IR Mark Embedding in Document Blank Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for embedding Infrared (IR) marks in documents often result in content loss, such as cropping or overwriting important information like logos, titles, and author details, due to the placement of IR marks in corners where important content is present.
Innovation Solution
A method and system that identify blank spaces in documents before embedding IR marks, allowing users to select an option to check for content loss, extract the relevant document portion, calculate white pixels to determine blank space availability, and embed the IR mark only in sufficient spaces, minimizing content loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IR mark is printed in the corner of the document, then security authentication is enhanced, but existing content in that corner gets overwritten causing content loss
Solution Approach 1:
The system performs preliminary detection of blank spaces in document corners before embedding the IR mark. By analyzing the document content in advance and identifying suitable blank areas, the system ensures that the IR mark is placed only in locations that will not overwrite important content, thus preventing content loss while maintaining security authentication.
Solution Approach 2:
The system applies different treatment to different corners of the document by individually analyzing each corner for blank spaces. Instead of uniformly placing IR marks in all corners, the system selectively embeds IR marks only in corners that have sufficient blank space, allowing important content in other corners to be preserved.
2Ease of operation
If IR mark is embedded in desired corner, then user's positioning requirement is met, but important content like logo, titles, date, author information gets cropped
Solution Approach 1:
The system provides feedback to the user by detecting and analyzing the content in the desired corner before finalizing the IR mark placement. If important content is detected in the specified corner, the system can notify the user and suggest alternative locations, allowing the user to make an informed decision while preventing unintended content loss.
Solution Approach 2:
The system performs preliminary content analysis in the user-specified corner before embedding the IR mark. By checking for the presence of important content elements such as logos, titles, dates, and author information in advance, the system can prevent cropping of these elements while still respecting the user's positioning preferences.
3Loss of information
If content check option is provided to user, then content loss is minimized, but processing time and complexity increase
Solution Approach 1:
The system provides an automated content detection and analysis feature that works independently once enabled. The content check option automatically analyzes document corners for blank spaces and important content elements without requiring manual user intervention, reducing the perceived complexity for users while maintaining high content preservation capabilities.
Solution Approach 2:
The content check functionality performs preliminary automated analysis of document corners before IR mark embedding. By automatically detecting blank spaces and important content elements in advance, the system minimizes content loss without requiring complex manual processing, thus reducing the effective processing complexity for users.
Data Source
AI summary
The present disclosure discloses methods and systems for identifying blank spaces in a document for embedding an Infrared (IR) mark in the document. The method includes receiving the document for printing from the user. A user interface is provided to the user that allows the user to select a pre-defined option. Upon selection of the pre-defined option, inputs from the user on the IR mark is received. Based on the inputs from the user, a specified portion of the document is extracted for processing. Then, blank spaces are checked in the extracted portion based on a size of the IR mark to be embedded in the document. Based on the check, the IR mark is embedded in the identified blank space. An output document is outputted/printed including the IR mark in the specified portion of the document. The IR mark is embedded such that there is no content loss.
