Computer IDing

The topic recently came up between a friend and myself, about how someone could identify a computer if it were ever stolen.

For our examples, we'll be using a simple laptop, and ignore all hardware distinction.

1.) Computer naming, files and preferences
Solution: Re-format the computer, backing up files onto a second disc.
2.) Computer tracking software
Solution: For those pieces of software designed for Windows, re-formatting won't work, as the information lies in the FAT Sectors. Ironically, if someone were to change the partitions around, re-format and switch to an NTFS partition...
Note: Switching to an NTFS partition will still leave an automatic FAT32 partition on your computer, of about 20 some Megs, where the boot files are kept. (Atleast on my XP Box) That IS assuming they don't install Linux or FreeBSD over Windoze.
3.) BIOS protected notes
Solution: Replace the BIOS...if the person can manage to do that in the first place.

Of these three solutions, only number three truly seems reasonable for maintaining a way to identify your computer. Of course, number two would also work, but its not fool-proof.

Does anyone know of any way to completely ensure that their computer can be found and identified? Or atleast any good ways not mentioned here?

Thanks!

I would suggest that, for the largest part, people who steal computers are those who are unsophisticated in their use and would be unaware of the deeper things that can be done to id the computer later. Formatting etc. would be way above them as would replacing the BIOS.

I would also suggest that in many cases the person who they sell the computer to, (at a handsome discount I might add....<s>), would probably be of similar sophistication.

Now if we are talking about an organized ring of people who do this for a living I retract all the above....<s>

A relative of mine is chief of police a a college in the northeast. He purchases specially designed steel plates that are chemically sealed to students' laptops. It has a registration number on it and the police dept. keep a database of all the numbers; linking owners, serial nos., etc.

The cool part: If the plate is ever removed, it leaves behind a bright yellow chemical "stain" on the surface of the computer that says, "This computer is stolen property. Please notify XX."

Although it doesn't help in finding the computer all that much, it can certainly help to identify it once found.

If I can find a link, I'll put it up.

I remember seeing something that sounded an alarm if a laptop was taken a certain distance from a device-this would be useful in airports and such.

In our experience the intelligence of most thieves is not impressive. It is usually a quick grab of one or two devices and immediately to the pawn shop. How about some kind of label inside the case. I know it would be a pain to to install but I don't think the normal thief would bother taking the device apart to remove something like that.

Talking about those BIOS tweaks, company of my friend is using method to secure their data (and the computers maybe) by recoding Flash-BIOS. So as I remember, they encrypted the data on HD or only the first sectors, and by the password protection user could use the data and computer.

Replacing BIOS would let the thief to bypass password protection but the HD would be unusable (until reformat)..
