Document-Processing Device Access via Authentication Token
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling access to document-processing devices, such as printers and scanners, are cumbersome and insecure, requiring users to remember and manually input usernames and passwords, which can be frustrating and vulnerable to unauthorized access.
Innovation Solution
Implementing a system that uses a portable authentication token, such as a proximity card, smart card, or cell phone, to manage access to document-processing devices, where the device reads authentication data to verify user privileges and grant access, reducing the need for manual input and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If username and password combination is used for access control, then security can be maintained, but user convenience deteriorates due to the need to remember and manually input credentials
Solution Approach 1:
The system uses automatic authentication where the document-processing device automatically reads authentication data from a token when a user approaches, eliminating the need for manual password entry. The device self-verifies user privileges without requiring user intervention in the authentication process.
Solution Approach 2:
The patent replaces the mechanical/manual system of typing and remembering passwords with an automated optical/electromagnetic reading system. The device uses optical or electromagnetic fields to read authentication data from a token automatically, substituting manual input with automated detection.
2Productivity
If username and password combination is used for access control, then access management is possible, but time consumption increases due to manual input requirements
Solution Approach 1:
The system performs preliminary authentication by having the device automatically read and verify authentication data from the token before the user needs to access any functions. This pre-authentication eliminates the time-consuming manual entry process during actual usage.
Solution Approach 2:
The authentication process becomes continuous and automatic - the device continuously monitors for user approach and automatically performs authentication without interruption to the user's workflow, eliminating pauses for manual credential entry.
3Reliability
If information-based authentication (username/password) is used, then access control is achieved, but security vulnerability increases due to easy communication of credentials
Solution Approach 1:
The patent introduces a physical token as an intermediary between the user and the authentication system. The token contains authentication data that must be physically presented and read by the device, creating a secure intermediary that prevents direct communication of credentials.
Solution Approach 2:
The system substitutes information-based authentication with physical object-based authentication. Instead of relying on easily communicable digital credentials, the system uses a physical token that must be physically presented, read optically or electromagnetically, and verified by the device.
Data Source
AI summary
A method and apparatus for accessing a document-processing device is provided. A request to access the document-processing device is received by the document-processing device. For example, the request may be a request to configure the document-processing device or a request to produce an electronic copy of a document. The document-processing device reads authentication data from an authentication token, which is a portable physical object associated with the user that issued the request. For example, the authentication token may be a proximity card, a common access card (CAC), a smart card, a credit card, a driver's license, or a cell phone. The document-processing device determines, based on the authentication data, whether the user has sufficient user access privileges to perform the request. If user has sufficient user access privileges to perform of the request, then the document-processing device performs the request.
