Printing System Confidentiality via User Thumbnail Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared printing systems, maintaining confidentiality of print jobs is challenging due to the exposure of thumbnail images representing print jobs, making it difficult for users to identify their requested jobs among multiple stored print jobs, and risking the confidentiality of sensitive content.
Innovation Solution
A printing apparatus and system that uses user-specific thumbnail images, associated with security information, to differentiate and protect confidential print jobs, ensuring only authorized users can view and access their respective print data by displaying user-specific thumbnail images when security information is entered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thumbnail images representing print job contents are displayed to help users identify their jobs, then ease of operation is improved, but confidentiality of print jobs is compromised
Solution Approach 1:
The patent introduces a thumbnail image management system that acts as an intermediary between the print job content and the user. Instead of displaying actual print content, the system generates and displays thumbnail images that represent the print jobs. Users can identify their print jobs through these thumbnails without exposing sensitive content, thus resolving the contradiction between ease of identification and confidentiality protection.
2Loss of information
If solid black images are used to represent confidential print jobs, then confidentiality is maintained, but ease of identifying the requested print job deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of thumbnail images based on their associated print jobs. Confidential print jobs are represented by solid black thumbnails, while non-confidential jobs display normal thumbnails. This localized differentiation allows users to easily identify their print jobs among mixed types without compromising the confidentiality of sensitive documents.
3Productivity
If multiple print jobs are stored in HDD for secure printing mode, then productivity is improved, but difficulty of searching for the correct print job increases
Solution Approach 1:
The patent creates thumbnail image copies of print jobs stored in the HDD. These thumbnail copies serve as visual indexes that allow users to quickly search and identify their print jobs without having to manually review the actual print content. This copying mechanism significantly reduces the time and effort required to locate specific print jobs among multiple stored files.
Data Source
AI summary
A printing apparatus to process a print job is provided. The printing apparatus includes a printing unit to form an image according to print data, a displaying device to display information concerning an operation of the printing apparatus, a first storage unit to store first user information, which identifies a user of an information processing apparatus, in association with a user-specific thumbnail image, which is to be displayed in the displaying device to identify the print job provided by the user, a first judging unit to determine as to whether the print job includes first security information, which is specified by the user to prevent contents of the print data from being disclosed, and the first user information, and a first display control unit to display the user-specific thumbnail image when the first judging unit determines that the print job includes the first security information and the first user information.
