[Privacy] NYTimes: Personal Data for the Taking

http://nytimes.com/2005/05/18/technology/18data.html


[A]ll it takes to obtain reams of personal data is Internet access, a few dollars and some spare time.

Working with a strict requirement to use only legal, public sources of information, groups of three to four students set out to vacuum up not just tidbits on citizens of Baltimore, but whole databases: death records, property tax information, campaign donations, occupational license registries. They then cleaned and linked the databases they had collected, making it possible to enter a single name and generate multiple layers of information on individuals. Each group could spend no more than $50.

...

The Johns Hopkins project was conceived by Aviel D. Rubin, a professor of computer science and the technical director of the Information Security Institute at the university. He has used his graduate courses before to expose weaknesses in electronic voting technology and other aspects of a society that is increasingly dependent on - and at the mercy of - digital technology. "My expectations were that they would be able to find a lot of information, and in fact they did," he said.

...

In some instances, students visited local government offices and filed Freedom of Information Act requests for the data - or simply "asked nicely" - sometimes receiving whole databases on a compact disc. In other cases, they wrote special computer scripts, which they used to pick up whole databases from online sources like Maryland's registry of occupational licenses (barbers, architects, plumbers) or from free commercial address databases like Verizon's SuperPages, an online yellow pages directory.

...

"We feel that open access to public records is key to a free society," said Jason Brandeis, the A.C.L.U. lawyer handling the suit, which seeks to bar Alaska from disseminating contact information for licensed nurses. "But a balance needs to be struck between the public interest in open access to government information, and the need to protect individual privacy."

Whether such a balance can ever be achieved when so much information is already available is an open question. And some people are troubled by recent trends against access.

"I have no problem with an individual who faces unusual threats from publication of her identity or identifying details being able under the law to seek special exception from openness," said Rebecca Daugherty, the director of the Freedom of Information Service Center for the Reporters Committee for Freedom of the Press in Virginia. "But the secrecy should be the exception not the rule."

Several Johns Hopkins students came to a similar conclusion. Despite their surprise at the number of records they could amass and combine, many still felt that the benefits of openness outweighed the risks.

"If some citizen is concerned about dead people remaining registered to vote, he can simply obtain the database of deaths and the voter registration database and cross-correlate," said 21-year-old Joshua Mason, whose group discovered 1,500 dead people listed as active registered voters. Fifty of those dead people somehow voted in the last election.

"The problem is, we don't know what we want," Dr. Rubin said, referring to the competing social interests in openness and privacy.

"It is clear that there are strong negative consequences to being able to collect and correlate all this information on people," he said, "but it is also possible that the consequences to personal freedom would be worse if it were outlawed."

How to Fix a Jammed Toyota Camry Trunk

This problem needs a higher pagerank, so I figured I would post the solution here. If your Toyota Camry trunk won't open, one possible reason is that it is set to valet mode. Valet mode means that you cannot open the trunk using the release lever inside the car. To set valet mode, you put the key into the trunk lock and turn it counterclockwise. You will know that your trunk is in valet mode if the lock is horizontal rather than vertical, and if you cannot open the trunk using the lever near the driver's seat. Of course, a problem is that sometimes the Camry can get stuck in valet mode, such that you can't use your key to get out of it. (You can see how I spent part of my Sunday morning ...) The solution turns out to be WD-40 . Spray some WD-40 on your key and on the lock. Put the key in, and jiggle it around, and happiness ensues. From an interaction design perspective, it sort of makes sense to have a valet mode. After all, the point of having a valet key is to limit the

Web 2.0 and Research

I've been chatting with many of my friends and colleagues about an issue that's been bugging me for a while, namely whether academic research has any role to play in the emerging Web 2.0 . I've been slowly coming to the conclusion that the answer is not much. I had a similar discussion with other researchers at HotMobile a few weeks ago. When the web first came out, pretty much every systems researcher ignored it because it was so ugly. The web was not very sophisticated in terms of distributed systems, HTTP lacked elegance, HTML conflated many different ideas, and so on. There were also not any really new ideas with the web, as evidenced by the fact that Tim Berners-Lee 's first paper on the Web was (probably rightfully) rejected from an ACM conference on hypertext. I'm sure one thing that really irked researchers about the nascent web was that it completely ignored the large body of work in hypertext and distributed systems that had preceded it. Even in 1997, as

[Research] Famous Rejected Papers

I've always thought it would be fun to compile a list of famous rejected research papers, ones that later turned out to be highly influential. For example, in My Life as a Quant , the author tells the story of how the famous Black-Scholes paper (which describes how options should be priced) was rejected several times. The work eventually led to a Nobel Prize in economics. (Yes, I know, there technically is no Nobel Prize in economics). Then there's George Akerlof 's work on asymmetric information . I don't recall exactly, but I think the reviewers thought it was too simplistic. It also led to a Nobel Prize in econ. And then there's Tim Berners-Lee 's original paper on the World Wide Web. He describes his experiences in his book Weaving the Web . I think it was submitted to a hypertext conference, but was accepted only as a demo. I'm guessing reviewers didn't see much novelty in the work, which probably was correct from a research perspective.
