U.S. Patent #6,947,978:
Method for geolocating logical network addresses
Abstract: Method for geolocating logical network addresses on electronically switched dynamic communications networks, such as the Internet, using the time latency of communications to and from the logical network address to determine its location. Minimum round-trip communications latency is measured between numerous stations on the network and known network addressed equipment to form a network latency topology map. Minimum round-trip communications latency is also measured between the stations and the logical network address to be geolocated. The resulting set of minimum round-trip communications latencies is then correlated with the network latency topology map to determine the location of the network address to be geolocated.
“Fact Sheet NSA Suite B Cryptography“:
The entire suite of cryptographic algorithms is intended to protect both classified and unclassified national security systems and information. Because Suite B is a also subset of the cryptographic algorithms approved by the National Institute of Standards, Suite B is also suitable for use throughout government. NSA’s goal in presenting Suite B is to provide industry with a common set of cryptographic algorithms that they can use to create products that meet the needs of the widest range of US Government (USG) needs.
“The Case for Elliptic Curve Cryptography“:
Elliptic Curve Cryptography provides greater security and more efficient performance than the first generation public key techniques (RSA and Diffie-Hellman) now in use. As vendors look to upgrade their systems they should seriously consider the elliptic curve alternative for the computational and bandwidth advantages they offer at comparable security.

Salon has an interesting article about parents turning to technology to monitor their children, instead of to other people in their community.
“What is happening is that parents now assume the worst possible outcome, rather than seeing other adults as their allies,” says Frank Furedi, a professor of sociology at England’s University of Kent and the author of “Paranoid Parenting.” “You never hear stories about asking neighbors to care for kids or coming together as community. Instead we become insular, privatized communities, and look for
technological solutions to what are really social problems.” Indeed, while our parents’ generation was taught to “honor thy neighbor,” the mantra for today’s kids is “stranger danger,” and the message is clear — expect the worst of anyone unfamiliar — anywhere, and at any time.
This is security based on fear, not reason. And I think people who act this way make their families less safe.
EDITED TO ADD: Here’s a link to the book Paranoid Parenting.

Your cell phone company knows where you are all the time. (Well, it knows where your phone is whenever it’s on.) Turns out there’s a lot of information to be mined in that data.
Eagle’s Realty Mining project logged 350,000 hours of data over nine months about the location, proximity, activity and communication of volunteers, and was quickly able to guess whether two people were friends or just co-workers….
He and his team were able to create detailed views of life at the Media Lab, by observing how late people stayed at the lab, when they called one another and how much sleep students got.
Given enough data, Eagle’s algorithms were able to predict what people — especially professors and Media Lab employees — would do next and be right up to 85 percent of the time.
This is worrisome from a number of angles: government surveillance, corporate surveillance for marketing purposes, criminal surveillance. I am not mollified by this comment:
People should not be too concerned about the data trails left by their phone, according to Chris Hoofnagle, associate director of the Electronic Privacy Information Center.
“The location data and billing records is protected by statute, and carriers are under a duty of confidentiality to protect it,” Hoofnagle said.
We’re building an infrastructure of surveillance as a side effect of the convenience of carrying our cell phones everywhere.

More stupid security from our government. From an AP story:
President Bush has ordered plans for temporarily disabling the U.S. network of global positioning satellites during a national crisis to prevent terrorists from using the navigational technology, the White House said Wednesday.
During a national crisis, GPS technology will help the good guys far more than it will help the bad guys. Disabling the system will almost certainly do much more harm than good.
This reminds me of comments after the Madrid bombings that we should develop ways to shut down the cell phone network after a terrorist attack. (The Madrid bombs were detonated using cell phones, although not by calling cell phones attached to the bombs.) After a terrorist attack, cell phones are critical to both rescue workers and survivors.
All technology has good and bad uses — automobiles, telephones, cryptography, etc. For the most part, you have to accept the bad uses if you want the good uses. This is okay, because the good guys far outnumber the bad guys, and the good uses far outnumber the bad ones.

The armored Mercedes belonging to the CEO of DaimlerChrysler has been stolen:
The black company car, which is worth about 800,000 euros ($1 million), disappeared on the night of Oct. 26, police spokesman Klaus-Peter Arand said in a telephone interview. The limousine, which sports a 12-cylinder engine and is equipped with a broadcasting device to help retrieve the car, hasn’t yet been found, the police said.
There are two types of thieves, whether they be car thieves or otherwise. First, there are the thieves that want a car, any car. And second, there are the thieves that want one particular car. Against the first type, any security measure that makes your car harder to steal than the car next to it is good enough. Against the second type, even a sophisticated GPS tracking system might not be enough.
