When an organism sends out a document, it also grants access to miscellaneous rights to the recipient. An earnings statement leads to get funds or an apartment. An invoice leads to enrich the accounting or the concerned person's imposition or even to get refunds from a third party. An order form allows banking facilities in a company. A cashier's cheque meets with a transfer of liquid assets. This list is far from being exhaustive and every one is able to think about any keys that come with the documents that one gives out regularly. The result of this thought will eventually confirm the vulnerability of a company if the documents that it delivers are not controlled.

We talk about real risks, as few are the companies that don't undergo such diversions. It is an acknowledged fact that the technologies' evolution will make it easier for any individual to falsify a document and to divert its use of it. The solution cannot depend upon sophistication of the documents' manufacture, recent examples of production of counterfeit money by hardware office automation accessible to all show well the limitations of such approach.
Our patent lies in a constant interaction between the document's owner or the owner of one of his copies and the document's issuer. Any change of the document thereby, whatever its sophistication is, remains without effect at the time of the right's assignment linked to this document.

The following diagram shows the security of the patent within the scope of the emission of a cashier's cheque. This description can be applied easily to other types of documents.
In the quoted example, the company we call "Insurer" sends a check-letter to Mr. Clark for an amount of $ 125.45. This keeps a tally to some repayment due to Mr. Clark. Mr. Clark has his mail stolen. In fact, Mr. Clark doesn't know that the repayment was sent to him, he is therefore not able to report it.

The one who stole the mail can easily use this cashier's cheque by falsifying it or by restructuring a new document using the original's main references with a new recipient and a new amount.
In the classic case, the corresponding check will be paid to the false recipient for the new amount. The issuer will have then unduly paid $ 12,500.60 to Mr. Brown (in our example) but will have to repay the amount due to Mr. Clark after having undergone his complaints too. Meanwhile the amount unduly paid to Mr. Brown will have had the time to disappear somewhere amid various banking cash flows. Now if one considers the case where the initial letter is being issued by using our process, at the time of the clearing, the original, or at least a communication of the main elements of the document is required. A quick comparison between those allows to stop the operation and to take the necessary safety measures either to the level of the non-payment of the $ 12,500 or to intercept the forger.
