Shadow is a technology that enables traceability of documents by means of imperceptible watermarking techniques applied to text documents
Shadow renders each document copy unique, offering each document holder a “personal” copy (mark identifying the owner) by means of small non-intrusive modifications that produce a marked document seemingly identical to the original one.
The hidden information, resistant to numerous distortions such as those produced by printing, photocopying and scanning, allows the system to identify, by extracting the mark, the owner of the document, which provides where leakages have been produced and who is accountable for it, whether it is accidental or on purpose.
