last couple of years but so few organizations and individuals understand and have embraced the concept. Berners-Lee stated that his employer ignored his idea for hypertext markup language. We cannot afford to miss what he is saying now.
