A unique signature, comprising a plurality of data bits, is associated with a user and divided into groups. For each group, a different sine wave is created for each bit in the group. The frequencies of the sine waves correspond to the types of bits, and the amplitudes of the sine waves indicate the values of the bits. Group signals are overdubbed on the infrasound range of the audio track of the video file. The unique signature is decoded from the video file by analyzing the frequencies and amplitudes of sine waves in the infrasound range of the audio track."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System, method, and computer program for encoding and decoding a unique signature in a video file","description":"The present disclosure describes a system, method, and computer program for encoding and decoding a unique signature for a user in a video file, wherein the video file was created using a video format","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813725","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.
