Smart Glass Overlay for Secure Image Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for smart glass applications lack a convenient method to integrate with image forming apparatuses, such as MFPs, to efficiently overlay supplementary information onto real-world scenes, posing challenges in information access and security.
Innovation Solution
A display system comprising an image forming apparatus, a server, and smart glass that extracts and separates image information, allowing only background images to be printed while overlaying extraction information, like text or images, onto the real-world view through the smart glass, using CCDs for image capture and processing, and controlling the display with processors and storage sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all image information is printed on paper, then complete information is provided to users, but information leakage risks and printing costs increase
Solution Approach 1:
The patent segments image information into two distinct parts: background images (printed on paper) and extraction information (displayed on smart glass). This segmentation allows selective distribution of information - sensitive extraction information remains digital and accessible only through authenticated devices, while background images provide contextual reference without revealing sensitive details
Solution Approach 2:
The patent extracts specific information elements from the complete image data and separates them into extraction information that is exclusively displayed on smart glass devices. This extraction process removes sensitive content from the physical printout, reducing information leakage risks while maintaining full information accessibility through the integrated system
2Loss of substance
If complete image information is printed, then no information needs to be viewed through smart glass, but printing costs and material consumption increase
Solution Approach 1:
The patent creates a digital copy of extraction information that is displayed on smart glass instead of being printed physically. This virtual copy replaces the need to print sensitive information, reducing paper and ink consumption while maintaining information accessibility through the smart glass interface
Solution Approach 2:
The patent implements a multi-functional system where the image forming apparatus not only prints background images but also generates and transmits extraction information to smart glass devices. This universal approach consolidates multiple functions (printing, digital display, authentication) into an integrated system, managing complexity through unified control
3Reliability
If extraction information is displayed on smart glass, then information security is improved, but device complexity and authentication requirements increase
Solution Approach 1:
The patent implements authentication mechanisms where the smart glass device automatically performs verification processes. The system handles authentication credentials, position verification, and information release automatically, reducing the manual burden on users while maintaining security requirements
Solution Approach 2:
The patent introduces the smart glass device as an intermediary between the user and the extraction information. This intermediary layer handles authentication, position-based access control, and information display, simplifying the user experience while enforcing security protocols through the intermediate device
4Reliability
If position-based access control is implemented, then information security is enhanced, but system complexity and processing requirements increase
Solution Approach 1:
The patent implements position-based access control where the smart glass device continuously monitors its position relative to the image forming apparatus and receives feedback signals. The system automatically adjusts information release based on verified position data, creating a closed-loop control system that enhances security through dynamic position verification

AI summary
In general, an image forming apparatus according to the present embodiment comprises an image forming section, a reading section and a controller. The image forming section forms an image on a sheet. The reading section reads the image on the sheet to generate scan image information. The controller generates background image information obtained by excluding extraction image information from the scan image information and forms the background image information, first identification information of the sheet and orientation information indicating orientation of the sheet on the sheet through the image forming section.
