Broadcast Message Targeting Using Bloom Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast messaging methods lack the ability to target messages to specific subsets of receivers, leading to inefficiencies in resource usage and bandwidth consumption, especially when sending messages to large numbers of receivers.
Innovation Solution
A system and method that embeds a set data structure, such as a Bloom filter, into broadcast messages, allowing receivers to determine if their identifying information is part of the target set, enabling targeted message delivery without prior communication and conserving bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If broadcast messaging is used to send messages to all receivers, then message delivery coverage is maximized, but bandwidth consumption and resource usage increase significantly when targeting large numbers of receivers
Solution Approach 1:
The patent segments the receiver population into targeted subsets using set data structures (Bloom filters) embedded in broadcast messages. Instead of treating all receivers uniformly, the system divides receivers into specific target groups and sends tailored messages only to those groups, thereby reducing unnecessary bandwidth consumption while maintaining effective message delivery to the intended audience.
Solution Approach 2:
The patent introduces set data structures (Bloom filters) as intermediary elements between the message sender and receivers. These intermediaries enable selective message delivery by allowing receivers to determine whether they should process the message based on their membership in the target set, thus reducing bandwidth consumption without requiring complex point-to-point addressing infrastructure.
2Measurement precision
If point-to-point messaging is used to send messages to specific receivers, then message targeting precision is improved, but resource consumption increases when the number of designated receivers is large
Solution Approach 1:
The patent uses Bloom filters as compressed copies of receiver identification data. Instead of transmitting complete receiver lists or individual addresses for each point-to-point message, the system creates a compact bitset representation that can be efficiently processed by receivers to determine membership, thereby maintaining targeting precision while significantly reducing resource consumption for large-scale message delivery.
3Ease of operation
If traditional broadcast messaging is used without targeting mechanisms, then implementation simplicity is maintained, but the ability to limit messages to specific subsets of receivers is lost
Solution Approach 1:
The patent makes traditional broadcast messaging multi-functional by embedding set data structures (Bloom filters) within the broadcast message format. This allows the same basic broadcast mechanism to serve both universal broadcasting and targeted messaging functions, maintaining implementation simplicity while adding sophisticated targeting capabilities through the universal applicability of Bloom filter-based filtering.
Data Source
AI summary
A system for and method of targeting a broadcast message to a subset of potential electronic receivers in a broadcast network is presented. The system and method may comprise collecting identifying information associated with designated electronic receivers of a targeted broadcast message, generating, using a computer processor, a data set structure using the identifying information, associating the data set structure with the targeted broadcast message, and broadcasting the targeted broadcast message and the data set structure to a plurality of electronic receivers, wherein the data set structure provides information allowing at least one of the plurality of electronic receivers to determine whether the targeted broadcast message is targeted to the at least one electronic receiver.
