Let's say, someone wants to ocr, for example a light-novel series which had never had a digital release, with commercial(bought) software(like Abbyy for example), how safe would it be to avoid any kind of tracing(we assume vpn is default).
For example, would the ocr leave some kind of hidden watermark which could be traced back to the point of purchase(of the ocr). Or could the books themselves contain some kind of mark(I think unlikely, simply too much trouble for physical book runs).
Would that certain someone be better off using a free ocr despite all the extra work(formatting etc)?
