A fiber Bragg grating (FBG) security component for single-party and multi-party monitoring is provided. The security component includes an optical fiber having a plurality of Bragg gratings. The Bragg gratings provide a spectral response that is randomized based on the manufacture of the security component. For single-party use, the spectral response provides a reproducible spectral signature when interrogated with an optical signal. For multi-party use, each party applies a known optical interrogation signal to the security component and applies an external stress known only to the respective monitoring party. The resulting shift in the spectral signature is unique to each monitoring party, making it extremely difficult to successfully counterfeit the security component's response for all such parties.

An insertion pin includes a pin member on which a circuit board, an inspection antenna, and an inspection chip are mounted. The circuit board includes a main circuit, a main chip, and an inspection circuit set in an open-circuit condition with respect to the inspection antenna and the inspection chip. A lock base includes a main antenna matching the main chip. When the lock base and the pin member are combined and locked together, the main chip is electrically connected with the main antenna to emit a first signal for monitoring with an identification device, and the inspection circuit is electrically connectable with the inspection chip and the inspection antenna to emit a second signal to allow a mobile phone to carry out quality control to determine if the first signal is in normal operation. Cutting off the insertion pin terminates both the first and second signals.

In accordance with a first aspect of the present disclosure, an integrated circuit is provided, comprising a current source and a reference capacitor, the integrated circuit being configured to: inject, using said current source, a first current in an external measurement capacitor and determine a first amount of time within which a resulting voltage on the measurement capacitor reaches a voltage threshold; inject, using said current source, a second current in the reference capacitor and determine a second amount of time within which a resulting voltage on the reference capacitor reaches said voltage threshold; detect a change of the capacitance on the measurement capacitor using a difference between the first amount of time and the second amount of time. In accordance with a second aspect of the present disclosure, a corresponding measurement method is conceived.

The present invention relates to a smart and secure label stock with security features. The present invention relates to a label stock produced from a substrate utilizing adhesive and liner materials and having a plurality of security features on the rear side of the substrate made using specialized inks and various authentication features for different applications.

A security device (1) comprising an optically transparent layer (3) including a repeating first array of separate optical focussing elements (3) (e.g. having translational symmetry) wherein a pitch distance between repeated elements in the first array is a first pitch value (A). The device also includes a repeating second array of separate image elements (6) (e.g. having translational symmetry) collectively defining an image viewable through the first part. The device is structured such that a pitch distance between repeated or successive elements in the second array is a second pitch value (B) wherein the ratio (A/B) of the first pitch value and the second pitch value has a value, A/B=n±Δ, that differs from a positive integer value, n, according to an absolute difference, Δ, not exceeding 0.01 and not less than 0.001.

The invention relates to a peel detection label that is a laminate including a support, a pattern layer formed in a part of the surface of the support, and a pressure-sensitive adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order, in which the low modulus layer (X) has an n-layered structure (where n is an integer of 1 to 10) having a surface in contact with the support and the pattern layer and a surface in contact with the high modulus layer (Y), and the low modulus layer (X) satisfies a specific thickness-average shear storage elastic modulus.

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.

The present invention relates to a closure mechanism, such as a label construction, for a wide variety of packages. The closure mechanism may provide for a security means as well and can be provided with a radio frequency identification (RFID). The closure mechanism may comprise at least one label having at least one RFID device on either a first or second face of the label such that the label is applied to a package wherein the package is subject to a first and second state conditional upon the positioning of the at least one label positioning. The present invention also provides for a method of making and utilizing the label on at least one packaging.

According to a first aspect of the present disclosure, an electronic tamper detection device is provided, comprising a tamper loop and a deformable component, wherein a deformation of said component indicates that the tamper loop has been broken. According to a second aspect of the present disclosure, a corresponding method of producing a tamper detection device is conceived.
