Brand Protection with 3 Dimensional Code
Brand protection with 3Dcode (3 dimensional physically unclonable function) was born by a brand owner, who was suffering from copying. He engaged computer architects and engineers, who then realized the nature of the broad issue. The engineering group researched a number of methods to solve the issue which perfectly protects brands. They came up with an idea of using a method, a physically unclonable function. You can find the definition of 3D PUF in Wikipedia as follows:
A physical unclonable function (sometimes also called physically unclonable function, which refers to a weaker security metric than a physical unclonable function), or PUF, is a physical object that for a given input and conditions (challenge), provides a physically-defined “digital fingerprint” output (response) that serves as a unique identifier, most often for a semiconductor device such as a microprocessor. PUFs are most often based on unique physical variations that occur naturally during semiconductor manufacturing. A PUF is a physical entity embodied in a physical structure. Today, PUFs are usually implemented in integrated circuits and are typically used in applications with high-security requirements, more specifically cryptography.
3D PUF code uses multiple physical layers with fine particles sprayed over the top layer.
Those particles are different in size and height making unique value, which one cannot duplicate the same one. This makes it fundamentally impossible to copy the code. So that once merchandise, plastic card, or document embraces the code, it offers a perfect anti-counterfeiting mechanism. Furthermore, it uses a smartphone to scan and validate the object embedded with the code.
Globally, brands lose trillion dollars and millions of jobs per annum due to fake brands. 3D PUF Code helps brands to protect their identity, which leads not only to giving consumer confidence but also to retaining revenue.
