Patent number: 10679223Abstract: 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.Type: GrantFiled: December 15, 2017Date of Patent: June 9, 2020Assignee: Merck Patent GmbHInventors: Thomas Endress, Daniel Szabo, Fabian Wahl

Patent number: 10618726Abstract: 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.Type: GrantFiled: December 8, 2017Date of Patent: April 14, 2020Assignee: SIGMA-ALDRICH INTERNATIONAL GMBHInventors: Fabian Wahl, Gerd Hayenga, Bastian Bachmann, Samuel Schindler, Martin Meyer
