DECODING/DECRYPTING BASED ON SECURITY SCORE

摘要

A security system provides a security score (125) that corresponds to a likelihood that received content material (101) is authorized to be rendered, and controls (250) the rendering of the material based on the security score (125). The security score (125) can be compared (240) to a security criteria (151) that is associated with the material being rendered, so that different material impose different constraints. The security score (125) may also control (320) a level of quality/fidelity of the rendering of the material, so that, for example, a high-fidelity copy of the material is only provided when a high degree of confidence is established that providing a copy is authorized.
