How do Countermarks Work on Documents?

Countermark for Documents lets you annotate, validate or protect all types of documentation.

A web interface is used to upload the data you want a User to see on their phone when they read a Countermark.  This can be an Image, a URL or a PDF file:



In its basic form, all Countermark Users can read the Countermark data to validate documentation and detect forgeries.

You can, however, also remove (‘Cut’) sensitive data from a document and replace that data with a Countermark code (‘Paste’). The original data is held in a secure database and is only made available to Countermark Users on a ‘need to know’ basis.

The Issuer can then specify the read limits possible. These are independent of each other and include:

  • Public / Private / Registered.
  • Global / Geo-Locked.
  • Time-Locked.


The format of the Countermark can be selected to include:

  • Font Type – Latin, Cyrillic, Katakana or Chinese.
  • Top Row Text – 1st 4 characters of the Top Row can be selected (as long as not already registered to another Issuer).
  • Black dots on white background – best for paper.
  • White dots on a black background – best for computer screens.
  • The size of the Countermark (either standard or matched to the image uploaded (Image option only)).
