Tracker Server Database for P2P Content Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current P2P protocols lack the ability to efficiently distinguish between legitimate and illegitimate traffic, leading to potential malware distribution and unauthorized copyright exchanges, which harms network bandwidth and Quality of Experience for users, prompting a need for a system that can classify and manage P2P content effectively.
Innovation Solution
A database is created that maps metadata to P2P content using unique keys, allowing for the identification and classification of P2P files, enabling Internet Service Providers to manage illegitimate traffic while preserving bandwidth and preventing copyright infringement without disrupting legitimate transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If P2P protocols are used for decentralized content sharing, then users can access and share content freely, but there is no way to verify that users are downloading desired content or that content is legitimate
Solution Approach 1:
The patent introduces a tracker server as an intermediary component in the P2P network. The tracker server receives torrent files from peers, indexes their metadata including content hashes and descriptions, and provides this indexed information back to requesting peers. This mediator enables content verification without requiring direct peer-to-peer verification mechanisms.
Solution Approach 2:
The system performs preliminary indexing of torrent file metadata at the tracker server before peers attempt to download content. By pre-processing and storing information about available content (including hashes for verification), the system enables peers to verify content legitimacy before initiating downloads, preventing malware distribution and unauthorized exchanges.
2Object-affected harmful factors
If ISPs block all P2P traffic to prevent copyright infringement and malware, then network security improves, but legitimate P2P transfers are also disrupted
Solution Approach 1:
The patent enables differentiated treatment of P2P traffic based on content characteristics. By indexing torrent metadata at the tracker server, the system allows ISPs to identify and manage only illegitimate traffic (containing malware or copyrighted material) while allowing legitimate traffic to proceed unimpeded. Each torrent file receives appropriate management actions based on its classified content type.
Solution Approach 2:
The tracker server provides feedback to ISPs about the nature of P2P traffic by maintaining an indexed database of torrent metadata. This feedback mechanism enables ISPs to make informed decisions about traffic management, allowing them to block specific illegitimate torrents while permitting legitimate content sharing to continue.
3Adaptability or versatility
If torrent files are not indexed, then P2P network decentralization is maintained, but peers cannot be certain that torrent files will result in retrieving desired content
Solution Approach 1:
The tracker server performs multiple functions within the P2P network: it facilitates peer connections, indexes torrent metadata, verifies content hashes, and provides this information to peers. By consolidating these functions at the tracker, the system maintains decentralized peer-to-peer content transfer while centralizing the information management needed for content verification.
Data Source
AI summary
Various exemplary embodiments disclose an apparatus and method for generating a database that maps metadata to peer-to-peer (P2P) content and, more particularly, to a database that an Internet Service Provider (ISP) can build to correlate metadata with P2P traffic. The database may collect metadata having a key that uniquely corresponds to particular P2P content. An ISP may use the database to identify malware in P2P files and tag P2P traffic that seeks to exchange material in violation of applicable copyright laws.
