AI Summary

This paper proposes RealSeal, a novel approach to media authentication that embeds a realism score into image metadata at the source. Instead of watermarking synthetic data, RealSeal analyzes multisensory inputs (visual, audio, thermal, motion) in real-time using machine learning to assess content authenticity and generate a robust realism score.

Abstract

The growing threat of deepfakes and manipulated media necessitates a radical rethinking of media authentication. Existing methods for watermarking synthetic data fall short, as they can be easily removed or altered, and current deepfake detection algorithms do not achieve perfect accuracy. Provenance techniques, which rely on metadata to verify content origin, fail to address the fundamental problem of staged or fake media. This paper introduces a groundbreaking paradigm shift in media authentication by advocating for the watermarking of real content at its source, as opposed to watermarking synthetic data. Our innovative approach employs multisensory inputs and machine learning to assess the realism of content in real-time and across different contexts. We propose embedding a robust realism score within the image metadata, fundamentally transforming how images are trusted and circulated. By combining established principles of human reasoning about reality, rooted in firmware and hardware security, with the sophisticated reasoning capabilities of contemporary machine learning systems, we develop a holistic approach that analyzes information from multiple perspectives. This ambitious, blue sky approach represents a significant leap forward in the field, pushing the boundaries of media authenticity and trust. By embracing cutting-edge advancements in technology and interdisciplinary research, we aim to establish a new standard for verifying the authenticity of digital media.

Key findings

The paper introduces a novel approach to media authentication focusing on source watermarking rather than detecting deepfakes after creation. The proposed method leverages multisensory data and secure hardware to improve robustness against manipulation, aiming to establish a new standard for verifying digital media authenticity. Limitations acknowledged include the possibility of staged scenes even with high realism scores and the fact that benign edits invalidate the score.

Approach

RealSeal captures multisensory data (visual, audio, thermal, and motion) using various sensors. A machine learning model processes this data to generate a realism score, which is then cryptographically signed and embedded in the image metadata. The entire process operates within a secure hardware/OS environment to prevent tampering.
