Digital Media Content Blocking via Deep Packet Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing unauthorized digital media replication, such as DNS blocking and deep packet inspection, often unintentionally block valid websites and IP addresses and fail to accurately identify unauthorized content types.
Innovation Solution
A system and method that uses a detection hardware device with a processor to detect user requests for digital media, verify network traffic, query a database for legitimate connections, and monitor content for authorization, disabling unauthorized content from executing on user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DNS blocking is used to prevent unauthorized media replication, then access to unauthorized websites is blocked, but valid websites with similar domain names are unintentionally blocked
Solution Approach 1:
The patent replaces DNS blocking (mechanical/domain-level filtering) with deep packet inspection (content-level analysis). Instead of blocking based on domain names or IP addresses, the system inspects the actual content of data packets to identify unauthorized media replication, thereby avoiding false blocking of valid websites while accurately targeting unauthorized content.
Solution Approach 2:
The patent applies local quality by analyzing the specific content characteristics of each data packet rather than applying uniform blocking rules. The deep packet inspection examines the actual media content, user authentication status, and usage patterns to determine whether each specific instance of media access is authorized, allowing differentiated treatment of authorized and unauthorized content.
2Measurement precision
If deep packet inspection is used to monitor data packets, then content identification improves, but processing complexity and time increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing user authentication status and media licensing information in databases before the deep packet inspection occurs. When packets arrive, the system can quickly reference pre-processed authentication data rather than performing complex real-time verification, reducing the processing burden during actual content monitoring.
Solution Approach 2:
The patent segments the deep packet inspection process into multiple stages: initial packet filtering based on simple criteria (source/destination addresses), intermediate analysis of content patterns, and final verification against authentication databases. This segmentation allows the system to process packets efficiently by applying increasingly sophisticated checks only when necessary.
3Reliability
If pattern search is performed on massive amounts of data, then unauthorized content detection improves, but processing time increases
Solution Approach 1:
The patent extracts and analyzes only the critical portions of data packets that contain authentication information and content identifiers, rather than processing every byte of network traffic. By focusing inspection on specific packet fields and metadata, the system maintains high detection accuracy while significantly reducing the volume of data that requires processing.
Solution Approach 2:
The patent implements feedback mechanisms where the deep packet inspection system continuously refines its detection algorithms based on detected patterns and authentication results. This feedback loop allows the system to improve its pattern recognition over time, reducing false positives and enabling faster verification decisions as the system learns from processed data.
Data Source
AI summary
A method and system for improving a digital media content transfer blocking process is provided. The method includes detecting a request for access to digital media content from a digital media provider system. Network traffic across the network is identified and it is verified that the digital media content is comprised by the network traffic. In response, investigation platform software code is executed and a database system associated with the digital media provider system is queried. A system determines if a legitimate connection based relationship exists between a user device and the digital media provider system and the digital media content is monitored. The digital media content is determined to be unauthorized for use by the user and in response the digital media content is disabled from executing functions with respect to the user device of a user.
