Embodiments of this application disclose an object on which a two-dimensional code is disposed, a two-dimensional code generation method, identification method, generation apparatus, and identification apparatus, and a storage medium. The two-dimensional code includes a square module array of m*m modules. The square module array includes a location detection pattern and a data information pattern. The location detection pattern is used for determining a location of the two-dimensional code. The data information pattern is used for carrying data. m=17 or 18 or 19 or 20. Even if printed in a miniature area whose side length is 0.5 cm to 0.7 cm, a miniature two-dimensional code provided in the embodiments of this application can still be normally identified, and is suitable for being used in a small area application scenario such as an inner side of a bottle cap or a corner of an object.

Techniques to improve detection and security of images, including formation and detection of matrix-based images. Some techniques include logic to process image data, generate one or more colorspaces associated with that data, and perform colorspace conversions based on the generated colorspace. The logic may be further configured to generate an image based on the colorspace conversions, including but not limited to a matrix bar code. The logic may be further configured to apply one or both of an ultraviolet layer and an infrared layer to the image, e.g. matrix barcode, generated from the colorspace conversion(s). Other embodiments are described and claimed.

Techniques to improve detection and security of images, including formation and detection of matrix-based images. Some techniques include detecting a matrix-based image that is optimized for detection in a particular environment. The matrix-based image may be a matrix bar code. The matrix bar code may include a plurality of non-black and non-white colors, where each one of the plurality of non-black and non-white colors are at least one of an absent color in relation to the environment and a least prevalent color associated with the environment.

Disclosed is a method of generating a code including additional information, including: generating, by an administrator module interworking with a product selling server, a first code including information about a product to be sold by a seller; generating, by the administrator module, a second code including information about a store where the product to be sold by the seller is located and distinguished from the first code; and generating, by the administrator module, a completion code including the product information and the store information of the corresponding product by combining a plurality of codes including the first and second codes, wherein the completion code is configured to have information different from the first and second codes by combining information about a same point of the first and second codes.

An optical code is readable by a generally used reading device, and optically readable as an information code that can appropriately prevent abuse due to duplication. In this optical code, data is recorded with a pattern of a plurality of light-color modules having high visible light reflectance and a plurality of dark-color modules having visible light reflectance lower than light-color modules. At least either the light-color modules or the dark-color modules are configured to include a first module and a second module having reflectances different from each other for invisible light of a predetermined wavelength. Thus, data is recorded as a readable pattern of modules, the pattern being differently observed between when irradiated with visible light and when irradiated with the invisible light of a predetermined length.

The present invention relates to systems, entities, and methods for certificates and certifications of documents, such as passports, licenses, degree certificates, and the like. More specifically, the present invention relates to re-certifying a document in the sense of verifying and/or renewing an already existing certificate/certification.
