Abstract

Methods are disclosed for obtaining a unique identifier from a distinctive magnetic source configured to generate a magnetic field which is distinctively identifiable. The method comprises: receiving magnetic field intensity measurements from the distinctive magnetic source obtained by magnetic field sensor pairs relative to which the distinctive magnetic source is located in a predefined position; determining one or more magnetic field intensity differences between magnetic field sensors of each magnetic field sensor pair; assigning a predefined code associated with each magnetic field intensity difference, based on an encoding scheme that maps magnetic field intensity differences to predefined codes; and forming the unique identifier for each assigned predefined code. Systems and computers programs suitable for performing said methods for obtaining a unique identifier are also disclosed. Methods, systems and computer programs for determining a relative spatial difference between a first object and a second object are disclosed as well.
