Social Network Service Emotion Visualization and Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Social Network Service (SNS) applications inadequately express user emotions and suffer from privacy infringement due to the recording of all conversation content, leading to inaccurate emotional delivery and potential leakage of personal information.
Innovation Solution
A method and apparatus for providing a social network service that allows users to create chat rooms based on location, enabling visualization and expression of emotions through advanced messaging features like emotional signatures, and includes features for secure message deletion and encryption, such as the DaVinci function, to enhance privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional SNS applications record all conversation content, then complete communication history is maintained, but privacy is infringed and personal information may leak
Solution Approach 1:
The patent implements automatic deletion of conversation records after a predetermined time period. The server and user equipment both delete message contents from their storage, ensuring that communication history is not permanently retained. This resolves the contradiction by discarding the conversation history (improving privacy) while still allowing complete communication during the active period (maintaining information availability for communication purposes).
Solution Approach 2:
The patent treats message contents as temporary, disposable data that serves its purpose during the communication period and then is deleted. Rather than maintaining permanent records, the system allows messages to exist only for the duration needed for communication, after which they are automatically removed from servers and user equipment, eliminating privacy risks associated with long-term storage.
2Ease of operation
If conventional SNS applications use pre-formed emoticons and text, then communication is simple, but user emotions cannot be expressed accurately
Solution Approach 1:
The patent replaces the mechanical system of selecting from pre-formed emoticons with a biosensing system that automatically detects user emotional states through physiological signals (facial expressions, voice tone, heartbeat). This substitution maintains ease of operation (no manual emoticon selection needed) while dramatically improving emotion expression accuracy by capturing real-time biological data that reflects genuine emotional states.
Solution Approach 2:
The system enables self-service emotion expression by automatically analyzing the user's physiological signals and generating appropriate emotional representations without requiring manual input. The biosensors continuously monitor the user's emotional state and the system automatically selects and transmits the corresponding emotional data, making the process both simple for the user and accurate in representing their true emotions.
3Object-affected harmful factors
If location-based chat room creation is implemented, then privacy protection is enhanced through selective communication, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by obtaining user location information and automatically filtering potential communication partners based on proximity before the actual communication occurs. The server pre-processes location data to identify users within the predetermined distance range, so when a user initiates communication, only compatible nearby users are presented as options. This preliminary filtering enhances privacy by preventing unwanted contact from distant users while managing complexity through automated server-side processing rather than complex client-side logic.
Data Source
AI summary
A social network service, which can visualize and express a user's emotions or opinions and can randomly arrange or permanently delete the content of conversations exchanged between the user and counterparts includes: receiving a chat room creation request from at least one user equipment; transmitting information on a user equipment that has transmitted a chat room participation request, among at least one other user equipment located within a predetermined distance from the user equipment that has transmitted the chat room creation request, to the user equipment that has transmitted the chat room creation request; and creating a chat room for allowing the user equipment that has transmitted the chat room creation request and at least one other user equipment that has transmitted a chat room participation request to perform messaging communication.
