Directional Media Sharing via Capture-Aware Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in efficiently sharing media content among large groups of people, particularly in crowded events, as users must manually collect contact information and send media content through conventional methods, leading to network congestion and increased usage charges, while also risking privacy.
Innovation Solution
A method where media content is captured and encrypted, then transmitted directionally using peer-to-peer or near-field communication techniques, with an encryption key sent via a different channel, allowing intended recipients to access the content from a network-based data store or directly, reducing network load and privacy risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional media sharing methods (email, MMS, peer-to-peer) are used, then media content can be shared between users, but users must manually collect contact information and know how to reach others, increasing operational complexity and time consumption
Solution Approach 1:
The system automatically performs media sharing without requiring manual contact information collection. The camera device captures media, determines capture direction, and automatically transmits to devices in that direction through directional transmission, eliminating the need for users to manually gather contact information or know how to reach others.
Solution Approach 2:
The system performs preliminary actions by determining the capture direction before transmission occurs. The camera device analyzes the direction from which media content is captured and pre-configures the transmission path accordingly, so that when transmission is initiated, the media is automatically routed to the correct receiving devices without requiring additional user input or contact information exchange.
2Productivity
If media content is transmitted through conventional networks, then media can be shared with others, but network congestion and increased usage charges occur
Solution Approach 1:
The system applies local quality by using directional transmission to send media content only to specific receiving devices in the capture direction rather than broadcasting to all devices. This localized transmission approach ensures that network bandwidth is consumed only for the intended recipients, reducing overall network congestion and usage charges while maintaining efficient media sharing productivity.
3Productivity
If media content is shared through conventional methods, then media can be transmitted to others, but privacy risks increase due to lack of directional control
Solution Approach 1:
The system implements local quality through directional transmission that targets only specific receiving devices based on the capture direction. This ensures that media content is transmitted privately to intended recipients only, preventing unintended exposure to other devices or users, thereby eliminating privacy risks associated with conventional broadcasting methods while maintaining full media sharing capability.

AI summary
Methods for processing a media content are disclosed. For example, a method captures the media content, determines a direction from which the media content is captured, encrypts the media content, and sends the media content that is encrypted toward a receiving device in the direction from which the media content was captured. Another method captures the media content, determines a direction from which the media content is captured, encrypts the media content and uploads the media content that is encrypted to a data store. The method then sends a notification toward a receiving device in the direction from which the media content was captured. The notification identifies that the media content that is encrypted has been uploaded to the data store.
