Patent for Prevention of Electronic Content Capture Using Embedded Key Server Module

Strategic Insights -

A patent for a system and method for preventing electronic content capture using an embedded key server module has been granted to Lucy Mort and Nikolas Sean Ryan. The patent, filed on September 14, 2023, and published online on September 30, 2025, provides a method for secure media content playback on user devices. The system involves generating a key pair, storing the private key, and encrypting the media content using a media encryption key. The user device then retrieves the private key, decrypts the media encryption key, and decrypts the media content segments using a content key context.

Key Takeaways:

  • The patent describes a method for preventing electronic content capture using an embedded key server module, which secures media content playback on user devices.
  • The system generates a key pair, stores the private key, and encrypts the media content using a media encryption key.
  • The user device retrieves the private key, decrypts the media encryption key, and decrypts the media content segments using a content key context.
  • The patent provides 15 claims, including the non-transitory computer readable storage medium storing computer instructions for prevention of electronic content capture.
  • The system uses an advanced encryption standard (AES) algorithm to encrypt the media content segments.
  • The patent obviates the need for user devices to communicate with a remote key server to obtain the content key context.
