    I wish people would realize that web bugs and cookies ARE NOT THE SAME THING. A bug is a spying device. It does not rely on cookies. It does not rely on images (although they are commonly used.) It does not rely on 1x1 pixel images (which in most cases are NOT used - hell, every banner ad from every banner ad company is a web bug!). JavaScript code, images, frames, shockwave can all be bugs. Why? Because one can create a page (say on server X), with references to ANOTHER server (say Y) containing the objects. So when a person visits the page on server X, server Y gets to know about it.

    Cookies definitely can exasperate the problem by providing additional information. But bugs are not reliant on cookies. You can block all cookies and block all images and you will not block all web bugs. The reason advertising companies like to use cookies is that you can track additional information easily, because the browser obligingly stores the data and spits it back on demand, even after you shut the browser down and start it back up, often hours, days or weeks later.

    For reference, check the Web Bug Report quote in the CNET article and you'll notice that the report shows the types of bugs (imgs, iframes, etc.) that are present. A very large # of them are not images...

Pulled-in scripts where the JS in question doesn't appear in the page source won't work, because browsers enforce cookie-domain rules based on the source of the script, not the page pulling it in.

    As for why the images are small and transparent, let me ask this: if the only purpose of the image is in fact to collect legitimate site statistics, what purpose does it serve to have it taking up more real-estate on the page and more bandwidth on the network than it absolutely has to to do it's job?

    "Any company that uses Web bugs on their site should say so clearly in their privacy policies and explain the following: why they are being used, what data is sent by a bug, who gets the data, and what they are doing with it," he added.

First of all, companies with web sites are (in most countries) legally required to tell you about what kind of data they collect and what they do with it.

I personally think it's a great idea. And it's all well and good for sites that deploy their own web bugs. But what about the web sites who use web bugs belonging to other websites (e.g sites who use DoubleClick web bugs, or Slashdot using a web bug from OSDN)? The application should be the same, of course, but how is that handled from a legal perspective? Who is responsible for the "bug"? The company who wrote/owns it, or the company that deploys it? Answers to any of these questions are more than welcome (particularly by someone involved in the legal profession), as I'm sure that there's at least some of us Slashdot readers that would like to know.

    I have to disagree. There is a very important difference between the info transfer with a Web bug (or equivalent) and just sending around log files behind the scenes. Our FAQ covers this.

    In the scenario I described, OSDN ends up with both cookies. This allows OSDN to synchronize with Slashdot, allowing both sites to realize they're discussing the same user, no matter when the sites originally assigned the cookies, and without planning to synchronize in advance. If on the other hand Slashdot just sends a log file to OSDN, then the synchronization is much harder to achieve, and in practice, would probably not even be attempted.

A web bug is when images are used to do tracking *across sites*. SO like when cnn has an image that sets a cookie from doubleclick, and then doubleclick reads that cookie on msn.

    Slashdot uses an image to do tracking, but from the osdn.com domain. They are part of that network of sites. Therefore, slashdot uses a pretty nifty way of doing tracking, but isn't guilty of "web bugging"

  123. Web bugs = bad name, not so bad tactic by closedpegasus · · Score: 3

    What's the big deal with web bugs, anyway? As long as the tracking that's being done is for use by the site I am visiting, I see no problem with them...it's just a tactic for getting usage statistics about your site. And what's wrong with that? When you go to a store, there are video cameras watching you, and records of your sales, etc...why shouldn't a website know which pages were visited? As long as the information being collected can't be used to uniquely identify me, I see no problem with it. A web bug can't collect any more information than your standard log file, and maybe get access to your cookies. But it can only access cookies *that were set by it in the first place*. Web sites don't have the luxury of talking face to face to everyone who comes to the site, like a retail store does. Somehow, they need to monitor what's going on, and a web bug is one way to do a good job of it. One could easily add the same code the web bug executes to the top of every page...and I don't think there would be any problem with that. Web bugs are just a more elegant solution -- you can abstract out all those tracking functions, and use it as a module.

    If all of the site was dynamic content, then i suppose authentication info could be embedded into each page. But not all pages are dynamic, so the information's gotta be stored somewhere - and that somewhere isn't server-side (think what happens if you're on a dial-up connection and you pull your plug, someone else gets your IP and without cookies, the server doesn't know that its a different person).

With Tivo the 'subscription' service is simply rental for the machine.

Tivo lose cash on every box they sell to get people hooked on the service.

    Tivo's lack of 30 second skip removes 60% of the reason to buy one. As does the closed nature of the box. It is not possible to move data from one Tivo device to another via wireless ethernet, it is not even possible to add extra drives to the box - not without inordinate hassle.

    Tivo will die, good riddance. They will be replaced by cheap commodity appliances from manufacturers that do not charge inflated subscription fees, or by better TV tuner card software for PCs.

    You missed the point. Thats fine, there is nothing wrong with that, but that is not the issue here. Web bugs are not attempt to gather statistics at a specific site, web bugs are attempts to track surfing across multiple unrelated sites. For example, say I visit a gay porn site, which have some doubleclick ads with hidden bugs in. Then off I go to Amazon.com to order a book about fly fishing, and unbeknownst to me, once again doubleclick has web bugs on Amazons site. So now a company (doubleclick) has a database linking the same user to those two completely unrelated activities. Now all doubleclick needs to do is establish some sort of affiliation with Amazon, and whammo, doubleclick suddenly knows my name, and has a database indicating that I have bought books on fly-fishing, like gay porn, browse slashdot, am anti-Microsoft, enjoy reading The Onion every Wednesday, whatever, they have a huge database on me. All without my consent or knowledge (which happens to be illegal in my country, but it would seem not in the US.) Sure you can say "don't use cookies" or "delete your cookies regulary", but what the fuck, thats not a solution, thats purely symptomatic treatment of the REAL problem, which is that these companies should be strictly prohibitied from doing this sort of thing in the first place. Either way, more than 80% of people are not even going to know how to delete their cookies or will just be too ignorant of the problem to care. Americans seem to love treating the symptoms of a problem but ignoring the actual problem itself.

    And you may not think doubleclick would be able to collect much info - but trust me on this - double is EVERYWHERE. It is virtually impossible to do casual web browsing for more than a few hours without getting doubleclick cookies. Try it. Delete all your cookies, browse for a while (casual browsing, e.g. some slashdot, maybe some cnn or other news sites, maybe some gaming sites etc), and see what cookies you have. Chances are extremely good you have doubleclick.net, bfast.com, hitbox.com, flycast.com, avenuea.com and a few of the other very common ones.
