Watermarked Image Content for Secure Identity Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image content, such as photographs, lack interactivity, provide limited information, and pose challenges in identity authentication and privacy control, especially when used in identification cards.
Innovation Solution
Implementing watermarks that encode supplemental information, which can be retrieved using a device to access augmented content, including 3D views, higher resolution images, and interactive features, while ensuring secure access through authentication and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional photographs are used as identification, then identification function is provided, but accuracy and security of identity authentication deteriorates due to limited information and susceptibility to appearance changes
Solution Approach 1:
The patent embeds a watermark containing authentication data, cryptographic keys, and supplemental information within the conventional photograph. This nested structure allows the photo to serve both as a visual identification and as a carrier of secure authentication data, resolving the contradiction by preserving the original photo's information while adding layered security information.
Solution Approach 2:
The watermark acts as an intermediary layer between the conventional photograph and the authentication system. It carries cryptographic keys and authentication data that mediate the verification process, enabling accurate identity authentication without relying solely on the limited visual information in the photograph.
2Ease of operation
If conventional photographs allow free access to all information, then ease of viewing is improved, but privacy control and distribution security deteriorates
Solution Approach 1:
The patent applies different access rights to different parts of the photograph information. The watermark contains cryptographic keys that enable selective decryption and access control, allowing certain portions of the supplemental information to be accessible while other sensitive portions remain protected, thus resolving the contradiction between ease of access and privacy control.
Solution Approach 2:
The patent implements dynamic access control where the level of information access changes based on authentication credentials. Users can interact with the photograph at different levels - from basic viewing to detailed inspection - with each level requiring appropriate authentication, thereby enabling both ease of operation and privacy control.
3Adaptability or versatility
If conventional photographs are static images, then simplicity is maintained, but interactivity and user engagement deteriorates
Solution Approach 1:
The patent embeds the watermark and authentication data in advance within the conventional photograph during its creation or distribution. This preliminary action prepares the photograph to support interactive features without requiring complex real-time processing, thus enabling adaptability while maintaining relative simplicity.
Solution Approach 2:
The patent uses the conventional photograph as a base copy and overlays it with a watermark containing additional information and authentication data. This copying approach allows the original simple photograph to be enhanced with interactive capabilities while maintaining the simplicity of the base image structure.
4Loss of information
If multiple photographs are used to provide detailed information, then information completeness is improved, but ease of viewing and understanding deteriorates due to sequencing and context requirements
Solution Approach 1:
The patent merges multiple pieces of information - the conventional photograph, supplemental detailed information, and authentication data - into a single watermarked image. This combining allows all information to be accessed from one location rather than requiring users to sequence multiple photographs, thus improving both information completeness and viewing convenience.
Solution Approach 2:
The patent adds an information dimension to the conventional photograph by embedding a watermark that contains supplemental information. This transforms the two-dimensional photograph into a multi-layered information structure where additional details and perspectives are accessible within the same visual space, eliminating the need to view multiple separate photographs.
