Location-Based Content Sharing System Using Server Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current social network services lack the ability to effectively provide content to users based on their location, making it difficult for users to find relevant information or services around them.
Innovation Solution
A system and method that utilizes location information to share messages and content by generating and transmitting post metadata from an upload terminal to a server, which verifies and stores the content, and then provides it to download terminals within a predetermined distance from the user's location, allowing users to receive desired content based on their location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If location-based content sharing is implemented, then users can receive relevant messages and content based on their location, but the system complexity increases due to the need for location verification and distance calculation
Solution Approach 1:
The server acts as an intermediary between upload terminals and download terminals, centralizing the location verification and content matching process. The server receives location information from download terminals, verifies post metadata including location data from upload terminals, calculates distances, and selectively provides content based on predetermined distance thresholds. This mediator approach resolves the contradiction by handling the complex location-based filtering centrally, keeping individual terminals relatively simple while ensuring high content relevance through systematic location verification.
2Ease of operation
If content is provided to all users regardless of location, then the system is simple to operate, but users cannot find relevant information or services around them
Solution Approach 1:
The system performs preliminary location verification and distance calculation before content delivery. When upload terminals share content, the server pre-verifies the post metadata including location information and stores it alongside the content. When download terminals request content, the server quickly matches their location against the pre-verified location data and distance thresholds, eliminating the need for complex real-time filtering and maintaining operational simplicity while ensuring content relevance.
3Loss of information
If location verification and distance calculation are performed, then content relevance is improved, but the processing time and energy consumption increase
Solution Approach 1:
The server performs location verification and distance calculation in advance when content is uploaded, storing the verified location metadata and distance thresholds with the content. This preliminary processing eliminates the need for time-consuming real-time location analysis when users request content, as the server can quickly match pre-calculated location data against user positions, maintaining content relevance while minimizing delivery time.

AI summary
A system and method for sharing a message and/or content using location information. The system for sharing a message and/or content includes at least one upload terminal that generates and transmits post metadata including a message/content prepared for uploading, location of the upload terminal, and location for uploading the prepared message/content thereto; a download terminal that transmits a connection message including current location, and downloads message/content posted within a predetermined distance from the current location to display the posted message/content; and a server that verifies the post metadata by receiving the prepared message/content and the post metadata corresponding to the prepared message/content from the upload terminal, stores a result of verification, searches for the prepared message/content to be provided to the download terminal when the connection message including the location is received from the download terminal, and provides information on the searched message/content and post location to the download terminal.
