Anti-forgery
Today, the best forgeries of passports in its entirety are still produced by redrawing the original passport artwork, often conducted by hand by skilled artwork specialists. The resulting work is often impossible to authenticate without careful study by experienced personnel and the use of specialized equipment.

However, because Trustcopy's watermarks are embedded with covert and encrypted authenticity information, which is not revealed to the naked eye, the technique of redrawing the certificates so preferred by forgers will not reproduce the embedded covert information.

So a seemingly visually authentic document forged by redrawing can be easily authenticated when by establishing presence of the authenticity information in the watermark, simply by using an optical key.

So the technique of redrawing cannot be used to reproduce Trustcopy protected passports, forcing the forgeries to be made using scanning where a new photo film or scanning is used to capture the original watermark. However there is always degradation of image quality using this technique. And this adds to another security feature of Trustcopy's watermark, reproduced Trustcopy watermarks are always different, making them copy evident.

Modifications of details on genuine and forged documents
Trustcopy incorporates encrypted dynamic watermarks that are digitally printed with the details of the passport, like name of the holder, date of birth, expiry date, picture of the holder and other details into each passport. As the perpetrators can only alter the visible details, it is easy for front-line inspections to be conducted on the passports by comparing the visible details against those found in the encrypted covert watermarks.

Unauthorised creation of Passports using blank genuine stationary

A Trustcopy protected passport incorporates encrypted dynamic watermarks that are digitally printed with the details of the passport, like name of the holder, date of birth, expiry date, picture of the holder and other details into each passport.

Only passport printed using Trustcopy's secure printing module can generate such watermarks, so this adds an extra level of security to prevent unauthorised use or abuse of genuine stationary.

Trustcopy provides both software and hardware printing modules for its watermarks, can be incorporated into the system of an existing passport printing system and has options to secure printing by bio-metric access such as fingerprint matching.
