Cosa sono i DRM, in realt\u00e0? Servono davvero solo e principalmente a limitare i modi di utilizzo di una risorsa digitale? Ecco come questi vengono spiegati, in maniera semplice e chiara, da Leonardo Chiariglione<\/a>:<\/p>\n

\u00a0So, let\u2019s first clear this one by stating the obvious: \u201cDRM is a means to manage rights with digital technologies\u201d. The definition is a tautology but when there is confusion the best is to start from the obvious. If I create a file and, before sending it, I digitally sign it, I am using a form of DRM because I digitally manage<\/em> my right make sure that the recipients of my file are informed if somebody has tampered with it. Ditto if I send an email with PGP. <\/font><\/p>\n

It is apparently a different story if I release an MP3 file of a song composed and played by me with a Creative Commons (CC) licence. In this case I am managing my author’s and performer’s rights attaching (or making reference to) a human readable licence. If, however, I express the CC licence in a computer-readable form, I digitally manage<\/em> my rights, i.e. I apply DRM.<\/font><\/p>\n

There are, however, people who add to the DRM (management) technologies described above other (protection) technologies in order to physically force people to comply with their expressed rights. It is an abuse of words to call these technologies DRM (even the most oppressive of managers do not make recourse to physical forcing), but I do not object as long as the original \u201cM as in management\u201d meaning is not forfeited.<\/font><\/p>\n
