Furthermore, authentication of a rights object defining the scope of access allowed for a digital property instance may be achieved through use of a signing key in the anchor point. The signing key may be used to assure no tampering has occurred with the rights object since acquisition of a digital property instance. A digital property owner may gain additional functionality and control through implementation of a play counter, rental duration limit, etc., using a signing key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rights object authentication in anchor point-based digital rights management","description":"Digital lights management (DRM) can be effectively implemented through use of an anchor point and binding records in a user domain.
