DESCRIPTION:
BRIEF SUMMARY
SUMMARY OF THE INVENTION
This invention permits to impede present easiness for industrial spying or else by means of document reproduction or remote-diffusion devices. It permits, by the coupling between, on the one hand, the creation of complementary graphic elements in the document and, in the other hand, the conception of adapted methods: sensitive documents, having a intrinsic value in order to facilitate the distinction between the original and its copy, payment of expenses relative to author's rights, reproduction of the electronic original detained by the original emitter, transaction controlled by the emitter of the original document, excerpt of this one.
To these purposes, the present invention centralizes the following functions: the document and, should the occasion arise, extracting the reproduction rules linked to the document, copy or carrying out an electronic transaction, according to the reproduction rules and the expressed request; if required by searching the electronic original.
Today, in the different characteristic elements of document making or reproduction, there are some risks linked to the confidentiality of the information contained in the document or in the use of the produced document: means of a copy machine within the company. The copy can be easily moved outside the company to its detriment and without any trace, since there is no disappearance of the original. facsimile systems and without any trace of this leak nevertheless very harmful to the company. means of the integration of more and more efficient technologies, to get copies very faithful to the original, making the differentiation between the copy and the original difficult without having recourse to a more and less extensive expertise. documents can cause, by means of some non-detectable alterings or falsifications, misappropriations of rights that they can generate (tax form, birth certificate, receipts, contracts, invoices, checks . . . ) whatever the sophistication brought to the elaboration of the original document. presently paid only by the diffusion of the original and not by the possible copies of these originals. can't be easily copied by their owner, due to their nature (binding, clipping . . . ) or to their deterioration (incomplete document, partial diffusion). produced document that may be highly confidential can be consulted willingly or unwillingly by third persons between the instant of its production and the instant when it is recovered by its owner.
To all these problems related to the safety of diffusion and use of the documents, not very efficient or too awkward conventional solutions that are presently applied are: key) of the strategic documents of the company or by a limited access to the reproduction means. This is often ineffective, due to a bad estimation of the strategic importance of some documents and to the difficult discipline rarely applied for this protection. media or technologies (metallic wire, magnetic ink or track, holograms . . . ) difficult to implement or costly. The complexity of these solutions limits their use and often only an expert can distinguish between true and false. be absolute only by a written confirmation request to the emitting authority. This process is heavy and can often be implemented only exceptionally and when there is already a doubt. prohibit such copies, but out of penal sanctions that are not easy to apply and that are not very dissuasive, nothing really impedes such infringements. make a manual request to the author of the document when this one can be identified and when he has means for answering to this request; as a consequence the present limits. terms of organization and maintenance and that can't prevent main structures from being provided with collective printers for more sophisticated works.
The method and devices for implementing this method permit to solve this problem for safety of production, diffusion and use of sensitive documents. Prior to the definition of the invention, it would be useful to define the different kinds of document
