Open a foreign bank account in a tax haven like Switzerland or the Cayman Islands. Banks in these countries are not required by law to hand over information about your account to anyone without your consent. If you open what's called a “numbered account” in a private Swiss bank like Union Bank of Switzerland or Credit Suisse Group, a number or code name will be associated with the account, rather than your name. To open a numbered account, you will most likely need to travel to Switzerland to do it, though if this is impossible, there are firms that help people set up off-shore bank accounts that can help you. You will most likely need to make an initial deposit of at least $100,000 to open the account, which will cost roughly $300 a year to maintain.

The notion of intellectual property—the idea that artists’ works belong to them—dates at least to medieval Europe, though history records examples of the concept as early as ancient Greece. It had taken hold sufficiently during the Renaissance for Michelangelo to take umbrage when his work was misattributed. It was reported that when he discovered that another artist was receiving credit for sculpting the famous Pietà (now in St. Peter’s Basilica in Rome), Michelangelo returned with his chisel and added his signature across the centre of the sculpture, on the prominent sash across Mary’s upper body (in Italian): “Michelangelo Buonarroti, Florentine, made this.”
