Secure Content Sharing with Encrypted Groups and Adaptive Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for sharing photographs and videos fail to provide a secure, well-defined, and recurring system for instant distribution and sharing, inadequately enabling users to selectively share galleries of multiple items of content and lacking easy-to-use content sharing interfaces across chained social networks.
Innovation Solution
A system and method for secure content storage and delivery that includes a computer system with network interface and storage, enabling users to define groups, encrypt data, and synchronize content in real-time across devices, using transcoding and down sampling to optimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques are used for sharing photographs and videos, then users can share content, but the system lacks security and fails to provide a well-defined recurring system for instant distribution
Solution Approach 1:
The system segments content sharing into distinct functional components: content capture/upload module, secure repository module, distribution module, and synchronization module. Each component handles specific tasks independently, improving security through modular architecture while maintaining system manageability.
Solution Approach 2:
A secure repository acts as an intermediary between content creators and distributors. The repository receives, stores, and manages content securely, then distributes it through controlled channels. This intermediary layer provides well-defined access controls and audit trails without requiring direct peer-to-peer sharing infrastructure.
2Adaptability or versatility
If content is distributed across multiple devices and platforms, then sharing capability is enhanced, but network and processor bandwidth consumption increases
Solution Approach 1:
Instead of transmitting full-resolution content to all devices, the system creates and distributes thumbnail copies for preview purposes. Full-resolution content is only transmitted when explicitly requested by the user. This copying strategy enables widespread distribution across multiple devices while minimizing network bandwidth consumption.
Solution Approach 2:
The system implements local quality adaptation by providing different quality levels of content to different devices based on their capabilities and network conditions. Thumbnails are provided universally for interface display, while full-resolution content is delivered only to devices that request it and have adequate network resources.
3Speed
If real-time synchronization is implemented across large numbers of systems, then content freshness is improved, but processor and network bandwidth usage increases
Solution Approach 1:
The system implements periodic synchronization intervals rather than continuous real-time updates. Devices check for content updates at predetermined intervals and synchronize when changes are detected. This periodic approach maintains content freshness across the distributed system while significantly reducing processor and network bandwidth consumption compared to continuous synchronization.
Solution Approach 2:
The synchronization system operates autonomously by monitoring for changes at the secure repository and automatically initiating updates only when necessary. Devices self-manage their synchronization state, requesting updates only when the repository indicates new content is available, thereby reducing unnecessary processor and network resource consumption.
4Reliability
If encryption is applied to sensitive data, then security is improved, but processing overhead increases
Solution Approach 1:
The system applies encryption selectively to sensitive data elements rather than encrypting all content uniformly. Metadata and non-sensitive content are handled with minimal or no encryption, while personally identifiable information and sensitive content receive full encryption protection. This localized encryption approach maintains security for critical data while preserving processing efficiency for non-sensitive operations.
Data Source
AI summary
A group definition is received via a network interface. Communications are transmitted to destinations, the communications comprising an invitation to associate with the a content sharing group. Authentication data associated with users that accept the invention is encrypted. The accepting users are associated with the content sharing group. A content gallery definition is received. A communication is received that the content gallery is to be shared with the content sharing group. The content gallery is caused to be instantiated on devices of users associated with the group. A content request for the content sharing group is received and the content request is transmitted accordingly to users associated with the group. A content item is received in response the request and the content item is transmitted to user devices associated with the group and enabled to appear in instantiations of the content gallery on the user devices.
