7 лет назадBitcoin bounties against pirates
The South African anti-piracy firm Custos has developed a new form of anti-copyright infringement digital watermark which contains a small amount in Bitcoin:
What makes Custos’ approach unique, are the small Bitcoin deposits hidden in each copy of an ebook. As long as an ebook is still within the intended recipient’s control, the deposit remains intact. However, the Bitcoin can be claimed as a bounty from anywhere in the world if the ebook happens to be shared within a piracy network. Once the bounty is claimed, the transaction is visible on the Bitcoin network within seconds, and the publisher is notified that an infringed copy has been found. Since each embedded Bitcoin bounty is unique, the identity of the infringing customer (the initial file sharer) is also revealed. (Blog)
