Dynamic Twinkling Data Encoding for Screen Noise Immunity

The patent changes the display parameters by using dynamic twinkling patterns at specific frequencies (e.g., 5Hz-50Hz) instead of static displays. This temporal modulation allows the image capturing device to distinguish the data pattern from screen noise through frequency filtering, thereby maintaining high capturing accuracy while preserving the convenience of screen-based data exchange.

The patent implements periodic action by displaying data patterns that twinkle or flash at regular intervals with predetermined frequencies. This periodic display creates a temporal signature that can be detected and filtered by the reading apparatus, enabling accurate data extraction even in the presence of screen noise and varying display specifications.

The patent employs parameter changes by encoding data through temporal frequency patterns rather than relying on fixed spatial patterns. This approach makes the data representation independent of specific screen resolutions, colors, or refresh rates, allowing the reading apparatus to adapt to various display specifications while maintaining high reading success rates through frequency-based detection.

The patent achieves universality by creating a data display method that works across different portable electronic apparatus screens with varying specifications. The frequency-based twinkling pattern serves as a universal language that can be detected by the reading apparatus regardless of the display hardware differences, thereby improving both adaptability and reading reliability simultaneously.

The patent introduces periodic action through dynamic twinkling patterns that change over time. This temporal variation adds a layer of security by making the data pattern time-dependent, thereby preventing static capture and replay attacks. The periodic nature of the display allows for easy detection and decoding while maintaining relative simplicity in the display mechanism.

The patent applies dynamics by transitioning from static data patterns to dynamic twinkling patterns. This dynamic display approach enhances data security by preventing straightforward copying or replay of the data, while the underlying pattern recognition algorithm remains relatively simple, thus balancing security improvement with acceptable system complexity.
