The leaks of confidential documents, depending on their origin, leads to sensationalist or damaging public disclosures for companies victims of such leaks. In other cases, such information although not made public, ends up getting to competitors, or even worse, criminals.

The damages caused by leaks of documents are very visible, and almost always very serious. They can be financial, reputational or in competitiveness.


SHADOW is an automated tool that allows the traceability of documents by using techniques of digital watermarking. Shadow provides evidences in the event that confidential information leaks happen, helping to identify those responsible for the infringements.
