<p>In the document (D) archiving system (F), documents present themselves in the form of data (E), provided with a seal (S) attached by the sender of the document. Each document with the exception of the first document (D1) includes a safeguard seal (SS2,SSn) calculated by an algorithm (C) from the seal (S2,Sn) of this document and from the safeguard seal (SS1,SSn-1) of the preceding document (D1,Dn-1). The safeguard seal (SS1) of the first document (D1) of the series is calculated from its sealing seal (S1) and from a initial random key (A) comprising the security signature of the data (F). Inserted in the document series are a number of artificial documents (Dr) emitted by the archiving system.</p> |
