Digital lock

A software program product configured to control operation of a digital lock including at least two magnets including a semi hard magnet and a hard magnet, 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 configured 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 the 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, the semi-hard magnet being inside the magnetization coil, the magnetization coil being controlled by the output module for magnetization of the semi-hard magnet, which has a coercivity less than a coercivity of the hard magnet, the semi hard magnet and the hard magnet being configured adjacent to each other, the output module being 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.

A method for controlling a digital lock, the method comprising:

• providing at least two magnets including a semi hard magnet and a hard magnet configured to open or close the digital lock;
• configuring the semi-hard magnet to be inside a magnetization coil, the semi-hard magnet having a coercivity less than a coercivity of the hard magnet;
• configuring the semi-hard magnet and the hard magnet to be adjacent to each other;
• and
• configuring a change in the magnetization polarization of the semi-hard magnet to push or pull the hard magnet to open or close the digital lock.
