Watermarking

Watermarked ebook contains both visible and invisible information about the purchase. Based on the watermark, the original buyer information can be tracked if the ebook ends up for example at illegal file distribution services.

Watermarked ebooks are being delivered in their original format. This means that one can read watermarked ebooks with any software or device supporting the format. The content can be used in several devices without upper limit, as long as it's personal usage. Printing and copying to clipboard are also allowed for personal usage. However, please note that all non-personal use, such as copying or unauthorized distribution of watermarked titles, is still strictly prohibited. The watermark will get recorded also to copies made from the original ebook.
