    • A method, apparatus and system for analysing and authenticating a luminescent tag are provided wherein a luminescence is triggered in the tag and relative light intensities emitted thereby measured within at least two luminescence bands. The measured intensities are compared with at least one reference tag representative of relative intensities emitted by an authentic tag to determine whether the luminescent tag corresponds with any of the at least one reference tag. If the measured intensities match the representative intensities, the luminescent tag is authenticated. A computer program to be implemented by the apparatus and system is also disclosed. Further, a method and system for verifying the authenticity of one or plural objects are disclosed, wherein each of the objects is to be associated with a respective tag. The respective tags are coded to emit light, when triggered, within at least two luminescence bands at respective predetermined relative light intensities. Having access to a reference tag representative of the predetermined intensities, the authenticity of a luminescent tag is verified by measuring intensities emitted thereby within the luminescence bands and comparing the measured intensities with the predetermined intensities.
    • 提供了一种用于分析和认证发光标签的方法,装置和系统,其中在标签中触发发光,并且在至少两个发光带内测量出由此发射的相对光强度。 将测量的强度与代表真实标签发射的相对强度的至少一个参考标签进行比较,以确定发光标签是否对应于至少一个参考标签中的任一个。 如果测量的强度与代表强度相匹配,则发光标签被认证。 还公开了由该装置和系统实现的计算机程序。 此外,公开了一种用于验证一个或多个对象的真实性的方法和系统,其中每个对象与相应的标签相关联。 各个标签被编码为当被触发时以各自的预定相对光强度在至少两个发光带内发光。 通过访问代表预定强度的参考标签,通过测量在发光带内发射的强度并将测量的强度与预定强度进行比较来验证发光标签的真实性。
