Abstract:
A processor is provided that binds itself to a circuit such that the processor cannot be subsequently reused in other circuits. On a first startup of the processor, a memory segment of an external volatile memory device is read to obtain information prior to initialization of the memory segment. An original/initial identifier may be generated from the information read from the memory segment. The original/initial identifier may then be stored in a non-volatile storage of the processor. On subsequent startups of the processor, it verifies that the processor is still coupled to the same external volatile memory device by using the stored identifier. For instance, on a subsequent startup, the processor again reads the same memory segment of the external memory device and generates a new identifier. If the identifier matches the previously stored identifier, then the processor may continue its operations; otherwise the processor is disabled/halted.
Abstract:
A system is provided for inside-to-outside or outside-to-inside cryptographic coding that facilitates product authentication along a distribution channel. An association of authenticated, secured codes is generated between inner items (e.g., pharmaceutical doses such as pills, capsules, tablets) and outer items (e.g., packaging containing inner items). For instance, an inner code associated with a first item is used to generate (at least partially) an outer code associated with a second item that contains one or more first items. This process may be repeated multiple times with codes for outer items being a function of codes for inner items. The sequence of items may be authenticated by the dependent relationship between their codes.
Abstract:
Disclosed is an apparatus, system, and method to utilize a plurality of road markers to aid a vehicle in merging into a lane. The lane that the merging vehicle desires to merge into is determined. Further, the position of the merging vehicle is determined. Target vehicles are then notified about the merging vehicle utilizing the plurality of road markers.
