A closure () for a container comprising a connecting element () for connection of the closure to a container, a sealing device () for sealing the access to a container content and an interface () to an adapter having a coupling receptacle (). The closure () has a delivery position and a use position. In the use position, the sealing device () is open. In the delivery position, the sealing device () is sealed in a gas and liquid tight manner.

Closure for a container

A headspace extraction and analysis method for volatile compounds can be performed in automatic mode in a HS-ITEX apparatus adapted to be additionally connectable to a vacuum source. The method includes extracting the headspace by sucking volatile compounds into a sorbent-containing trap followed by desorption into the injector of a GC-MS analyzer.

Dynamic headspace vacuum transfer 'in trap' extraction method and apparatus

In one embodiment, the invention is directed to a method of reading a marking, comprising a stimulation step, wherein a physical challenge according to a predetermined challenge-response authentication scheme corresponding to the PUF is created and applied to a PUF; a detection step, wherein a response generated by the PUF in accordance with the challenge-response authentication scheme in reaction to the challenge is detected and a digital signal representing the response is generated; a processing step, wherein the digital signal is processed in order to generate a hash value of the response by application of a predetermined cryptographic hash function to the digital signal; and an output step, wherein data representing the generated hash value as a first reading result is output.

Composite security marking and methods and apparatuses for providing and reading same

The present disclosure relates to the field of anti-counterfeit protection of products. Specifically, the disclosure is directed to a method of reading with a reader device a marking comprising a physical unclonable function, PUF, and a corresponding reader device. In particular, such reader device marking can be used in connection with or can form a component of a multi-component security system, in particular of an anti-counterfeit protection system, which is also disclosed herein as part of an overall security solution for anti-counterfeit protection. The method comprises a stimulation step, wherein a physical challenge according to a predetermined challenge-response authentication scheme corresponding to the PUF is created and applied to a PUF; a detection step, wherein a response generated by the PUF in accordance with the challenge-response authentication scheme in reaction to the challenge is detected and a digital signal representing the response is generated; a processing step, wherein the digital signal is processed in order to generate a hash value of the response by application of a predetermined cryptographic hash function to the digital signal; and an output step, wherein data representing the generated hash value as a first reading result is output.

A closure () for a container comprising a connecting element () for connection of the closure to a container, a sealing device () for sealing the access to a container content and an interface () to an adapter having a coupling receptacle (). The closure () has a delivery position and a use position. In the use position, the sealing device () is open. In the delivery position, the sealing device () is sealed in a gas and liquid fight manner.

The present disclosure relates to the field of anti-counterfeit protection of products. Specifically, the disclosure is directed to a composite security marking for a physical object, in particular to an anti-counterfeit product marking. In particular, without limitation, such composite security marking can be used in connection with or can form a component of a multi-component security system, in particular of an anti-counterfeit protection system, which is also disclosed herein as part of an overall solution for anti-counterfeit protection. The composite security marking comprises a physical unclonable function, PUF, and a representation of a digital signature or of a pointer indicating a location where said digital signature can be accessed. The digital signature digitally signs a hash value resulting from application of a predetermined cryptographic hash function to data representing a response generated by the PUF in reaction to a challenge of a predetermined challenge-response authentication scheme.

Composite security marking

An electronics assembly for wireless transmission of at least one status information of an object comprises a motion sensor for detecting movement of the object. Upon detection of movement, the electronics assembly is set in a transport mode and, upon detection of an absence of a movement, the electronics assembly is set in a stationary mode. The electronics assembly is configured such that the wireless transmission of the at least one status information is effected only in the stationary mode.
