Stepwise Service Account Authentication Combining Social and Credential Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user authentication methods for service accounts, such as those used in social network services, are inconvenient due to the need for re-authentication when terminal devices or SIM cards are replaced, and often fail when users forget their registered email addresses or passwords.
Innovation Solution
A stepwise user authentication method that combines authentication information and social information, using a manager to manage initial join details and social data, including service use information and personal relationship information, to perform authentication through a processor that organically connects multiple authentication methods and adjusts based on risk levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If telephone number-based authentication is used for service account, then account creation is simple, but re-authentication fails when terminal or SIM card is replaced
Solution Approach 1:
The authentication system is segmented into multiple independent authentication methods (telephone number authentication, email authentication, social network authentication). Each method can operate independently, and when one method fails due to terminal replacement or SIM card change, other methods remain available to maintain authentication reliability without affecting account creation simplicity.
Solution Approach 2:
The system changes the parameter of authentication information from static (single telephone number) to dynamic (multiple authentication vectors including telephone number, email, and social network data). This allows the authentication system to adapt when one parameter becomes invalid, maintaining both creation simplicity and authentication reliability.
2Reliability
If email address or password authentication is used in addition to telephone number, then authentication security improves, but user authentication fails when users forget authentication information
Solution Approach 1:
Social network authentication data acts as an intermediary authentication vector. When users forget traditional authentication information (email or password), the system uses social network authentication as a mediator to verify user identity, maintaining security while providing an alternative path that does not require remembering additional authentication credentials.
Solution Approach 2:
The authentication system achieves multi-functionality by supporting multiple authentication methods (telephone number, email, password, social network). This universal approach allows the system to serve multiple authentication needs simultaneously, providing both security through multiple vectors and convenience through fallback options when users forget authentication information.
3Reliability
If multiple authentication methods are combined, then authentication reliability improves, but authentication process complexity increases
Solution Approach 1:
The authentication process is made dynamic rather than static. The system automatically selects and sequences authentication methods based on real-time conditions (whether user has terminal, SIM card, access to email, or social network connectivity). This dynamic adaptation reduces perceived complexity by presenting only the relevant authentication path to the user at any given moment, while maintaining high reliability through multiple available methods.

AI summary
Disclosed are a method, system, and storage medium for service account authentication. A user authentication method includes managing authentication information associated with a service account of a user and social information about the user; and performing user authentication with respect to the service account through a stepwise procedure in which an authentication method using the authentication information and an authentication method using the social information are combined.
