THE ROBUST FORENSIC AUDIO WATERMARKING

CONTENTARMOR Audio Watermarking is a technology intended to deter actors along the content value chain from leaking content. To do so, an inaudible forensic watermark is embedded within the content to uniquely identify the device or the recipient whom it has been delivered to. By watermarking the uncompressed audio content, CONTENTARMOR’s audio watermarking algorithm achieves high robustness while keeping perfect audio quality. High embedding speed through performance optimized algorithms allows easy workflow integration.

How Does It Work ?

The Embedder
  • Analyzes the audio signal using a sophisticated psychoacoustical model
  • Converts the unique identifier (ID) into a bit stream Customer Key Pirated Copies
  • Adapts the signal to include an em- bedded bit stream using the customer specific key so that the audio quality remains the same as before.
Deployment Scenarios
