How it works

Screener Copy is an online video hosting, watermarking, and distribution platform, built by Custos Media Technologies

Custos provides content protection services for owners and distributors of digital media.

Essentially, Screener Copy is Custos’ Software-as-a-service (SaaS) product, designed for independent film producers and small-to-medium-scale movie distributors.

A Screener Copy user can simply upload content, get it imperceptibly watermarked, and nominate a list of recipients to receive a link to view a unique copy of the video. Custos protection is added to each copy; a process made up of two parts:

1. Forensic watermarking of digital content

  1. A media file is uploaded to the Custos service (e.g. Screener Copy).
  2. The original (unwatermarked) content is securely stored, and never redistributed.
  3. A client nominates the persons, groups, or organizations which should receive copies.
  4. Custos embeds a unique Bitcoin bounty into each copy, making them easily identifiable and traceable.
  5. When a recipient downloads or streams the media on the Screener Copy platform, Custos serves them the uniquely (and invisibly) watermarked copy.

2. Copyright infringement detection

  1. A recipient leaks a copy of their digital media file.
  2. A network of cryptocurrency ‘bounty hunters’ across the globe scans media files found on piracy sites, or even the dark web, for hidden Bitcoin bounties.
  3. Once found, the bounty hunter anonymously claims our embedded cyptocurrency as a reward.
  4. The moment a bounty is claimed, the media owner is notified that an infringement has been detected.
  5. From the unique bounty claimed, Custos knows which copy of the media file has leaked, allowing the media owner to identify the original infringer.
