ID Document Image Knockout for Security Layer Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite advances in security features, counterfeiting and photo-swapping remain significant threats to identification documents, particularly due to the cost-effectiveness of incorporating sophisticated security methods on certain classes of documents.
Innovation Solution
A security feature for identification documents is introduced, which includes a document substrate with a first security feature and an image of the bearer having a knockout portion where selected areas are not printed, exposing the security feature and personal information, enhancing authentication and deterrence of counterfeiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated security methods are incorporated into identification documents, then security against counterfeiting and photo-swapping is improved, but manufacturing cost increases
Solution Approach 1:
The patent embeds a first security feature within the document substrate and a second security feature within a laminate layer, creating nested security elements. The knockout portion in the photographic image exposes the first security feature, while the second security feature remains visible through the transparent laminate. This nesting approach provides multiple layers of security without requiring completely separate security systems, thereby improving security while controlling manufacturing costs.
Solution Approach 2:
The patent adds a dimensional aspect to security features by creating a knockout portion that removes material or image in specific areas, exposing the underlying first security feature. This dimensional change from a flat image to a multi-layer structure with exposed elements provides enhanced security verification without requiring complex three-dimensional objects, balancing security improvement with manufacturing feasibility.
2Adaptability or versatility
If a photographic image is printed over security features, then personalization is improved, but the underlying security features become obscured
Solution Approach 1:
The patent extracts or removes the photographic image in specific areas to create a knockout portion that exposes the first security feature underlying the image. This extraction allows the security feature to remain visible while the rest of the photographic image provides personalization, effectively separating the security verification function from the personalization function in different areas of the document.
Solution Approach 2:
The patent applies different properties to different areas of the document: the photographic image is present in most areas for personalization, but a knockout portion is created in specific local areas to expose the security feature. This local differentiation allows both personalization and security visibility to coexist, with each area serving its primary function without compromising the other.
3Reliability
If a knockout portion is created to expose security features, then security verification is improved, but the image completeness is reduced
Solution Approach 1:
The patent applies partial action by creating a knockout portion that exposes only the specific area containing the first security feature, rather than removing the entire photographic image. This partial exposure provides sufficient security verification while maintaining the completeness of the rest of the photographic image for identification purposes, balancing security needs with image integrity.
Data Source
AI summary
A security feature for an identification document comprising a document substrate, a first security feature applied to the document substrate, and an image of a bearer of the identification document transferred over the first security feature. The image includes a knockout portion in which selected areas of the image are not transferred to the substrate. The selected areas expose the first security feature and selected areas are in the form of personal information of the bearer of the document.
