Secure Video Player Reconstructing Face Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are ineffective in reliably detecting and preventing the creation of synthetic media, such as deepfake videos, which can be misleading and difficult to recognize, as they lack the capability to securely manage and protect original video content needed for synthetic media creation.
Innovation Solution
The system extracts and securely stores face portions from videos, linking them to the original video source using private and public keys, allowing only authorized media players to access and combine the protected face portions with the remaining video stream to display a securely reconstructed video, preventing the misuse of original content for synthetic media creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face portions are extracted and securely stored with private keys, then protection against synthetic media creation is improved, but system complexity increases due to key management and video reconstruction requirements
Solution Approach 1:
The video is segmented into two distinct parts: face portions containing identifiable features and remaining portions without faces. Face portions are extracted, encrypted with private keys, and stored separately in a secure database, while remaining portions are stored publicly. This segmentation enables protection against synthetic media creation while managing system complexity through structured data organization.
Solution Approach 2:
A media player acts as an intermediary component that receives both encrypted face portions and remaining portions, decrypts the face portions using associated public keys, and combines them to reconstruct the complete video. This intermediary handles the complexity of key management and video reconstruction, isolating it from both storage and playback systems.
2Reliability
If face portions are removed from public media streams, then prevention of synthetic media creation is improved, but video completeness deteriorates for unauthorized viewers
Solution Approach 1:
Instead of permanently removing face portions from the video, the system creates separate copies: encrypted face portion files stored in a secure database and remaining video portions stored publicly. Authorized media players retrieve and combine these copies to reconstruct the complete video, ensuring video completeness is preserved for legitimate viewers while preventing unauthorized synthesis.
3Reliability
If encrypted face portions are provided only to authorized media players, then access control is improved, but ease of operation deteriorates due to authentication requirements
Solution Approach 1:
The media player system incorporates built-in authentication and decryption capabilities that automatically verify authorization and reconstruct videos without requiring manual intervention. The media player self-manages the process of retrieving encrypted face portions, decrypting them using stored public keys, and combining them with remaining video portions, making the system easy to operate despite having robust access control.
Data Source
AI summary
A secure media hosting system stores a protected portion of an audio-video (AV) recording, a private key associated with the AV recording, and a mask identifier. A media player device is communicatively coupled to the secure media hosting system. The media player device receives a media stream that includes a first portion of an AV recording, a public key corresponding to the AV recording, and the mask identifier. The public key and mask identifier are extracted from the media stream. A request for the protected portion of the AV recording is provided. The request includes the extracted public key and mask identifier. After providing the request for the protected portion of the AV recording, the protected portion of the AV recording is received. The first portion and protected portion of the AV recording are combined. The combined first and protected portions of the AV recording are displayed.
