Electronic Document Securisation based on Document Structure

Securing electronic documents is an important task. It secures the identity of a document. In this sense, methods (mainly cryptographic methods) have been put in place to guarantee the secrecy of the meaning of messages as well as the signing of documents from certificates. The digital document is only defined by its textual content. With the rise of OCRs, the alteration and fraudulent use of documents has increased. In this work we propose an algorithm based on the use of a code book to secure the identity of the document. The codebook stores information that uniquely identifies the document. The codebook is used to make a correspondence table between the elements that we consider important to take into account in the modeling of a document and the different values that are associated with these elements. The results of our algorithm show that it is quite efficient.
