In an era of ubiquitous digital surveillance and data harvesting, the intersection of multimedia consumption and personal privacy has become a critical focal point. As users stream and share video content, they often unknowingly transmit sensitive metadata. This paper examines the application of —an extension of ISO/IEC 27001—to the lifecycle of MP4 files to ensure Privacy Information Management Systems (PIMS) are maintained throughout the media supply chain. 2. Understanding the Components ISO/IEC 27701: The Privacy Framework
: Encrypting only the metadata boxes that contain PII while leaving the video/audio streams accessible for playback. C. Transparency and Consent
: Capable of storing extensive "atoms" or boxes containing GPS data, timestamps, user tags, and device information.
