Masked Document Image Processing With QR Inquiry Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users who do not have restricted access to the concealed portions of a printed document cannot check the masked content, necessitating additional processing to obtain the original unmasked data.
Innovation Solution
An image processing apparatus performs masking on concealed portions based on access policies and embeds inquiry information for checking the masked content, using a two-dimensional code to facilitate access policy verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If masking processing is performed on concealed portions to prevent information leakage, then security is improved, but users without restricted access cannot check the concealed portion
Solution Approach 1:
The patent introduces inquiry information (QR codes, barcodes, or URLs) as an intermediary element that mediates between the masked printed matter and the original data source. This intermediary allows users to access and verify the concealed portion content without directly exposing the sensitive information in the printed output, thus maintaining security while enabling verification capability.
Solution Approach 2:
The patent transitions the verification capability from the two-dimensional printed space to a digital/different dimensional space by embedding inquiry information that links to electronic storage or display systems. Users can access the original content through this dimensional transition via smartphones or computers, allowing verification without compromising the printed document's security.
2Reliability
If masking processing is applied to concealed portions, then information leakage is prevented, but additional processing is required to obtain original unmasked data
Solution Approach 1:
The patent performs preliminary action by pre-embedding inquiry information (QR codes, barcodes, or URLs) into the masked printed matter during the printing process. This preliminary inclusion of access pathways eliminates the need for users to perform time-consuming manual procedures to obtain original data, as the verification mechanism is already prepared and integrated into the printed output.
Solution Approach 2:
The patent implements a feedback mechanism where inquiry information provides direct access to the original unmasked data through digital channels. Users can instantly retrieve and verify the concealed portion content by scanning or accessing the embedded inquiry information, creating a rapid feedback loop that eliminates delays associated with traditional manual verification processes.
3Reliability
If masking processing is performed on concealed portions, then access control is enforced, but users cannot verify the concealed content without requesting original data from the creator
Solution Approach 1:
The patent introduces inquiry information as a mediator that simplifies the verification process. Instead of requiring direct contact with the data creator or complex authorization procedures, the embedded inquiry information (QR code, barcode, or URL) serves as a self-contained intermediary that provides users with immediate access to verify concealed content through straightforward scanning or web access.
Data Source
AI summary
An image processing apparatus includes a processor configured to: in a case of printing data to be printed, perform masking processing on a predetermined concealed portion according to a predetermined access policy; and perform a process of embedding and outputting inquiry information for inquiring about the concealed portion in the data to which the masking processing has been performed.
