Security Basics: RE: Electronic signatures and watermarking?

["Adrian Floarea" <adrian.floarea () uti ro>]

 In this moment in time, the only valid method for business documents are
the real handwritten. You realize that: if you paste something on an
ordinary paper, how can you check the currency of this, or how can you
prevent the multiplication of this signature? What you want it's possible
but only on special paper (for money e.g.). Of course, you can use a pasted
handwritten on ordinary paper but you will have big problems to prove the
identity of this.
