Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current document management systems lack secure and efficient methods for tokenizing physical documents, allowing for fraudulent use if both digital and physical forms coexist, and require central conversion facilities for tokenization.
Innovation Solution
A system that uses a mobile device with an image capture capability to generate unique tokens for physical documents through cryptographic functions based on their unique features, verifying destruction before releasing the token, allowing secure, one-way tokenization and eliminating the need for central conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If document management systems store both digital and physical forms of documents, then document accessibility and management efficiency are improved, but security risks increase due to potential fraudulent use
Solution Approach 1:
The patent extracts the essential identifying features from the physical document and uses them to generate a digital token, separating the security function from the physical document itself. This allows the system to manage documents efficiently in digital form while maintaining security by requiring physical document verification for token generation.
Solution Approach 2:
The patent introduces a cryptographic token as an intermediary between physical and digital document forms. The token serves as a secure bridge that links the physical document to its digital representation without allowing direct conversion, thereby maintaining security while enabling efficient digital management.
2Reliability
If centralized conversion facilities are used for tokenization, then security control is improved, but device complexity and operational overhead increase
Solution Approach 1:
The patent makes the mobile device perform multiple functions: it captures images of the physical document, processes the images to extract features, generates cryptographic tokens, and manages the tokenization process. This eliminates the need for specialized centralized conversion facilities while maintaining security control.
Solution Approach 2:
The system enables users to perform tokenization themselves using their mobile devices. The mobile device automatically captures document images, extracts features, and generates tokens without requiring centralized processing, thereby reducing device complexity and operational overhead while maintaining security.
3Ease of operation
If image-based tokenization is performed using mobile devices, then ease of operation is improved, but measurement precision of document features may deteriorate
Solution Approach 1:
The patent replaces traditional mechanical scanning systems with mobile device camera-based image capture. The system uses software-based image processing and feature extraction algorithms to compensate for the lower precision of mobile camera imaging, enabling easy operation while maintaining sufficient measurement precision for tokenization purposes.
