Abstract

A system associated with authentication of an object related to a multi-mode marker using a processing device. The processing device performs operations that include detecting a signal associated with a multi-mode marker related with the object; assigning a digital code based on the detected signal associated with the multi-mode marker; and identifying the object based on the digital code related to authentication of the object. A corresponding method and computer-readable device are also disclosed.
