Image Processing Device User Authentication via Optical Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing devices require users to manually input identifying information, which can be cumbersome and prone to errors, especially when using devices with a small number of keys.
Innovation Solution
An image processing device that includes a scanner to read images from a sheet, a judging unit to authenticate users based on a predetermined identifying image, and a function controller to activate device functions when the authenticating image matches the stored identifying image, eliminating the need for manual input of user credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual input device with small number of keys is used for authentication, then device complexity is reduced, but ease of operation deteriorates and input errors increase
Solution Approach 1:
The patent replaces the mechanical key input system with an optical recognition system. The imaging device captures images of the user's hand holding a finger-print card or similar identifying object, and the image processing unit automatically recognizes and extracts identifying information from the captured image, eliminating the need for manual key input while maintaining simple device structure.
Solution Approach 2:
The system enables self-service authentication by allowing users to present their own identifying objects (such as finger-print cards) which are automatically recognized by the imaging device. The identifying information is extracted automatically without requiring user manipulation of input keys, making the authentication process self-serving and convenient.
2Device complexity
If manual input device with small number of keys is used for authentication, then device complexity is reduced, but reliability deteriorates due to input errors
Solution Approach 1:
The patent replaces the mechanical key input system with an optical recognition system. The imaging device captures images of the user's hand holding a finger-print card or similar identifying object, and the image processing unit automatically recognizes and extracts identifying information from the captured image, eliminating the need for manual key input while maintaining simple device structure.
Solution Approach 2:
The system provides visual feedback by displaying the captured image and the extracted identifying information on a display unit. This allows users to verify that their identifying object was correctly recognized, and provides an opportunity to correct any recognition errors before final authentication, thereby improving reliability.
3Ease of operation
If automatic image-based authentication is implemented, then ease of operation is improved and input errors are reduced, but device complexity increases
Solution Approach 1:
The imaging device, which is already a core component of the system for its primary function, is utilized for the additional authentication function. The same imaging device captures both the document to be processed and the user's identifying object, eliminating the need for separate authentication hardware and reducing overall device complexity.
Solution Approach 2:
The patent merges the authentication function with the existing document processing workflow. The imaging device captures images serving dual purposes: the document image for processing and the identifying image for authentication. The image processing unit handles both types of images, combining multiple functions into existing components rather than adding separate systems.

AI summary
An image processing device is provided. The image processing device includes a scanner to scan an image formed on a sheet, a first image obtainer to read and obtain a first image being a processible image formed in a first area, the first area being allocated on the sheet, a second image obtainer to read and obtain a second image formed in a second area, the second area being allocated on the sheet separately from the first area, a judging unit to judge as to whether the second image obtained by the second image obtainer is qualifies a predetermined authentication criteria and is identical to a predetermined identifying image, and a function controller to activate a predetermined function of the image processing device, which processes the processible image obtained by the first image obtainer, when the judging unit judges that the second image is identical to the predetermined identifying image.
