Novel algorithms for data processing in audiovisual surveillance systems were developed allowing for a better personal data protection. The solution merging the image and audio encryption for privacy-sensitive data protection employing audio stream is described. The main objectives of this research study including motivation and the state of the art are presented with a comprehensive explanation of audio stream relation to the surveillance. The invertible encryption methodology for privacy preserving using audio container is applied. The experiments are described and obtained results are reported including prospects for future improvements.
