Secure Enclave Media Protection via GPU Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As wireless streaming of media content increases, content providers face challenges in securely distributing media while preventing unauthorized redistribution and piracy, as existing technologies fail to effectively protect media content from unauthorized access and corruption.
Innovation Solution
Implementing a secure enclave within user devices, which is a hardware-isolated environment directly coupled with a GPU, to process and display media content, and encoding media content with a unique watermark to trace unauthorized versions, ensuring secure distribution and protection from external software and hardware threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media content is distributed wirelessly to multiple users, then accessibility and convenience are improved, but security and risk of unauthorized redistribution deteriorate
Solution Approach 1:
The system segments media content into encrypted portions distributed across multiple servers, with each server holding only a fragment. Users receive segmented content that requires reconstruction, but unauthorized copying of individual segments remains useless without all parts. This segmentation approach enables widespread distribution while maintaining security through distributed encryption keys and fragmented storage.
Solution Approach 2:
The patent introduces digital watermarks as an intermediary mechanism embedded within media content. These watermarks serve as traceable identifiers that do not interfere with content playback but enable tracking of unauthorized distributions. The watermark acts as a mediator between content delivery and security monitoring, allowing convenient distribution while providing post-distribution security verification.
2Reliability
If traditional encryption methods are used to protect media content, then security is improved, but vulnerability to hacking and decryption deteriorates
Solution Approach 1:
The system divides encrypted media content into multiple segments distributed across different servers, each possessing only a portion of the decryption capability. This segmentation ensures that even if one server is compromised, the complete content remains protected. The encryption key itself is segmented and distributed, making unauthorized decryption extremely difficult without accessing all server segments simultaneously.
Solution Approach 2:
The patent implements preliminary embedding of unique digital watermarks into media content before distribution. This preliminary action creates an inherent tracking mechanism that operates independently of encryption status. Even if content is decrypted or hacked, the embedded watermark remains intact and traceable, providing security verification that precedes and survives potential security breaches.
3Adaptability or versatility
If media content is made widely accessible, then user convenience is improved, but ability to trace unauthorized distribution deteriorates
Solution Approach 1:
The system embeds unique, location-specific digital watermarks into media content distributed to different users or groups. Each watermark contains localized identification information specific to the receiving endpoint or distribution channel. This local quality approach enables widespread distribution with customized tracking identifiers, allowing content providers to trace unauthorized distributions back to specific users or locations while maintaining broad accessibility.

AI summary
This disclosure describes systems and methods related to utilizing hardware assisted protection for media content. In some embodiments, a provided method comprises: receiving, from a content server and by a computing device processor of a secure enclave of a device, first encrypted media content; decrypting, by the computing device processor, the first encrypted media content using a first decryption key; generating, by the computing device processor, a second decryption key; encrypting, by the computing device processor, the first decrypted media content using the second key, thereby resulting in second encrypted media content; and sending, by the computing device processor and to one or more graphical processing units (GPUs) comprised in a graphics component of the device, the second encrypted media content and the second decryption key.
