Dynamic-Background QR Codes for Screenshot Authenticity

The patent applies dynamics by replacing static background images with real-time camera capture images that continuously change. The camera captures the surrounding environment in real-time and displays it as the background behind the two-dimensional code, making the code dynamic and time-dependent. This resolves the contradiction by enhancing security through dynamic content while maintaining relatively simple code generation logic.

The patent changes the parameter of background image from static to dynamic by introducing real-time camera capture. The background image parameter is transformed from a fixed file to a continuously updating video stream, which enhances security without fundamentally changing the two-dimensional code structure itself.

The patent applies local quality by creating gaps only between adjacent color blocks while maintaining the integrity of individual color blocks themselves. The gaps are strategically placed in the interstices between blocks, allowing the background to show through without compromising the encoding information within each block. This resolves the contradiction by providing security through selective transparency while preserving code readability.

The patent segments the two-dimensional code structure by introducing gaps between color blocks, effectively dividing the continuous code pattern into separated elements. This segmentation allows the background to be visible through the gaps while maintaining the overall code structure, balancing security requirements with code integrity.
