Message Filtering Electronic Device Using Segmented Source Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message filtering methods in electronic devices are ineffective in accurately distinguishing between necessary and spam messages, as they can be easily bypassed by changes in registered spam information, leading to users being inadvertently exposed to altered spam messages, and the filtering criteria vary by user preferences and context.
Innovation Solution
An electronic device method that receives messages, checks if the source information is registered in a message source list, and if not, stores the message in an unregistered message box, allowing users to manage and display only registered messages, with options to update the list and configure filtering settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If message filtering is implemented using registered spam information, then spam messages can be blocked, but the filtering can be easily bypassed by changing the registered spam information
Solution Approach 1:
The patent segments message filtering into multiple independent dimensions: sender information filtering, message content filtering, and message type filtering. Each dimension operates with its own registered information list, so that spam messages cannot bypass all filters by simply changing one piece of information. The segmentation creates multiple barriers that work together to improve filtering reliability.
Solution Approach 2:
The patent performs preliminary registration of spam patterns across multiple dimensions (senders, content keywords, message types) before actual message filtering occurs. This preliminary action builds a comprehensive defense system that can recognize and block spam messages even when they attempt to bypass single-dimension filters by changing their characteristics.
2Reliability
If strict filtering based on registered spam information is applied, then spam messages are blocked, but important messages from unregistered senders may be missed
Solution Approach 1:
The patent applies different filtering strictness levels to different message characteristics. Messages that match multiple spam dimensions are blocked with high confidence, while messages that match only one dimension or have ambiguous characteristics are subjected to less strict filtering or placed in a review category. This local quality approach ensures that important messages are not mistakenly blocked while maintaining strong spam filtering.
3Adaptability or versatility
If message filtering is customized per user preferences, then user-specific spam can be blocked, but the system complexity increases
Solution Approach 1:
The patent creates a universal filtering framework that handles multiple filtering dimensions (sender, content, type) and multiple user preferences within a single integrated system. The same core filtering mechanism serves all users and all message types, reducing overall system complexity while maintaining high adaptability to individual user needs and preferences.

AI summary
Disclosed herein are an electronic device and a method for processing messages. The electronic device includes a display unit, a communication unit configured to receive a message from an external device, a storage unit storing a message source list and an unregistered message box, and a control unit configured to determine whether source information of the received message is registered in the message source list, if the source information is not registered in the message source list, store the message in the unregistered message box, and if the source information is registered in the message source list, display by the display unit at least a part of the received message.
