Account Identification Using Hierarchized Positional Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for determining whether social networking service (SNS) accounts belong to the same user are inaccurate when faced with erroneous or false information, as they rely on calculating a matching degree using associated information.
Innovation Solution
An information processing apparatus and method that acquires positional information, hierarchizes it based on granularity levels, calculates similarity between accounts using this hierarchized information, and specifies accounts belonging to the same user, thereby overcoming issues with erroneous data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information associated with identification information is used to calculate matching degree, then the determination process can be performed using available user data, but the accuracy deteriorates when erroneous or false information is present
Solution Approach 1:
The patent introduces positional information as an intermediary element to bridge the comparison between identification information. Instead of directly comparing potentially erroneous user-provided information, the system uses positional data (location coordinates, address information) as a neutral mediator that objectively reflects the user's actual location, thereby resolving the contradiction between ease of determination and accuracy.
Solution Approach 2:
The patent replaces the traditional text-based information comparison mechanism with a spatial/geographic information mechanism. By substituting the mechanical process of string matching and semantic analysis with spatial distance calculation and geographic coordinate comparison, the system achieves more accurate and reliable identification information determination that is not affected by user input errors.
2Device complexity
If traditional matching techniques are used, then the system can operate with simple comparison logic, but the reliability of identification specification deteriorates in the presence of false information
Solution Approach 1:
The patent changes the parameter space from text-based identification attributes (usernames, profile information) to spatial parameters (latitude, longitude, address coordinates). This parameter transformation allows the system to maintain relatively simple comparison logic based on distance calculations while dramatically improving the reliability of identification specification, as spatial parameters are objective and not subject to user manipulation or errors.

AI summary
An information processing apparatus capable of accurately specifying identification information whose users are the same user regardless of information registered by users is provided. The information processing apparatus may include at least one memory storing instructions and at least one processor configured to execute the instructions to: acquire positional information associated with at least one piece of related identification information related to each of a plurality of pieces of identification information for identifying users in a communication service; specify hierarchized positional information indicating positional information hierarchized in accordance with a granularity level of a position based on the positional information; calculate a similarity between pieces of identification information using the hierarchized positional information; and specify the pieces of identification information belonging to the same user from among the plurality of pieces of identification information based on the calculated similarity.
