Smart Meetup Location Selection for Secure Peer-to-Peer Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online marketplaces face challenges in ensuring secure in-person transactions between strangers for second-hand goods sales, as they lack the ability to guarantee the intentions of users and ensure safety during meetups, leading to risks associated with meeting strangers.
Innovation Solution
A system that determines a 'smart' meetup location for users based on their current device locations without disclosing their actual positions, offering varying security levels and convenience, by using a host platform to select a secure location from predefined safe areas, such as government buildings or restaurants, and providing route information to users while maintaining their privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users meet in-person for second-hand goods exchange, then shipping costs are saved and transaction speed increases, but user safety risks increase due to meeting strangers
Solution Approach 1:
The patent introduces a third-party intermediary location (the selected meetup point at a business establishment) that mediates between the buyer and seller. This intermediary space allows strangers to conduct transactions safely without directly exposing their personal locations or identities, thus reducing safety risks while maintaining fast in-person exchange
Solution Approach 2:
The system creates a virtual copy of location information through the online marketplace platform. Instead of sharing real geographical coordinates or personal addresses, users interact through the platform's digital interface which replicates location data in a secure, anonymized manner, enabling safe meetup arrangement
2Object-affected harmful factors
If online marketplace hides user geographical locations, then user privacy and safety are protected, but users cannot determine convenient meetup locations
Solution Approach 1:
The online marketplace platform acts as an intermediary that receives location preferences from both users, processes this information through its system, and returns a mutually convenient meetup location without exposing actual user locations. This mediator role enables location determination while maintaining privacy
Solution Approach 2:
The system transforms location data from precise geographical coordinates into generalized area preferences or radius-based selections. By changing the parameter precision of location information, the system enables meetup coordination while protecting user privacy through reduced location granularity
3Ease of operation
If users share actual location information to find convenient meetup points, then meetup convenience increases, but user safety risks increase due to location disclosure
Solution Approach 1:
The system changes the parameter of location information from precise coordinates to generalized area preferences or distance radii. Users specify acceptable distance ranges or area preferences rather than exact locations, enabling convenient meetup determination while preventing precise location disclosure and associated safety risks

AI summary
Provided are systems and methods for providing a smart meetup location to a plurality of user devices. In one example, the method may include one or more of receiving a request for a meetup location of a first user device and a second user device, dynamically determining a geographical position of the first user device based on current location information of the first user device, dynamically determining a geographical position of the second user device based on current location information of the second user device, selecting a meetup location from among a plurality of meetup locations based on the dynamically determined geographical positions of the first and second user devices, and outputting the selected meetup location to at least one of the first and second user devices.
