1  DRM for Digital Holographic Content

• Applies conditional proxy re-encryption to control and verify licenses throughout the content lifecycle — from upload and sale, to purchase, decryption, and final printing.

 2  End-to-End Copyright Supply Chain Management

• Manages the full lifecycle of digital holographic content, including creation, distribution, and printing, ensuring traceability and integrity.

 3  High-Speed Fringe Pattern Encryption with Multi-GPU Support

• Utilizes AES-CTR algorithms with multi-GPU parallel processing to enable fast encryption and decryption of large-volume holographic data. 

 

 1  Prevention of Large-Scale Content Leakage

• Enables secure distribution and protects against unauthorized access to high-resolution holographic content through fast and scalable multi-GPU encryption.

 2 ​ Tamper-Proof License Verification

• Prevents license forgery by managing the production and distribution history on a blockchain-based supply chain system.

 3  Protection of Original Content on Servers

• Implements an on-off chain structure with proxy re-encryption to ensure that original server content remains inaccessible and fully encrypted throughout the process.
