In traditional electronic comparators, the reference code is extracted from the memory to be injected into a logic circuit and compared to the user input. There is a security flaw here since a malicious user has the possibility to read the reference or send a false reference to the comparator.
The invention consists of an electronic comparator system in which the code is recorded in the comparator directly. This avoids "taking" the code out of a memory in digital form and thus ensures increased confidentiality. The comparator system uses the Extraordinary Hall Effect (EHE) and magnetic materials whose signal cannot be picked up or modified remotely.
MARKETS & APPLICATIONS
Security - access control:
● It can be integrated into any device requiring access control by electronic circuit (computers, payment terminals, identity documents, smart cards, vehicles, etc.)
● Sensor data networks for the Factory of the Future (automaton locking, machine parameters locking...)
