BitTorrent Monitoring Report

On Tuesday the web was overrun with reports that BitTorrent users are being monitored by a host of different (and in some cases unknown) organizations. I would like to take a quick look at the actual document that spawned these headlines.

BitTorrent logoThe news is takes from a paper presented this week at the SecureComm conference in Italy by Tom Chothia and colleagues at the University of Birmingham.

The paper is free to read here.

All alarmism aside the paper looks at both indirect and direct monitoring techniques, the indirect being the type that is typically used to “catch” people who are illegally downloading films, music and other copyrighted materials, and the more expensive but precise direct means that various companies are employing.

In the paper the authors state that their contribution to the argument can be summed up as follows:

We determine that indirect monitoring is still in use against BitTorrent users and devise more effective techniques to detect peers engaging in it;

We find indications that certain entities engage in direct monitoring of BitTorrent users and provide features to detect such peers;

We also notice that direct monitoring, in its current form, falls short of providing conclusive evidence of copyright infringement.

This is a complex and technical paper, but certain things are noteworthy. The direct monitoring consists in creating false peers that connect to your IP address and monitor its use, be that downloading updates for Linux or watching War Horse.

A user is much more likely to be directly monitored if they are partaking in one of the top 100 objects for download, and in 40% of cases monitoring began within 3 hours of connection. The less popular the object for download, the longer it takes to become monitored. This suggests that those doing the monitoring (be they copyright authorities or private data collecting companies) spend more resources on popular downloads.

One thing I can take from this paper is that somebody is collecting an awful lot of data about a lot of people and their downloading habits, and I wonder why? And also what do they intend to do with it? Particularly as many lawyers deem the data collected as not strong enough evidence to use in a court of law.

Fun With Faces

If you are looking for a little light entertainment on the web this week I may have a couple of sites for you. Both are related to the way you look, and at how others look at you, and you can participate too.

The first site is called All Look Same. The site contains a type of quiz. You are shown photos of people, places, art etc and you have to decide whether they are from China, Japan of Korea. At the end of the test you are given your result with the appropriate advice regarding learning about other cultures.

The exam room contains 8 different categories, from food to architecture, urban scenery, traditional architecture and modern art, but the really fun one is faces. Can you tell the difference between a Japanese face and that of a person from Korea? Take the test to find out.

Korean, Japanese or Chinese?

Korean, Japanese or Chinese?

There are also a couple of sections of holiday photos that really give a run out to your perception neurons.

The second website is somewhat related as it too deals with faces. The Facity site grew out of a project based in Berlin and Tel Aviv, and now covers a multitude of cities. The idea is simple, a series of photos of faces from an individual city, so why not play a game with your friends, show them a page of faces and try to guess the city.

First you can play with your friends, and then why not participate? There are specifications for the photos but the only rule about joining in is that you must live in the city in question, and there are already 100 cities involved.

The list of cities is interesting because it really shows how communication takes place. The faces tend to be clustered, as I presume groups of friends get together and take the photos and then upload them. Milan has hundreds, as do Berlin and Istanbul, but London only has one, miles behind the mighty city of Robbinsville in New Jersey and Targu Mures in Romania.

Faces of women

Average faces for women around the world

Check out the average face section too, as in the photo above of average women’s faces created through a process of comparing single points in many photos, an interesting project I would say.

So why not add your own? Tell them that Technology Bloggers sent you.

Texting While Driving

Communication, communication, communication, but at what cost? In many countries it is illegal to use the phone while driving the car, but many people still do so. Maybe using the phone doesn’t seem such a risky thing to do, but texting?

Figures suggest that many accidents are caused by texting drivers, and many companies are offering possible solutions to the problem. Some Apps block phones that are moving through their GPS systems, but this also blocks passenger phones and cannot tell when the owner is on a bus or train, so have override options. Maybe this override option would be attempted while driving however, and that might be dangerous.

A somewhat typical sight?

Other systems make it so difficult to access the texting facility that it would be impossible to use while driving. Well this is all well and good but a teenager that NEEDS to send a text will find a way, and persistence might not be a good thing at this point. The more difficult it is to enter then the more concentration required, and probably more accidents and deaths caused.

Many of the systems available today also require downloading, so they only work in the phone that carries the App. These systems only work if somebody has downloaded it into a phone (typically their teenage son or daughter’s) and the user cannot work out how to disable it, or doesn’t have another phone or friends for just such emergencies.

More sophisticated systems plug directly into the car and broadcast directly to the driver’s seat, but here hardware is required and other problems of system compatibility are raised.

Although I make light of the situation we are addressing an extremely serious issue. If behaviour does not change than these systems may actually put more people at risk, and that is obviously not to anyone’s advantage.

Many other systems that read out text messages or allow you to dictate them are also available, but I am raising a finger at systems that aim to prohibit rather than adapt behaviour, sold to worried parents that think they might be able to stop their children doing something, and not at those that are aimed at responsible drivers.

So does anybody have experience either as a parent or teenage user that they would like to share with the community?
