The deal also means Sony BMG must abandon use of the XCP and MediaMax programs and provide tools that help people clean the software from their PCs.
It must also fix any new vulnerabilities the programs are found to create or which are created by any anti-piracy system it adopts in the future.
Sony BMG must also change the way that it tries to protect music on discs and in the future must clearly label and test its anti-piracy systems. The methods it wants to adopt must also be independently audited.
