A liner in a label-liner combination is provided with a die cut portion made in the liner. The die cut portion is aligned with at least one edge in a label and a front side of the liner is attached to a backside of the label. The die cut portion of the liner is adapted to be removed from the liner when the label is removed from the label-liner combination. Dimensions, and orientation, and a location of the die cut portion in the liner are adapted to allow the label to be removed from the label-liner combination and applied to a surface by digits of a hand without touching an adhesive coating on the backside of the label and adapted to maintain proper printer waste liner spool operations when the liner is wound after application of the label.

A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. The physical card may include disposed thereon a single address operable to receive digital bearer assets in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Other decentralized computing platforms utilize different address generation protocols, thus preventing use of a single address on those other platforms. A set of addresses is generated, each address corresponding to a given decentralized computing platform. Each address is based on a same underlying key-pair, and a primary address is selected from the set for a given card. The remaining addresses in the set are stored, without storage of the public key or private key, and returned in a response to a request for additional addresses of the currency card.

A plasmonic structure having an identifier pattern indicating a genuine product for preventing counterfeiting, falsification or reuse, includes a metal layer; a photoconversion pattern layer including a plurality of photoconverting nanoparticles disposed in a pattern on and in direct contact with the metal layer; a metal pattern layer including a plurality of metal particles disposed in a pattern on and in direct contact with the photoconversion pattern layer; and an adhesive film disposed on the metal pattern layer. An identifier pattern indicating a genuine product is easily identified even by visual inspection after irradiation with infrared light irradiation. The plasmonic structure is fundamentally impossible to re-assemble after deformation of the plasmonic structure caused by disassembly of a product or packaging container, thereby preventing counterfeiting, falsification or reuse.

A method, comprising: providing a combination of a package and a label attached to the package, wherein the label comprises a fluorescent substance, illuminating the label with excitation light so as to cause the label to emit fluorescence light, capturing an image of the label by using an imaging unit, and detecting the position of the label by analyzing the captured image and/or detecting a degree of adhesion of the label by analyzing the captured image.

A liner in a label-liner combination is provided with a die cut portion made in the liner. The die cut portion is aligned with at least one edge in a label and a front side of the liner is attached to a backside of the label. The die cut portion of the liner is adapted to be removed from the liner when the label is removed from the label-liner combination. Dimensions, and orientation, and a location of the die cut portion in the liner are adapted to allow the label to be removed from the label-liner combination and applied to a surface by digits of a hand without touching an adhesive coating on the backside of the label and adapted to maintain proper printer waste liner spool operations when the liner is wound after application of the label.

A physical multi-component article with cross-component deterministic values and underlying value protection (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for a digital wallet on a decentralized computing platform, like a blockchain-based decentralized computing platform. Private access information, like private key ciphertext and key or passphrase by which the private key ciphertext may be converted to plaintext, are physically concealed with tamper-evident components such that a user can readily determine by visual inspection of the apparatus whether, and what, private access information was divulged. In some examples, a user is required to activate one or more tamper-evident features, thereby altering a visible state of the apparatus, to access certain functions of a digital wallet corresponding to the apparatus.

The disclosed embodiments provide a method for tamper-evident shipment or storage of goods. An Electrical Shield pattern is embedded in or printed on a substrate with other electrical, optical, and electronic components, communication components, semiconductors, which are attached or printed on a substrate to form a shipment bag used as a shipping container. The shield pattern can be made variable between different bags by using algorithms entered into a printer control system. The shipment bag with its components can then be assigned a unique signature which differentiates each bag. Application of encryption methods serves to guarantee the shipped goods are authentic and that were not tampered with during shipment. Digital signal processing is used to generate pedigree information, which may include items such as shipping location, serial numbers, sensor information, and lot numbers for the goods. The information related to the history of tampering attempts and other sensor status can be placed in encrypted form in an RFID tags or control or monitoring electronics which can be read by a mobile phone application or sent to a remote cloud-based server.

A label to identify an object has an inscribable layer composite for receiving a first, visible inscription to identify an object, an adhesive film for adhering the label to an object, and an active substance, which, when contacting the object surface, penetrates into and/or acts on the object surface. The active substance is disposed on the label rear side in a structured active surface layer, on, in, or underneath the adhesive film. The structured active substance layer includes a partial surface region or multiple partial surface regions of the label base surface. When the label is adhesively affixed to the object surface, the active substance on the label rear side selectively contacts the object surface in the structured active substance surface region. Within the base label surface, the structured active substance layer has the shape and/or contour of a further, initially-invisible inscription, identification or item of information.

Sealing a package with a visually transparent sealing label is described. The visually transparent sealing label contains an ultraviolet blocking component to prevent transmission of ultraviolet radiation through the label to the surface of the package. The package comprises an activatable component that upon excitation with ultraviolet radiation emits luminescence. The presence of the sealing label on the package may be verified by illuminating the sealing label with ultraviolet radiation and by observing whether the level of luminescence from the package material under the sealing label is lower than a limit value.

Disclosed are various embodiments of multi-layer identifier labels. In one embodiment, a multi-layer identifier label includes an upper layer bearing a public identifier, a lower layer bearing a private identifier, and an adhesive backing below the lower layer. The upper layer may be removably attached to the lower layer, and the lower layer may be non-visible underneath the upper layer. Peeling away the upper layer to reveal the lower layer may be a tamper-evident action.
