A method for checking an authenticity feature having an optical storage phosphor, to an apparatus for checking, an authenticity feature and to a value document having an authenticity feature. The authenticity feature has an optical storage phosphor. The optical storage phosphor may be subjected to at least one query sequence, respectively comprising at least a first readout process and a second readout process. Respectively at least a first and a second readout measurement value are captured, which respectively are based on the detection of an optical emission in response to the respectively first or the respectively second associated readout process. A readout measurement value time series is respectively associated with the at least one query sequence, and is respectively associated with the query sequence for determining a dynamic behaviour from the readout measurement value time series under the respectively associated query sequence is evaluated in a further step.

The invention provides methods for stably binding and immobilizing deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate. The alkaline conditions are produced by mixing the deoxyribonucleic acid with an alkaline solution having a pH of about 9.0 or higher, and contacting the deoxyribonucleic acid to the substrate. The immobilized DNA can be used as a taggant and can be used in combination with other detectable taggants, such as optical reporters. Methods for authentication of a DNA marked object are also provided.

A security device including an array of lines printed or otherwise provided on a substrate, the lines including materials which have the same appearance under visible light illumination but which appear different from each other in the visible under a combination of visible and non-visible, ultraviolet illumination. At least some of the lines in the array appear different from other lines under the combination of visible and non-visible, ultraviolet illumination. A second, surface relief array of lines imposed on the first array, the orientation, line widths and spacings of the first and second arrays being such that the device exhibits a variable appearance as it is tilted while exposed to the combination of visible and non-visible illumination.

A capsule placed on a beverage bottle. The capsule includes a capsule material layer and at least two layers of security ink on the capsule material layer. Each of the at least two layers has a different chemical composition. At least one layer of the at least two layers includes a first composition having flakes exhibiting full reflection of light received at a predetermined wavelength.

A microcapsule, method, and article of manufacture are disclosed. The microcapsule includes an outer shell, a molecular sensitizer, a molecular annihilator, and an inner shell separating the molecular sensitizer from the molecular annihilator. The method includes forming microcapsules, each microcapsule having an outer shell, a molecular sensitizer, a molecular annihilator, and an inner shell separating the molecular sensitizer from the molecular annihilator. The article of manufacture includes at least one of the microcapsules.

A secure document includes a fluorescent barcode and a fluorescent filler printed onto a substrate. The fluorescent barcode is printed using a first fluorescent ink of a first color and the fluorescent filler is printed using a second fluorescent ink of a second color that is different than the first color. In order to read the fluorescent barcode, the secure document must be illuminated with ultraviolet and/or infrared light. Then, a color filter must be used to filter the fluorescent filler out, leaving the fluorescent barcode visible.
