Medianonymizer

Medianonymizer provides a secure solution for removing sensitive data from a variety of file types, including documents, images, audio, and video. It addresses the need for auditable anonymization by combining AI detection with verifiable code to ensure that sensitive information is irreversibly removed and results are reliable and reproducible. The tool is designed to handle multiple formats such as PDF, DOCX, TXT, JPG, PNG, MP3, WAV, and MP4, making it adaptable for different data anonymization needs.

The anonymization process involves AI algorithms that locate sensitive data—such as faces, license plates, personal data, and voices—within files. Once detected, verifiable code is used to remove or redact this information: faces in videos are blurred using geometric tracking and ffmpeg remux, while sensitive audio is beeped out or silenced. For images, the tool removes faces, visible text or personally identifiable information, and EXIF/GPS metadata through methods like solid box redaction, strong pixelation, and metadata stripping. In audio files, spoken sensitive information is replaced with beeps or muted based on character-to-time mapping.

Medianonymizer is delivered as an online service, allowing users to upload files securely with encrypted transfer. The original files self-delete after processing, and the service does not retain data or use uploaded files for AI training. No account is required to use the tool, and users pay per job, aligning with GDPR requirements for data privacy and security. The platform emphasizes that its anonymization process is irreversible and auditable, ensuring nothing can be recovered from processed files.

This tool is suitable for individuals or organizations seeking a straightforward, secure way to anonymize sensitive information in various digital formats without requiring persistent user accounts or long-term data storage.
