Abstract: D-Cinema content is extremely valuable – it is high quality, available in digital form and released in the earliest window. To thwart theft and unauthorized manipulation, a combination of proactive cryptographic and physical security, supplemented by authenticated log reporting and forensic marking, is necessary. Specifically, D-Cinema content needs to remain encrypted throughout the theatrical distribution chain, from the time it is encoded during content preparation to the time it is projected on a theatre screen. Only trusted devices – deployed in secure environments or implementing physical protection – should be given access to the cryptographic keys necessary to encrypt and decrypt content. Trusted devices may also be required to maintain a log record of security-related events and, in the case of devices performing content decryption, add a forensic mark to the decrypted content.
