Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting unwanted message flooding, such as spam and rumors, in messaging networks are inadequate as they rely on snapshot data analysis and fail to effectively identify clusters over time, leading to delayed detection and corrective actions.
Innovation Solution
The application of unsupervised clustering algorithms like DBSCAN on real-time big data streams, combined with graph processing algorithms, to analyze clusters of messages and identify loops, enabling real-time detection and visualization of spam, and implementation of automated actions to block senders and content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If snapshot data analysis is used for spam detection, then the detection method is simple and fast, but it fails to identify clusters that spread over time and results in delayed detection
Solution Approach 1:
The patent transitions from static snapshot analysis to dynamic streaming analysis. The system continuously processes message data streams in real-time, updating cluster assignments as new messages arrive. This dynamic approach allows the system to detect clusters that evolve over time, resolving the contradiction between detection speed and accuracy by maintaining continuous awareness of message patterns without requiring periodic snapshots.
Solution Approach 2:
The patent implements continuous clustering analysis on streaming data rather than periodic snapshot analysis. The DBSCAN clustering algorithm operates continuously on incoming message streams, maintaining cluster structures and updating assignments in real-time. This continuous operation ensures that clusters spreading over time are detected as they form, eliminating detection delays while maintaining analytical precision.
2Measurement precision
If real-time streaming clustering is implemented, then detection accuracy and real-time identification are improved, but computational complexity and processing requirements increase
Solution Approach 1:
The patent segments the continuous streaming data into manageable time-based batches or windows for processing. By dividing the stream into discrete segments, the system can apply clustering algorithms to smaller, more manageable data portions while maintaining real-time detection capabilities. This segmentation reduces the computational burden on any single processing step while preserving the ability to detect time-evolving clusters.
Solution Approach 2:
The patent applies partial clustering by focusing computational resources on identifying and maintaining only the most relevant clusters that meet certain criteria (e.g., minimum size, growth rate thresholds). Rather than clustering all possible message combinations, the system performs partial analysis on subsets of data that are most likely to contain spam patterns, reducing overall computational complexity while maintaining detection accuracy for malicious clusters.
3Reliability
If message data is continuously analyzed in real-time streams, then clusters spreading over time are detected, but data processing load and resource consumption increase
Solution Approach 1:
The patent implements partial analysis by applying clustering algorithms only to message subsets that meet specific criteria, such as messages containing certain keywords, from particular senders, or exhibiting suspicious patterns. This selective processing reduces the overall data volume requiring intensive analysis while maintaining reliable detection of spam clusters, thereby lowering energy consumption without compromising detection reliability.
Solution Approach 2:
The patent discards messages that have been processed and determined to be benign or already accounted for in existing clusters. By identifying and eliminating redundant or non-threatening messages from further processing, the system reduces the continuous data processing load and associated energy consumption while maintaining reliable detection of new or evolving spam clusters through ongoing stream analysis.
Data Source
AI summary
Detecting and restricting floods of unwanted messages is implemented by cluster analysis over time intervals. Application of streaming machine learning clustering algorithms enables finding clusters of messages (P2P text messages, WHATSAPP, tweets) sharing the same content. Such clusters may be analyzed for finding out offensive messages, unwanted or spam messages, and rumors and take corrective actions as needed. The solution enables visualization of data and/or messages and identification of clusters as the solution works on the data and aggregates data into clusters over time intervals. Corrective actions may be applied on selected clusters based on visualized data clusters or by automated application of defined rules.
