The trusted party provides a decryption key to the output device but only after being satisfied that the policy has been met. The decryption key is generated in dependence on the encryption key string and private data of the trusted party. The output device uses the decryption key in decrypting the data to be output. Embodiments are provided that involve multiple policies and trusted parties."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data output method, system and apparatus","description":"Data to be output to a removable storage medium is encrypted for sending to an output device by an encryption process based on encryption parameters comprising public data of a trusted party and an en","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8510789","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.
