P2P Multimedia Verification via Encrypted Entity Content Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peer-to-peer multimedia content distribution systems face challenges in secure content verification and key management, especially when users move out of network coverage areas, leading to potential unauthorized data access and service disruptions.
Innovation Solution
A method involving the generation and encryption of verification information containing entity and content identifiers, using symmetric keys derived from ciphering and integrity keys, to ensure secure content transfer and usage, even in peer-to-peer communication links beyond traditional network coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If peer-to-peer content distribution is implemented to reduce server burden and improve coverage, then system capability and network load distribution are improved, but security verification and unauthorized access control become more difficult
Solution Approach 1:
The patent applies preliminary action by generating verification information and distributing encryption keys to peer entities before actual content sharing occurs. This pre-configuration of security credentials enables automated verification during P2P transactions without requiring real-time centralized authentication, thus maintaining high system capability while ensuring security.
Solution Approach 2:
The patent introduces verification information as an intermediary element that mediates between content providers and consumers in P2P networks. This verification information, containing encrypted identifiers and content metadata, acts as a trusted intermediary that enables security verification without requiring direct connection to centralized servers during the actual content transfer.
2Area of stationary object
If users move out of network coverage areas to enable content distribution, then service coverage is improved, but authentication and key distribution become more challenging
Solution Approach 1:
The patent applies preliminary action by distributing encryption keys and generating verification information while users are still within network coverage areas. This pre-configured security material enables users to authenticate and share content securely even when moved to areas without network coverage, thus expanding service coverage without increasing authentication complexity during mobile operations.
3Reliability
If centralized servers are used to provide streaming services, then service quality is maintained, but network bandwidth demands and server costs increase linearly with user growth
Solution Approach 1:
The patent applies segmentation by dividing the centralized content distribution function into distributed peer-to-peer segments. Instead of all users connecting to centralized servers, content is segmented and redistributed among peer entities in the network. This maintains service quality through verified content sources while dramatically reducing the network bandwidth burden on centralized infrastructure.
Solution Approach 2:
The patent implements self-service by enabling peer entities to autonomously provide content to other peers using pre-distributed verification information and encryption keys. This eliminates the need for continuous centralized server involvement in each content transfer, allowing the system to scale without linearly increasing server resources or network bandwidth consumption.
Data Source
AI summary
A method includes receiving, at a first wireless device, from a second wireless device, content and an identification of the second wireless device, over a peer-to-peer wireless communication link. The received content is rendered and verification information containing the identification of the second wireless device and an identification of the received content is generated at the first wireless device. The verification information is then encrypted at the first wireless device using an encryption key. Apparatus and a computer program product counterparts to the method are also disclosed.
