The present invention is an imprint device for imprinting a unique identification mark on a surface of an object with imprinting particles of different sizes that increase uniqueness and without the need for electric power. The imprint device includes a vertical member, a hammer member, a trigger assembly, a charging unit, a barrel and at least one pocket. In the operative configuration, a trigger of trigger assembly is activated such that hammer member impacts a cartridge filled with at least one munition of imprinting particles and releases imprinting particles. The imprinting particles travel through the barrel where acceleration is increased and impact on surface is made to form microcraters and unique identification marks. The imprinting particles can be of same size, material and shape or they can be of different sizes, material and shapes or the combination thereof for increasing uniqueness.

Disclosed herein is an authenticating mark formed on the surface of a product or package. The said mark comprising: at least an overt portion of visible 3D random image in the form of physically unclonable function (PUF) characterized in that the said PUF is random cracks or colors. Additionally, phosphor particles might be added to this pattern as covert features. It further disclose a system and method for identifying genuine or counterfeited products by analyzing the image of a 3D-PUF and its encrypted image using a commonly held scanning device.

An anti-counterfeiting tag, system and method of manufacturing and authentication therefor are provided. The tag comprises a substrate; and a plurality of layers printed on at least a portion of the substrate; wherein one of said plurality of layers is configured to generate a self-forming three dimensional (3D) raised random pattern comprising physically unclonable function (PUF) and the other layers are configured to facilitate formation of the 3D pattern and/or to protect the formed 3D pattern.

An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.

A plasmonic pixel structure, comprising: a substrate; a plurality of nano-scale structures each comprising conducting and dielectric components, whereby the nano-scale structures are configured to act as nano-antennas. The nano-scale structures 5 have resonant frequencies that depend on the conducting component and sizes of the nano-scale structures. The conducting component and the sizes of the nano-scale structures are selected according to a wavelength component or components of incident light desired to be reflected or transmitted by the nano-scale structures, and the conducting component and the sizes of the nano-scale structures are selected 10 such that the nano-scale structures have respective resonant frequencies corresponding to a colour scheme.

A method for creating a nanostructure surface, comprises creating a nanostructure master having a surface being the negative of a shape that, when illuminated with a predefined illumination, provides a unique optical pattern; and creating nanostructure molds from the nanostructure master, wherein each nanostructure mold has a negative of the master surface which, when illuminated with the predefined illumination, provides the unique optical pattern, which may be a hologram. A nanotag may incorporate an image for identification and a unique pattern that can be identified for authentication.

An ammunition tracking system. The ammunition tracking system comprises a server having a data storage. The server is configured to receive data corresponding to a symbolic encoded identifier marked on ammunition, receive data corresponding to a purchaser of the ammunition, associate the data corresponding to the symbolic encoded identifier with the data corresponding to the purchaser of the ammunition, receive data corresponding to a retrieved ammunition casing, and compare the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition. Upon matching the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition, the server is configured to transmit the data corresponding to the purchaser of the ammunition.
