Abstract

The invention provides a safety product and a detecting method and a detecting system thereof. The safety product is provided with a safety pattern for displaying light emitting characteristics; the safety pattern comprises at least one first area and at least one second area, wherein the first areas can be excited by infrared light or ultraviolet light to emit light, but antifake information cannot be written by the ultraviolet light; and the second areas can be written into the antifake information by the ultraviolet light, and can be only excited by the infrared light to emit light after the antifake information is written by the ultraviolet light. As the first areas and the second areas have different light emitting characteristics, the safety product has the characteristics of convenience to detect and high hiding performance. The invention further provides the detecting method and the detecting system for the safety product.

Description

technical field [0001] The invention relates to a security product, a detection method and a detection system thereof, and belongs to the technical field of security and anti-counterfeiting. Background technique [0002] Anti-counterfeiting technical means based on luminescent materials have a long history. At present, luminescent materials that conform to the Stokes effect, such as ultraviolet excitation and emission of visible light emission materials, that is, fluorescent materials; As well as anti-counterfeiting technical means such as paired and combined printing of fluorescent materials and infrared up-conversion materials, it has been widely used in high-end currency anti-counterfeiting and general anti-counterfeiting products (stamps, various tickets, certificates, etc.). [0003] Patent CN1720145A proposes a security pattern and its manufacturing method. The security pattern shows the same color under the sunlight light source, and shows a color change when ultravi...
