Problem
Content owners face significant challenges in protecting digital media files from unauthorized distribution and piracy, especially after distribution to reviewers or for educational purposes. Traditional Digital Rights Management (DRM) systems can be cumbersome and ineffective, failing to prevent leaks and identify the source of infringement. Detecting and tracing the source of leaked content across various online channels, including the dark web, is difficult and time-consuming.
Solution
Custos provides a content protection solution that uses imperceptible watermarking and blockchain technology to safeguard digital media and trace unauthorized sharing. The technology embeds unique, encrypted digital bounties within each file, enabling rapid detection of piracy. When an unauthorized copy is shared and the bounty is claimed, the content owner receives an immediate alert, revealing the source of the leak. This approach leverages a distributed network of bounty hunters, incentivizing them to identify and report pirated content, even in hard-to-reach places like the dark web and private networks.
Target Audience
The primary target audience includes movie studios, book publishers, educational institutions, and enterprises that need to protect their digital content from piracy and unauthorized distribution.
