My publisher is reprinting _Digital Copyright Protection_, a book that describes how to use encryption and steganography to control digital data. I get to fix any problems that are out there. To encourage people who may have spotted errors, I'm offering a bounty of $20 to the first person who reports an error subject to the following limitations: * The errors must be technical. I appreciate anyone who wants to correct my grammar, but I think that these types of errors are too hard to pin down. We could spend more time arguing than solving them. * I reserve the right to aggregate errors and determine the right way to split them up. This isn't a loophole, it's just a way to prevent someone from noting a pattern and asking to be paid for each separate occurance. For instance, imagine that someone notes that I forgot to put a page number on a blank page at the front of the book. Is every page number after that wrong? I promise I won't use this as a loophole. * I reserve the right to make arbitrary judgements about the "first" person to submit a claim. This is to prevent a club of people from finding an error and reporting it in synchrony. I may choose to pay each person the $20 reward, choose one I feel is most deserving, or even split the reward n ways. It's up to me. I'll probably choose the first one unless there are extenuating circumstances. Thanks to everyone who takes part in this project. Let me know if you have any questions. In the past, I've found that few people reported the errors and I'm hoping that $20 will be enough of an inducement. Perhaps there are no errors there? This is the best way to prove a negative. Thanks again, Peter Wayner
