Security practices for paper documents are required in order to
authenticate the document source, the integrity of the information,
and to distinguish copies from originals. We are presently exploring
various approaches to achieve this. The security practices for paper
are highly important in a variety of applications. An example for

Being able to deal with documents that have
pictures and different scripts.
Ensuring tamper-proof security of these documents,
etc.
