Abstract: In recent years, the underground market of counterfeit products has grown into a global network, causing the raised concern of the general public and initiating a series of reforms in governmental regulations and policies worldwide. As the largest independent metal decorating business in the UK, Tinmasters is at the centre of these developments. The overall aim of this project was the development of a novel anti-counterfeiting technology that is compatible with Tinmasters’ manufacturing process, food contact/safe, and preferably overt, with a special focus on aesthetic appeal. A review of pre-existing technologies revealed a trend toward systems relying on the fast-growing capacity of wireless internet and smartphone devices. The latest anti-counterfeiting systems are track-and-trace enabled and offer user-based product authentication. The review narrowed the scope of the project to the development of a scheme for the creation of printable 2D codes,capable to store information that can be retrieved using a smartphone device. The core element of the feature is a trajectory of a 3D nonlinear dynamical system operating within its chaotic region, which is captured by the system’s “strange” attractor. These types of trajectories are known for their high complexity and thought, by many, to possess beauty. More importantly, they can be retrieved via a mechanism known as chaotic synchronisation. In order to create a printable code, a 3D chaotic trajectory is projected to two dimensions. The printed feature is captured by a smartphone camera and is subsequently processed in order to retrieve the trajectory. An almost equally important element of the feature is a frame, especially designed to address matters of alignment, perspective correction, and coordinate transformations. Aside form the main field of nonlinear dynamics, the proposed scheme makes use of concepts and methods from the fields of image processing, digital photography, and numerical analysis.
