Abstract
The present technology provides dynamic security code systems and method for their creation and use. The systems include a base layer including a first pattern and a sublimating compound layer including a plurality of materials selectively covering the base layer. In some embodiments, each of the plurality of materials is configured to sublimate at respective sublimation rates. The system further includes a shielding layer configured to shield the base layer and the sublimating compound layer to form a security code. The shielding layer can be configured to control a diffusion rate of the plurality of materials through the shielding layer such that the security code is changed.
