Digital rights management (DRM) consists of compliance and robustness rules. Which of the following features does the robustness rule have? Each correct answer represents a complete solution. Choose three.
A.
It specifies the various levels of robustness that are needed for asset security.
B.
It specifies minimum techniques for asset security.
C.
It specifies the behaviors of the DRM implementation and applications accessing the implementation.
D.
It contains assets, such as device key, content key, algorithm, and profiling data.

The DRM (digital rights management) technology includes the following rules: 1.Compliance rule: This rule specifies the behaviors of the DRM implementation, and applications that are accessing the implementation. The compliance rule specifies the following elements: Definition of specific license rights Device requirements Revocation of license path or penalties when the implementation is not robust enough or noncompliant 2.Robustness rule: This rule has the following features: It specifies the various levels of robustness that are needed for asset security. It contains assets, such as device key, content key, algorithm, and profiling data. It specifies minimum techniques for asset security.
A. It specifies the various levels of robustness that are needed for asset security.
B. It specifies minimum techniques for asset security.
C. It specifies the behaviors of the DRM implementation and applications accessing the implementation.
The robustness rule in DRM is concerned with specifying different levels of security required by digital assets, minimum techniques necessary to secure such assets, and defining expected behavior from both DRM implementation and applications interacting with it. The fourth option, D., refers to specific components or resources utilized in implementing DRM rather than a feature explicitly present in its robustness rule.
Robustness rules and requirements for DRM are defined in several industry standards, including the Digital Rights Management (DRM) specification of MPEG-4 Part 1 (ISO/IEC 14496-1), Open Mobile Alliance's (OMA) DRM specification, and Microsoft’s PlayReady technology. These standards outline the various levels of protection that content creators can choose to apply to their digital assets by dictating specific technical requirements that must be met by implementing systems if they want to achieve robustness certifications or compliance.
