Technology can offer options that apply any combination of content protection, hardware and software tamper resistance, or cryptographic keys to achieve content-ownership protection. The authors describe two methods for protecting content by creating a legitimate distribution channel. One method broadcasts encrypted data to a selected set of users and uses a tracing algorithm to uncover the compromised key's owner. The other method updates user keys to resecure a compromised network.
