Layered assurance
DCP Cine Player security
Security is treated as a chain: authenticated users, recipient-bound keys, trusted time, validated content, protected output, signed software and documented operations.
Identity and access
Four operational roles, configurable sessions, content certificates and permissions that separate observation, playback, management and administration.
KDM security
Certificate identity, composition/key matching and validity windows gate encrypted playback; rejected material is reported rather than silently accepted.
Content integrity
DCP asset checks and EAR‑Tech authenticated chunks detect missing, mismatched or modified media before or during use.
Output protection
HDCP preflight and supported display identity checks protect applicable encrypted playback paths; hardware qualification remains deployment-specific.
Release trust
Release manifests and packages are checked against pinned signing keys before controlled installation.
Operational evidence
Logs, system details, status views and documented commissioning provide evidence for support and local security procedures.
MPA/TPN positioning
The MPA Content Security Best Practices, maintained by TPN, are a broad benchmark for security preparedness across organisations, facilities, applications and workflows. D‑Cine Player and EAR‑Tech provide technical controls that can contribute to meeting applicable practices, including protection of stored content. A TPN assessor and the content owner determine conformance for a defined scope; installing this product does not grant certification, assessment status or approval.
