Problems solved by technology

However, even some systems utilizing these two detectors do not allow their acquisition parameters such as integration time and excitation light intensity to be set completely independently
Furthermore, none of the above methods fully benefit from the information available in the camera image, since it does not analyze its spectral properties prior to analyzing the information recorded by the spectrometer

Embodiment Construction

[0040]The present invention relates to a system and method enabling identification, authentication, tracking and location of tagged products from any distance with a high degree of security. The system includes a reading module, a processing module and a database containing stored tag identities. The tag's identity is defined by two distinct features: a luminescent spatial pattern and a unique spectral signature. The label contains or forms a spatial pattern and includes luminescent material, in particular luminescent particles. This allows the authentication of the product by detecting the two characteristics with the reading module, processing the information and confirming the identity of the tag against the information contained in the database. This overall procedure enables the identification and certification of products. Additionally, the present system enables the display of the exact location of the tag through a combination of optical measurements and global posit...

Abstract

The invention relates to a system (100) and method for identifying and authenticating a tag defined by at least a spatial pattern and the spectral signature of luminescent particles. The system comprises a reading module (110), a processing module (120) and a database (130) containing the stored tag identities. The spatial pattern and spectral signature are acquired by an imaging unit (111) and a spectral unit (112) respectively in a sequential manner, the acquisition being synchronized with different excitation light pulses. The validation of the tag comprises the use of background and signal acquired by both the imaging unit (111) and the spectral unit (112).

Description

technical field [0001] The present invention relates to systems and methods for identifying and authenticating labels applied to various items as identification and authentication means. Background technique [0002] Product positive identification numbers, their tracking and certification have been applied and used in many industrial fields and are constantly being developed and improved. Product marking for identification, authentication and traceability purposes is increasingly being applied in many fields of industry. Security markings of various degrees of complexity exist and are applied to items and products to help answer the question of whether a given product is genuine or counterfeit. In fact counterfeiting is a worldwide problem that causes huge economic losses and negatively affects consumers and producers. To eliminate this problem, anti-counterfeiting technologies are constantly being developed, including new security marks and modified readers. Such securi...
