Image Processing Device Authentication via Scanned Identifying Image
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 an identifying image from a scannable area on a sheet, an image obtainer to process the image, a judging unit to verify the image against a predetermined authentication criterion, and a function controller to activate device functions based on the authentication, allowing users to access functions without manual input of credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of identifying information is required, then authentication can be performed, but the operation becomes cumbersome and error-prone
Solution Approach 1:
The patent replaces the mechanical keyboard input system with an optical scanning system. The scanner reads identifying information from images (barcodes, QR codes, or handwritten text) on documents, converting optical information into digital data for authentication. This eliminates the need for manual keyboard entry while maintaining authentication reliability.
Solution Approach 2:
The patent introduces an intermediary document with printed or handwritten identifying information that serves as a mediator between the user and the authentication system. Instead of direct keyboard input, the user places the document on the scanner, and the system extracts identifying information from the image, reducing direct manual interaction.
2Loss of information
If manual input is used, then user identification can be obtained, but time is lost due to redundant input operations
Solution Approach 1:
The identifying information is pre-prepared on documents in the form of barcodes, QR codes, or handwritten text. Users can prepare multiple such documents in advance, and during authentication, they simply need to place the appropriate document on the scanner, eliminating the need for real-time manual input and significantly reducing authentication time.
Solution Approach 2:
The patent uses optical copies (scanned images) of identifying information from physical documents instead of requiring direct manual entry. The scanner creates a digital copy of the identifying information from the document image, which is then processed for authentication, greatly accelerating the information acquisition process.
3Device complexity
If the input device has few keys, then device simplicity is maintained, but input complexity increases
Solution Approach 1:
The patent replaces the mechanical keyboard with an optical scanning system that reads identifying information from images. This substitution eliminates the need for multiple keys while maintaining or improving operational ease, as users simply need to place a document with the identifying information on the scanner rather than manually typing.
Solution Approach 2:
The patent transitions from one-dimensional keyboard input (pressing keys sequentially) to two-dimensional image scanning (reading information from a document surface). This dimensional change allows the system to capture and process identifying information without requiring multiple keys, resolving the contradiction between device simplicity and operational ease.

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