I divieti nell'utilizzo di particolari tecniche di sicurezza.

When the legality of the security tecniques are analyzed,in particular the restrinctions in using them,it would be useful to state what it is intended with "restrinctions".Criptography suffers from many restrinctions in several countries in the world,more than watermarking,which is still not so much used as security tecnique.For sure,people's privacy is a fundamental right which must be protected,but the fact that it is nearly impossible to control cyphrate communications-thanks also to the perfection of strong alghorythm-produced a certain number of norms which are intended to limit application,sell and exportation of crypto products and related software.Here,products are intended as hardware designed ad hoc to execute cryptography functions (for instance,a scrambler for telecommunications).
