When using electronic documents it is impossible to sign them with the help of graphical symbols. Digital symbols can be falsified and copied many times. Thus electronic digital signature (EDS) is used. EDS is the full electronic analogue of the common paper signature, but it is realized with mathematical document transformations. The mathematical nature of the EDS guarantee that you signature can not be falsified by any outliner. The information is also protected unauthorized access. This new technology is very important when managing your document workflow. The EDS is used in varied spheres. The electronic signature is legal, as the result you can use it in relations with your business partners and lawful bodies when changing documentations and different reports. Electronic document workflow allows corresponding with partners and also entering into agreements by electronic mail.

As you may know PDF format is a standard for many document types: you do not need choosing certain fonts to view a document and PDF files look the way it was planned by an author. PDF is an independent format: it looks the same regardless application software, hardware and operating systems. Taking this into account most of the electronic document interchange between different bodies is made using PDF.

Documents in PDF format also need to be protected with electronic signatures in order to be legal. There are several programs that allow doing the protection. Among such programs you can find Altsoft Xml2PDF that converts Xml-based documents to PDF and other formats such as PS, XPS, raster formats. Moreover, when converting documents to PDF you can protect them with EDS, add watermarks and make other manipulations. Almost the same functionality has the Rainbow PDF Digital signature. It has different options and allows setting digital signatures versus the level of security. Alternatively, you can try Bytescout.PDF libraries to sign a document.

Securing documents with digital signatures allows saving document transfer costs, delivering information in time, reducing subsidiary costs such as printing, scanning, posting, etc.
