The method includes creating at least one of a first content pre-key using a local storage key unique to the device as a key to encrypt the content ID of the content and a second content pre-key using the first content pre-key as a key to encrypt the first copy control state, creating a content encryption key using one of the first content pre-key as a key to encrypt the first copy control state and the second content pre-key as a key to encrypt the second copy control state, and encrypting the content using the content encryption key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Content encryption using at least one content pre-key","description":"In a method for encrypting content, the content is received in a device and at least a portion of the content is stored to thereby associate the content with one of a first copy control state and a se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462954","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
