Sood Tattoo

Sood has developed a patented watermarking technology for textual documents regarding the most sensitive documents (confidential ones) of a company. It does not interfere with the aesthetics of the document.


This tattoo can integrate on each elementary portion of the document some referencing elements related to the identity of the document and to its owner.


The watermarking of a document is very fast and can be done on a PDF document without adding to the weight, and is also valid for printed documents. He survives a printing process if the document is electronic and scanning if it's a paper.


It can be detected and analysed from a photo taken by a smartphone no matter whether the document is pictured from paper or displayed on a screen.


This tattoo is implemented in our security solutions (described elsewhere).
