Permission-Based Media Sharing via Cloud Intermediary Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively manage the sharing of media content by minors or vulnerable individuals, as they often require supervision or permission from caretakers, leading to work-arounds that compromise privacy and convenience.
Innovation Solution
A system involving clearing devices and a cloud service that verifies and manages content sharing requests, using encryption and approval mechanisms to ensure secure and permission-based sharing, with options for automatic approval for identical or similar content, and geo-location or time-based rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content sharing is restricted to protect minors' privacy, then privacy protection is improved, but content sharing capability deteriorates
Solution Approach 1:
A cloud service acts as an intermediary between the minor's device and the caretaker's device. The cloud service receives content from the minor, encrypts it, stores it temporarily, and facilitates controlled sharing with the caretaker without requiring direct communication or workarounds. This mediator enables legitimate sharing while maintaining privacy protection.
Solution Approach 2:
The system performs preliminary encryption of content at the source device before transmission to the cloud service. This pre-encryption ensures that content is protected from the moment it leaves the minor's device, enabling safe sharing without requiring the minor to use alternative unprotected methods.
2Reliability
If manual approval processes are implemented for content sharing, then security is improved, but processing time deteriorates
Solution Approach 1:
The cloud service performs preliminary encryption and preparation of content before approval is needed. When a caretaker approves content, the pre-prepared encrypted content can be quickly released for sharing, reducing the time loss associated with manual approval processes while maintaining security.
Solution Approach 2:
The system enables automated approval workflows where pre-configured content types or previously approved content can be automatically shared without requiring manual caretaker intervention each time. This self-service capability reduces processing time for routine sharing while maintaining security for sensitive content.
3Reliability
If encryption is applied to all shared content, then security is improved, but system complexity deteriorates
Solution Approach 1:
The cloud service acts as an intermediary that handles all encryption operations. Individual devices (minor's device and caretaker's device) only need to interact with the cloud service, which manages the complex encryption and decryption processes. This centralizes complexity in the cloud service while keeping individual devices simple.
Solution Approach 2:
The cloud service creates and manages encrypted copies of content, allowing the original unencrypted content to remain on the minor's device. This copying approach enables security without requiring the original device to handle complex encryption/decryption operations, as the cloud service manages the encrypted versions.

AI summary
Embodiments of a system and method for sharing media content are generally described herein. A method may include receiving, from a first clearing device, a first indication of approval for sharing media content from an originating device, the first indication identifying the originating device, sending an encryption key for sharing the media content to the originating device, receiving an encrypted file, the encrypted file including the media content encrypted using the encryption key from the originating device, sending the encryption key and the encrypted file to a second clearing device, receiving, from the second clearing device, a second indication of approval for viewing media content, the second indication identifying a destination device, and sending, in response to receiving the second indication of approval, the encryption key and the encrypted file to the destination device.
