Smart Card Certificate Mapping for Multi-Persona Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identity and access management systems face challenges in managing smart cards for users with multiple user personas, leading to complex directory maintenance and security vulnerabilities due to the inability to uniquely resolve user accounts with a single smart card.
Innovation Solution
The described techniques enable mapping a smart card to multiple user personas by comparing certificate attributes with user directory entries, allowing the identity management platform to identify and present a list of user personas for selection, thereby simplifying directory management and reducing security risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart card is mapped to a single user account in conventional identity management systems, then the directory structure remains simple and easy to manage, but users with multiple roles cannot be authenticated using a single smart card, leading to increased directory maintenance complexity and security vulnerabilities
Solution Approach 1:
The patent segments the user account structure by introducing user personas as distinct entities within the directory. Each persona represents a specific role or function, allowing a single smart card to be mapped to multiple segmented personas rather than requiring a single monolithic user account. This segmentation enables versatile authentication while maintaining organized directory structures through hierarchical relationships between users and their personas.
2Reliability
If multiple user accounts are created for users with multiple roles, then each role can be properly authenticated, but the directory becomes cluttered and harder to maintain
Solution Approach 1:
The patent merges multiple user personas under a single user record in the directory. Instead of creating separate user accounts for each role, the system combines multiple personas (each representing a specific role) under one user umbrella. This merging approach maintains authentication accuracy by preserving distinct persona identities while simplifying directory maintenance through consolidated user management and reduced redundancy.
Solution Approach 2:
The user record structure is designed to be universal, capable of holding multiple personas simultaneously. This multi-functional user record can accommodate various roles and responsibilities within a single organizational entity, eliminating the need for separate user accounts for each role while maintaining the ability to authenticate each persona independently with a single smart card.
3Productivity
If users are required to remember multiple usernames for different roles, then each user account can be accessed, but user experience deteriorates and security risks increase
Solution Approach 1:
The smart card serves as an intermediary authentication device that bridges the user and multiple personas. Instead of requiring users to remember multiple usernames, the smart card automatically presents the user's identity to the system, which then resolves the appropriate persona based on the authentication context. This intermediary mechanism simplifies user operation while maintaining authentication efficiency by eliminating manual username selection.
Data Source
AI summary
Methods, systems, and devices for mapping a smart card to multiple user personas are described. A smart card may be used for authenticating a user requesting access to a resource associated with an organization. The smart card may have embedded therein a digital certificate identifying a digital identity of the user. The user may be associated with multiple user accounts or personas in a repository, such as a user directory. Techniques may allow for the multiple user personas to be mapped to digital certificate of a single smart card and for authentication of the multiple user personas using the single smart card.
