Message Augmentation for Spam Identification via Network Node Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate in effectively identifying and isolating spam messages across various networked communications, leading to unwanted traffic and annoyance for recipients and network operators.
Innovation Solution
A system that augments messages with network node attributes by linking from an original network node to additional nodes, generating message signatures to characterize the message, and evaluating these signatures to determine if the message is spam, using techniques such as DNS lookups and recursive linking to expand relationships and identify spam characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current spam identification methods are used, then basic filtering is achieved, but spam identification accuracy is insufficient leading to unwanted traffic
Solution Approach 1:
The patent segments the spam identification process into multiple independent components: extracting original network nodes from messages, augmenting with additional network node attributes through DNS lookups and recursive linking, generating separate message signatures for different attributes, and evaluating multiple signatures independently. This segmentation allows each component to be optimized separately, improving overall identification accuracy while maintaining efficient spam filtering.
2Reliability
If basic message filtering is applied, then processing speed is maintained, but identification reliability is insufficient
Solution Approach 1:
The patent performs preliminary actions by extracting and augmenting network node attributes before message evaluation. DNS lookups and recursive linking are conducted in advance to build a comprehensive profile of network nodes associated with the message. This preliminary augmentation ensures that when messages are evaluated, reliable identification can be made based on pre-computed network node attributes, improving reliability without significantly increasing real-time processing complexity.
3Measurement precision
If network node attributes are augmented through DNS lookups and recursive linking, then message characterization is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by selectively performing DNS lookups and recursive linking based on message characteristics and risk levels. Not all messages undergo the full augmentation process; instead, the system performs augmentation selectively to achieve sufficient message characterization precision while limiting the time loss to only those messages that require enhanced analysis. This partial application of the augmentation process optimizes the balance between precision and processing time.

AI summary
A computer includes a processor and a memory connected to the processor. The memory stores instructions executed by the processor to augment a message with network node attributes derived by linking from an original network node specified in the message to additional network nodes associated with the original network node. Message signatures representing the network node attributes are generated. The message signatures are evaluated to characterize the message.
