When an organism
gives out a sensitive document, in addition to the display
elements previously defined that it inserts on the document,
it can stock the electronic version of this document on a dedicated
server. Below, we will also describe the applications of our solution that
don't need a dedicated server. In this report we describe
the most complete solution that can be offered in terms of
architecture.
When there is a reproduction request, the equipment of
reproduction or acquisition tests every page of the document
presented beforehand. It determines the sensitive characteristics
of this one by going through a search of the marking. When
it is a sensitive document, then rules are examined.
If constraints of reproduction are defined, then they are
applied.
If the issuer of the document foresaw it, the
copy owner can require a copy of the document certified
by the dedicated server of the issuer, or even ask him to
forward an electronic version of the document to his computing
system.
The issuer of the document can also manage the diffusion
of his document perfectly. Knowing its copy owners
at any times, he can easily send them an
update of this document or relative complementary
documents. He can check the use of the document, since
he is informed every time the document is used in order to get some rights.
He will thus be able to block all non-certified
operations based on the use of his document. Or even if the distributed
document makes initially reference to a situation that has evolved,
to inform of the changes any organizations that used the document
so that they can adjust their operations based on the initial information.
The access to the issuer's dedicated server is limited to the
electronic document already bound to the paper document
in possession of the recipient as well as to the associated
documents if the issuer allowed it. The access to the recipient's
computing system by the issuer is limited to the desired sending
and authorized by the recipient.
Next, we illustrate the implementation of this solution in different practical situations.
