Abstract
The invention provides a digital lock including at least two magnets. One magnet is a semi hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

15. A software program product configured to control operation of a digital lock, the digital lock comprising
a semi-hard magnet; - and
a hard magnet, wherein the semi-hard magnet and the hard magnet are configured adjacent to each other; the software program product comprising a processing module configured to operate the digital lock, the processing module comprising; an input module configured to receive an input from a user interface; an authentication module configured to authenticate the input received by the user interface; a database to store identification information of one or more users; and an output module configured to control a power source to power a magnetization coil to change magnetization polarization of the semi;
hard magnet in response to successful identification of a user, and configured to control the hard magnet to open or close the digital lock, wherein the output module is configured to change the magnetization polarization of the semi-hard magnet to push or pull the hard magnet to open or close the digital lock. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 30)

28. A method for controlling a digital lock, the method comprising;
-
changing magnetization polarization of a semi-hard magnet, of the digital lock, to a first state; responsive to the change of the magnetization polarization to the first state, pushing or pulling a hard magnet, of the digital lock, to open the digital lock; changing the magnetization polarization of the semi-hard magnet to a second state; and responsive to the change of the magnetization polarization to the second state, pushing or pulling the hard magnet to close the digital lock, wherein the semi-hard magnet and the hard magnet are configured adjacent to each other.
