Dynamic 2D Code Groups for Tamper-Resistant Display

The patent applies dynamics by making the two-dimensional codes change over time through animation. Each code has a different animation pattern, and the codes are displayed in a specific sequence. This temporal dimension allows the reading device to distinguish between correct and incorrect codes by detecting which code is currently active in the animation sequence, thereby maintaining high reading accuracy even when multiple codes are displayed simultaneously.

The patent utilizes periodic action through the cyclic animation of two-dimensional codes. The codes are animated in a repeating sequence, and the correct code can be identified by its position in the animation cycle. The reading device detects the animation state to determine which code should be read, enabling accurate reading among multiple displayed codes through temporal periodicity.

The patent transforms static two-dimensional codes into dynamic animated codes. Each code contains animation data that causes it to change over time through playback of animation images. This dynamic characteristic prevents copying and forgery because the animated sequence cannot be easily replicated, while still using standard two-dimensional code structures that are easy to generate and distribute electronically.

The patent addresses the copying vulnerability by making the codes non-static. While the code structure itself can be copied, the animated sequence and timing information create a unique temporal pattern that cannot be perfectly replicated. The reading device verifies authenticity by checking the animation playback characteristics, thus preventing forgery while maintaining ease of electronic distribution.

The patent adds a temporal dimension to two-dimensional codes by incorporating animation sequences. Instead of moving to three-dimensional physical codes, the invention uses time as the additional dimension, creating dynamic two-dimensional codes that play back animation sequences. This approach provides enhanced security through temporal variation while avoiding the manufacturing complexity of actual three-dimensional code structures.

The patent replaces the mechanical three-dimensional code structure with a digital animation system. Instead of physically constructing three-dimensional code forms that require special production equipment, the invention uses software-generated animation sequences that can be distributed electronically. This substitution maintains security enhancements while eliminating the need for complex manufacturing processes.
