For each sector in the PBA image, the method also includes computing an error tolerant cyclic redundancy check (ETCRC) value and searching for the ETCRC value in the LBA search tree. If the ETCRC value is found, also included is comparing the cyclic redundancy check (CRC) of the LBA and PBA sectors, and outputting to an output file the PBA sector as hidden data if either the ETCRC value is not found in the LBA search tree or the CRC comparison fails."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hidden data identification in solid state drive forensics","description":"A method of isolating hidden data in a solid state memory system is disclosed including obtaining a logical block address (LBA) image from the memory system, obtaining a physical block address (PBA) i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778975","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.
