MFP Credential Cache for Faster Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction peripherals (MFPs) face prolonged authentication times due to the need to support multiple authentication methods, which often require software updates and involve communication hops to external systems, leading to slower login processes.
Innovation Solution
Implementing a cache on the MFP that stores a list of authorized users, allowing for local authentication using biometric identifiers, thereby reducing the need for external communication and speeding up the login process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric verification or multifactor authentication is implemented, then authentication security is improved, but authentication time increases
Solution Approach 1:
The system performs preliminary actions by pre-provisioning user credentials and authentication data directly on the MFP device before the user needs to authenticate. This allows the MFP to independently verify user credentials without needing to communicate with external authentication servers during the login process, thereby maintaining security while significantly reducing authentication time.
2Adaptability or versatility
If multiple authentication methods are added to support various users, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complexity of supporting multiple authentication methods from the MFP device itself and relocates it to the credential provisioning process. The MFP maintains a simple verification mechanism while the complexity of supporting various authentication types (biometric, multifactor, etc.) is handled during the initial credential setup phase, allowing the device to support multiple methods without increasing operational complexity.
3Extent of automation
If authentication is performed through external authentication systems, then centralized control is improved, but communication hops increase leading to slower login
Solution Approach 1:
The system performs preliminary provisioning of authentication credentials directly on the MFP device before the user needs to login. This pre-positioning of authentication data allows the MFP to independently verify user credentials without needing to communicate with external authentication servers during the actual login process, thereby maintaining centralized control through the initial provisioning while eliminating communication delays during authentication.
Solution Approach 2:
The MFP acts as an intermediary that holds and verifies user credentials locally. Instead of requiring direct communication between the user and external authentication systems, the MFP mediates the authentication process by independently verifying credentials that were previously provisioned, thereby reducing communication hops and improving login speed while maintaining centralized authentication control through the initial credential distribution.
Data Source
AI summary
A method, a non-transitory computer readable medium, and a multifunction peripheral or multifunction printer that includes a method for enhanced authentication. The method includes: receiving authentication information from a client device on a computer system; comparing the authentication information received from the client device to authentication information in a list of authorized users hosted in a cache of the computer system; and authenticating a user for access to the computer system when the authentication information received from the client device corresponds to the authentication information associated with the user in the list of authorized users in the cache of the computer system.
