Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QR codes with password protection are used for electronic tickets, then security protection is provided, but user convenience deteriorates due to manual password entry and verification
Solution Approach 1:
The patent merges the verification data with the image stream by embedding timing data sequences directly into pixel modifications of the image. This combination eliminates the need for separate password entry fields or manual verification steps, as the verification data is seamlessly integrated into the visual display itself, allowing automatic verification when the image is captured.
Solution Approach 2:
The system enables self-service verification by encoding verification data directly into the image stream that users already possess on their devices. When captured by the POS system, the image automatically contains all necessary verification information, eliminating the need for users to manually enter passwords or provide additional authentication, thus serving themselves without external intervention.
2Reliability
If manual verification of electronic tickets is performed, then verification can be conducted, but labor costs and verification time increase significantly
Solution Approach 1:
The patent replaces the manual mechanical verification process with an automated optical system. Instead of employees manually reading and verifying ticket information, the system uses image capture devices to automatically detect and decode the embedded verification data within the image stream, substituting human labor with automated machine processing.
Solution Approach 2:
The verification data is prepared and embedded into the image stream in advance before the verification moment. The timing data sequence is pre-calculated and integrated into the image pixels, so that when the image is captured, verification can immediately proceed without requiring real-time computation or manual data preparation, thus improving verification speed.
3Ease of manufacture
If traditional electronic ticket systems are used, then ticket issuance is simple, but verification accuracy deteriorates due to manual data entry errors
Solution Approach 1:
The patent creates an optical copy of the verification data embedded within the image stream itself. Instead of relying on separate digital databases or manual transcription, the verification information is encoded directly into the visual representation, allowing the POS system to read and verify data directly from the image capture, eliminating transcription errors while maintaining the simplicity of digital ticket distribution.

AI summary
A method and device of generating an image stream with verification data are provided. The method includes the following steps. First, determine at least one pixel in a first image according to a first encoding parameter. Then, generate a timing data sequence associated with information about the correlation between the verification data and time points according to a second encoding parameter and the verification data. Next, modify a pixel value of the at least one pixel in the first image to generate a second image according to the verification data corresponding to one of the time points in the timing data sequence. Lastly, generate the image stream including the second image.
