## About the product

Custos is a content protection platform for rights holders and organisations that distribute digital media and need to detect piracy and leaks quickly and precisely.

Key capabilities include:

- **Blockchain-based forensic watermarking** that embeds imperceptible, recipient-specific identifiers into each copy of video, ebooks (including PDFs), and documents, enabling leak tracing when an unauthorised copy appears.
- **Cryptocurrency bounty detection** that embeds small Bitcoin (or other cryptocurrency) bounties into protected files, so anyone who finds a leaked copy can claim the bounty, which triggers an alert and helps identify the original recipient copy.
- **Video Security and DRM integration** delivered as an **API integration** for existing VOD workflows, designed to support rapid tracing of pirated video.
- **Education and enterprise protection options**, including an **EdTech plugin for Moodle** to protect course materials (PDFs, ebooks, videos), and **Enterprise Document Security** built to integrate with **Enterprise Information Management (EIM)** systems for traceable document sharing.

Available via **Web (SaaS)** and **API integrations**.

Target users include film producers, VOD platforms, publishers, edtech providers, and enterprises distributing sensitive digital content.

Based in **South Africa** (founded in 2014), the company is notable for its **patented** approach to “distributed protection” that pairs forensic watermarking with blockchain-based bounties, and for international press coverage of its Bitcoin-bounty model for anti-piracy and leak detection.
