Title: A to Z copyright trick
Post by: Malcolm Bull on Sunday 15 October 17 15:16 BST (UK)

I know that the publishers of the A to Z maps add fictitious streets to their maps, in order to dissuade/detect people illegally copying their work.  Can anyone remind me of the name given to this little "trick"?

Also known as a "tell".

Used in sensitive documents that get circulated to a restricted list of people .... each copy will be slightly different - usually an extra space between words, or a misplaced comma.  Then if the document turns up somewhere it shouldn't it is easy to work out who leaked it.
