General information
- Short Summary
-
The SME has developed advanced audio steganography technology that embeds inaudible, tamper-proof data into live or recorded audio streams.
The watermark survives digital-to-analog conversions, MP3 compression, and detects unauthorized edits of the audio recording. Ideal for copyright enforcement, secure communications, and tracking the distribution path of the content, it is available as a SDK with API for integration.
The SME seeks research partners for EU projects and commercial agreements - Full Description
-
A Spanish SME specializing in audio security technologies has developed a cutting-edge steganography solution for embedding hidden information directly into audio signals. Unlike file-level watermarking, this technology merges data with the audio signal itself, ensuring inaudibility and robustness against common distortions.
Key features:
• Embeds 8–20+ bits of hidden data into audio streams or recordings
• Survives MP3 compression, resampling, analog conversions, and noisy channels
• Detects tampering (e.g., cut-and-paste attacks) to ensure content integrity
• Operates in real-time and post-processing modes
• Supports Windows and Linux platforms
Technical specifications:
• Minimum audio length: 2.4 seconds (recommended: 7.2 seconds)
• Processing speed: 100x faster than real-time
• Compatible with common audio formats (WAV, MP3)
• SDK includes C++ API for easy integration into embedded systems or software
Applications include:
• Copyright protection for audio/video content
• Hidden data transmission via radio/TV broadcasts
• User tracking in call centers or digital content distribution
• Tamper-proof verification of legal/contractual voice recordings
• Secure metadata embedding for IoT devices
The technology leverages psychoacoustic models to ensure watermarks remain imperceptible to human listeners while resisting extraction by unauthorized parties. Its robustness makes it suitable for forensic applications and high-security environments. - Advantages and Innovations
-
• Inaudible data embedding preserves original audio quality
• Tamper-evident design detects unauthorized modifications
• Robust to analog-digital conversions and lossy compression
• Real-time processing for live audio streams
• SDK enables integration into diverse platforms
• Customizable payload size for flexible use cases
• Compliance with forensic security standards
• Lightweight implementation for embedded systems - Stage of Development
