Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identification cards display detailed identity information without control, raising privacy concerns in the era of information explosion.
Innovation Solution
An electronic identification card with an e-paper display, security chip, and processing circuit that allows for authentication and editing of displayed identity information, using augmented reality to selectively display barcodes representing chosen items, thereby controlling the level of detail shown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional identification cards display detailed identity information directly, then the information is easily accessible, but privacy protection deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (processing circuit with authentication function and barcode generation) between the identity information storage and the display. The security chip stores detailed identity information, while the e-paper display shows only authenticated barcodes. This intermediary layer filters and controls information flow, allowing selective disclosure while protecting privacy.
Solution Approach 2:
The patent segments identity information into two layers: detailed information stored in the security chip and simplified barcode representations displayed on the e-paper. This segmentation allows the system to maintain comprehensive information availability while displaying only necessary minimal information, reducing privacy exposure.
2Loss of information
If the e-paper display shows all identity information, then completeness is maintained, but privacy protection deteriorates
Solution Approach 1:
The system implements partial action by displaying only the necessary minimal information (barcodes) rather than all detailed identity information. The security chip retains complete information, but the e-paper display performs selective disclosure based on authentication results, showing only what is needed for the specific operation.
Solution Approach 2:
The display content is dynamic rather than static. The e-paper display shows different barcode representations based on authentication status and user requests. The system can adaptively disclose different levels of information depending on the authentication result, transforming the display from fixed to flexible and controllable.
3Object-affected harmful factors
If authentication mechanism is added to control information display, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components: the processing circuit combines authentication logic, barcode generation, and display control in one unit. The security chip integrates information storage with authentication verification. This merging reduces the number of separate components and simplifies the overall system architecture while maintaining strong privacy protection.
Solution Approach 2:
The authentication mechanism operates autonomously within the card system. The processing circuit automatically verifies authentication credentials and controls display content without requiring external intervention. The security chip self-verifies authentication status and determines what information to make available, reducing the need for complex external control systems.

AI summary
An electronic identification card is provided and includes an e-paper display, a security chip, and a processing circuit. The processing circuit receives a modification request from an electronic device and performs an authentication process. If the authentication process is passed, the security chip transmits identity information to the electronic device in which the identity information contains multiple items. The processing circuit also receives edited information from the electronic device, based on which it decides at least one item to be displayed among the aforementioned items, generates a barcode according to the item to be displayed, and controls the e-paper display to show the barcode.
