Partial Encrypted Content Download for Super Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional super distribution methods face challenges in providing on-demand access to complete audio and video content due to missing portions in distributed files, which can hinder seamless playback and content rendering.
Innovation Solution
The system enables automated on-demand download and merging of partial encrypted content from a secondary file to complete the missing portions in a partial super distributed content file, using multiple encryption systems to ensure secure and efficient content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional super distribution is used to distribute A/V content to large volumes of consumers, then distribution reach is improved, but content completeness deteriorates due to missing portions in distributed files
Solution Approach 1:
The content is divided into multiple segments or portions, where the master copy contains all portions and distributed copies contain only specific portions. This segmentation allows widespread distribution while maintaining the ability to reconstruct complete content by combining multiple distributed copies with the master copy.
Solution Approach 2:
The invention implements a nested structure where distributed content portions are embedded within a hierarchical distribution system. Each distributed copy contains a subset of content that is nested within the complete master copy structure, allowing consumers to access complete content through combination while enabling broad distribution of individual portions.
2Loss of information
If automated on-demand download and merging of partial encrypted content is implemented, then content completeness is improved, but system complexity deteriorates
Solution Approach 1:
The system implements self-service automation where the content rendering device automatically detects missing portions, downloads required encrypted content portions on-demand, and merges them with the distributed copy. This automated self-service approach reduces manual intervention while managing the complexity of content reconstruction and encryption/decryption operations.
Solution Approach 2:
The master copy is prepared in advance with all content portions organized and encrypted according to the distribution scheme. This preliminary organization of content into manageable, encryptable portions simplifies the automated download and merging process at the consumer end, as the structure is already established and ready for efficient retrieval and combination.
3Reliability
If multiple encryption systems are used to secure content delivery, then security is improved, but processing time deteriorates due to decryption requirements
Solution Approach 1:
Instead of encrypting and decrypting the entire content stream, the system applies encryption only to specific portions or segments of content. This partial encryption approach maintains security for distributed content while significantly reducing the decryption processing time required, as only the missing portions need to be decrypted and merged, not the entire content.
Solution Approach 2:
Content is segmented into multiple portions with different encryption schemes applied to different segments. This segmentation allows parallel decryption processing of smaller portions rather than a single large decryption operation, reducing overall processing time while maintaining security through multiple encryption systems across different content segments.
Data Source
AI summary
A request to render content associated with a first super distributed content file is detected by a content rendering device. At least one portion of the content associated with the first super distributed content file is determined to be missing from the first super distributed content file. A second file including the at least one portion of the content missing from the first super distributed content file is obtained from a server. The at least one portion of the content of the second file includes partial encrypted portions of the content associated with an encryption system of the content rendering device. A content output stream including decrypted partial encrypted portions of the content of the second file and the content associated with the first super distributed content file is generated. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
