    • A scanner (200) is arranged to detect a unique spectral signature acquired from a sample (230) coded with a security marker (700) made up from one or more overt or covert coloured features (704a-704b) having known and uniquely identifiable spectral characteristics. More particularly, a narrowband light source (218), operating in the middle/near ultraviolet to short/near infra-red wavelength ranges, pulses light onto the security marker fixed to or formed in the sample (230). A lens system (222, 216) collects spectral data for analysis by a processing engine (201), such as a smartphone. The light source (218), which may be an array of differently coloured LEDs (224), selectively illuminates the security marker with discrete wavelengths as LEDs are selectively energized. The coloured features (704a-704d) are realized by combinations of dyes, pigments or inks that may fluoresce that are difficult to replicate and therefore typically pantone-based. The coloured features each have unique spectral responses, i.e. spectral characteristics, in the presence of incident EM radiation, so coding a bona fide product with a security marker made up from pre-selected coloured features producing the unique signature allows validation of the product. Specifically, by using the scanner and executing analysis code, the processing engine (201) is configured to make a quick comparison of the spectral peak and trough data acquired from the security marker against stored reference spectral signature corresponding to the marker on the product and to provide an indication (or not) of correspondence.
    • 扫描仪(200)被布置为检测从用具有已知且可独特识别的光谱的一个或多个明显或隐藏着色特征(704a-704b)构成的安全标记(700)编码的样本(230)获取的独特光谱特征 特点。 更具体地说,工作在中/近紫外到近/近红外波长范围的窄带光源(218)将光脉冲到固定在样品(230)上或形成在样品(230)中的安全标记上。 透镜系统(222,216)收集用于由诸如智能电话的处理引擎(201)分析的光谱数据。 可以是不同颜色的LED(224)的阵列的光源(218)在LED被选择性地通电时以离散波长选择性地照亮安全标记。 有色特征(704a-704d)通过染料,颜料或墨水的组合来实现,所述染料,颜料或墨水可以发荧光,难以复制并且因此通常是基于泛基的。 在存在入射EM辐射的情况下,彩色特征各自具有独特的光谱响应,即光谱特性,因此使用由预先选择的彩色特征构成的安全标记对真正产品进行编码,从而产生独特签名,以允许验证产品。 具体地,通过使用扫描仪并执行分析代码,处理引擎(201)被配置为快速比较从安全标记获取的光谱峰值和谷值数据与对应于产品上的标记的存储的参考光谱特征并且 提供信函的指示(或不指示)。
