An article of manufacture may include a matrix barcode on a physical medium and associated with an environment. The matrix barcode may include a plurality of colors, where at least one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment.

An apparatus may include a memory to store instructions; and processing circuitry, coupled with the memory, operable to execute the instructions. When executed, the instructions may cause the processing circuitry to identify a matrix code; read a first layer of the matrix code, the first layer comprising a first account identifier associated with an account, wherein the first layer corresponds to a first color channel; and read a second layer of the matrix code, the second layer comprising a set of account data, associated with the account, wherein the second layer corresponds to a second color channel, different than the first color channel.

A method of generating a semi transparent QR code in which a QR code image and an ordinary color background image are synthesized, and a QR code detection method of separating a QR code and a normal color image from an image obtained by capturing a semi transparent QR code are disclosed.

A security feature and a method for creating a barcode are disclosed. Data is concatenating to be represented in the barcode. The concatenated data is partitioned into n-bit segments. The formatted data is encoded by assigning a respective code to each n-bit segment. The barcode is created using the encoded data.

A matrix barcode on a surface may comprise a plurality of colors, an infrared layer, and an ultraviolet layer. The matrix barcode may be a fiducial marker for conveying spatial information. The spatial information may stem at least in part from the infrared layer and the ultraviolet layer.

An image processing apparatus includes an acquisition unit that acquires setting information acquired from a captured image, a setting unit that performs, based on the acquired setting information, setting regarding image analysis processing to be performed on a captured image obtained by capturing an image of a predetermined monitoring target range.

An apparatus may include a memory to store instructions; and processing circuitry, coupled with the memory, operable to execute the instructions. When executed, the instructions may cause the processing circuitry to identify a matrix code; read a first layer of the matrix code, the first layer comprising a first account identifier associated with an account, wherein the first layer corresponds to a first color channel; and read a second layer of the matrix code, the second layer comprising a set of account data, associated with the account, wherein the second layer corresponds to a second color channel, different than the first color channel.

A method and system are provided. The method involves generating a plurality of nanoparticles, isolating fluorescent nanoparticles, embedding the fluorescent nanoparticles in a resin and applying the resin on a product. The system is for product authentication and includes a light source, fluorescence nanoparticles, a detector and a resin for applying on a product.
