System uwierzytelniania optycznego DotAuth

autorzy: Kamil Kaczyński, Michał Glet

DotAuth is a system that allows authentication of printed documents and other physical elements with a flat structure. The system uses the image recognition process in modern smartphones, as a result of which the microcode authenticating the marked document / object placed in the image is recognized. The microcode is applied in a form that does not require the use of synchronization mechanisms - it can be read in any orientation, while not reducing the readability of the marked document. The entered microcode is in the form of microdots arranged in a way that allows reproducing the geometric structure in which it is entered, which translates into reproducing the value of the authentication code. The code is distributed in many parts of the document, which increases its resistance to removal. Security and anti-counterfeit mechanisms of DotAuth are based mainly on most secure cryptographic and steganographic algoriths.
