dynamic watermarking of ebook

-

hi

i´m start selling e-books (pdf) webshop, , want have dynamic watermark in pdf, containing buyer´s name, date, ordernumber etc. "livecycle rights management es" part of acrobat pro or separate piece of software? can aap automatically draw out wanted information order confirmation , insert in pdf downloadable buyer?

adobe acrobat cannot installed , operated on webserver. livecycle es3 separate product line enterprise users. can add selection of modules es3 server installation manipulate , protect pdf files, integrating want require extension scripting orders database can talk generator utility. it's possible not job novice user, , lc es3 expensive.

 

on commercial level you're better off writing yourself, using php etc. - there several open-source libraries manipulate pdf files including things adding watermarks, , simpler code connection ordering system way. major commercial advantage of lc digital rights management module, way make file secure against distribution - unless ebooks have extremely high value or contain classified information costs of using drm outweigh possible losses illegal copying.
