Dear Revolutionaries Is there any way to access something like a unique ID number for the computer currently running the rev app?
It is my understanding that Intel starting giving all CPUs a unique IDs a few years back, probably to help MS combat software piracy. I don't whether other chip makers do the same (AMD for example). More generally, my question is: Is there any way of obtaining or generating some kind of unique ID for an individual computer, for licensing purposes. I have read a lot of discussion in the rr archives about using crypto keys and hidden license files and so on. It seems like getting the CPU ID (perhaps through the Win API) would be like the best way to do it. I had another idea for this - if you write files to a disk, the exact addresses and distribution of file fragments will arguably be unique on anything except a newly formatted disk. To get around even this limitation, what you could do is use a random number sequence to generate a whole bunch of random files of differing lengths and to delete a random subset of them and expand a random subset of the ones that remain by a random number of bytes. The remaining pattern of files on the hard drive would then act as a kind of digital signature that you make a digest of using their hardware addresses on the disk (sector and block numbers) and their random contents. Even if somebody copied all these files to another computer, their distribution on the new disk would not be the same and only by imaging the entire original hard drive and outputting the result onto another drive, could you reproduce this (unless you had access to your hard drive at the hardware level and could write bit sequences to specific sectors and blocks). You might even be able to make this tougher to do by incorporating the index of bad blocks for the original drive, into the digest. Could such a dsik drive fingerprint scheme be feasible (or maybe its already been done)? Replies to my this and to my original question would be greatly appreciated.
