Solution Overview

Problem

Existing methods for securing confidential information on documents often allow unintended access or damage when the masking layer is removed, and lack assurance that the information has not been previously accessed.

Innovation Solution

A document security device featuring a window with structural weaknesses along its edges, a first label carrying the information positioned within the window, and a masking label that covers the entire window periphery, ensuring the information is only accessible by removing the masking label without damaging the document or revealing prior access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a masking element is used to conceal confidential information, then information security is improved, but the masking element may be removed to reveal the information, allowing unauthorized access or re-masking

Engineering Contradiction:
Improveinformation securityVSAvoidconfidentiality assurance
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The masking element is divided into two functional parts: a removable masking portion that covers the information and a fixed peripheral portion that remains attached to the document. This segmentation allows the masking to be removed for legitimate reading while the fixed perimeter provides permanent security verification

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixed peripheral portion of the masking element is pre-configured with security features (such as perforated edges or torn sections) that are damaged upon any removal attempt. This preliminary action ensures that before the information can be accessed, the security system has already recorded whether unauthorized removal occurred

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the masking element is removed to access information, then information accessibility is improved, but the document or information support element may be damaged

Engineering Contradiction:
Improveinformation accessibilityVSAvoiddocument integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The masking element is segmented into a removable central portion and a fixed peripheral portion. The removable portion is designed to be detached without applying stress to the document or information support element, while the fixed portion maintains document integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The potentially damaging masking element is extracted from the document structure by making it a separate, removable component rather than being permanently integrated. This allows the masking to be removed without compromising the underlying document or information carrier

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a masking element completely covers the information area, then information security is improved, but the masking element cannot be permanently fixed to prevent re-masking

Engineering Contradiction:
Improveinformation securityVSAvoidmasking structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The masking element is segmented into a removable masking portion and a fixed peripheral portion. This segmentation enables the fixed perimeter to provide permanent security anchoring while the removable portion maintains the confidentiality function, avoiding the need for complex multi-component systems

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixed peripheral portion of the masking element serves multiple functions simultaneously: it provides permanent attachment to the document, establishes security verification features, and defines the boundaries of the confidential information area. This multi-functionality reduces overall device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a document (1) which is provided with a device for securing confidential information mentioned in the document, the latter comprising: a window (8) cut into said document; at least two structural weakness areas (11, 12) located adjacent to two edges (81, 83) of the window (8); an information medium formed by at least one first label (16) attached to one surface (18) of the document (1) such that the confidential information printed on said label (16) is located level with the window (8); an element (3) for masking the information, with dimensions at least equal to those of the window (8), permanently secured to the structural weakness areas (11, 12) and removably mounted in the window (8). A second label (19), suitable for protecting the first label (16) and for allowing the confidential information to be read when the masking element (3) is lifted, is arranged in the window (8) of the document (1), from the surface (20) of the document (1) opposite the surface (18) which is provided with the first label (16), the dimensions of said second label (19) being smaller than those of the window (8). The masking element (3) is also located on the surface (20) of the document and furthermore has dimensions that enable the element to be permanently secured, by all the sides thereof, to the document adjacent to all the edges of the window (8), including those which lack structural weakness areas (11, 12). The invention also relates to a method for implementing such a document.
