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.

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 heat transfer label includes a carrier, a graphic layer, a barrier layer, and an adhesive layer. The barrier layer may be formed from a substantially solid formulation comprising a functional polyol component and a functional polyisocyanate component, wherein the functional polyol component and the functional polyisocyanate component reacts with each other to form the barrier layer configured to block dye migration.

The present disclosure describes timer devices that include a timer to monitor a time period and a signalling apparatus that provides an alert signal on expiry of the time period. In some embodiments, a label assembly is provided including first and second labels releasably connected to each other, each label each including a timer and signalling apparatus, In some embodiments, a label is provided with first, second and third portions, the first and second portions including respective fixing portions and the third portion including a timer and signalling apparatus. In some embodiments a timer assembly is provided where movement of a timer unit to a second position initiates monitoring of a predetermined time period, in some embodiments, a label assembly is provided that includes a timer and signalling apparatus and an elongate portion that forms a closed loop by extending into a through hole of the label assembly, in some embodiments, a label that includes a timer and signalling apparatus is provided in the form of a wristband. In some embodiments, a label that includes a timer and signalling apparatus is provided that includes a transparent or translucent fixing portion.

A cutting plotter film with anti-counterfeit effect includes: a heat-resistant layer; a stripe-embossed layer having releasing property and bonded on the heat-resistant layer, the stripe-embossed layer being formed with a stripe-embossed surface; a character film layer disposed on the stripe-embossed surface of the stripe-embossed layer, having a contact surface in contact with the stripe-embossed surface, the contact surface being formed with anti-counterfeit stripes; and a heat bonding layer disposed on the character film layer. Figures/characters are cut/engraved on the character film layer and the heat bonding layer. The cutting plotter film is placed on a product and heated to transfer and adhere the figures/characters onto the product.

Described herein are tamper-evident adhesive seals for sealing articles, containers, and other enclosure in which a covert tamper evidencing agent is included in an adhesive sealing material. The presence of the covert tamper evidencing agent reveals evidence of tampering when exposed to UV light.

A tamper proof locking mechanism incorporating a first fixture for attachment to an index protective cover, a second fixture for attachment to an instrument, and a third fixture for connecting the first fixture to the second fixture. The first fixture may have a receptacle, the second fixture may have a plate with an opening, and the third fixture may have a protrusive structure that fits into the receptacle of the first fixture and into the opening in the plate to connect the first fixture to the second fixture. The protrusive structure may have a rivet that is partially embedded with a plastic-like material that reveals tampering when an attempt is made to break a connection between the first fixture and the second fixture.

A visual-information security system that includes an information security label positioned to conceal visual information on a substrate. The information security label may include a spiral-shaped cut (or other complex shape) within the body of the label and a pull-tab, such that when a user pulls on the tab, the label peels off of the substrate in a spiral pattern, revealing the information concealed beneath the label. The complex-shaped cut makes reapplication of the label difficult and evident, thus providing security to consumers. The label may include multiple layers of material, for example, a peel-off layer and an adhesive layer.
