Controlling access to a restricted physical space

A method for controlling access to a restricted physical space, the method being performed by an electronic lock, the method comprising:

• receiving an access request from a requesting entity;
• obtaining, over local communication, a first location indication, indicating a location of a first location source;
• obtaining, over local communication, a second location indication, indicating a location of a second location source being distinct from the first location source;
• obtaining a set of at least one limited geographic area;
• determining that a first condition is true, wherein the first condition is that the first location indication points to a location within a limited geographic area of the set;
• determining that a second condition is true, wherein the second condition is that the second location indication points to a location within the same limited geographic area of the set as the first location indication;
• determining that a third condition is true, wherein the third condition is that authorisation is granted based on the access request;
• and
• setting the electronic lock in an unlocked state.

An electronic lock for controlling access to a restricted physical space, the electronic lock comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the electronic lock to:
• receive an access request from a requesting entity;
• obtain, over local communication, a first location indication, indicating a location of a first location source;
• obtain, over local communication, a second location indication, indicating a location of a second location source being distinct from the first location source;
• obtain a set of at least one limited geographic area;
• determine that a first condition is true, wherein the first condition is that the first location indication points to a location within a limited geographic area of the set;
• determine that a second condition is true, wherein the second condition is that the second location indication points to a location within the same limited geographic area of the set as the first location indication;
• determine that a third condition is true, wherein the third condition is that authorisation is granted based on the access request;
• and
• set the electronic lock in an unlocked state.

A non-transitory computer readable medium storing a computer program for controlling access to a restricted physical space, the computer program comprising computer program code which, when executed on an electronic lock, causes the electronic lock to:

• receive an access request from a requesting entity;
• obtain, over local communication, a first location indication, indicating a location of a first location source;
• obtain, over local communication, a second location indication, indicating a location of a second location source;
• obtain a set of at least one limited geographic area;
• determine that a first condition is true, wherein the first condition is that the first location indication points to a location within a limited geographic area of the set;
• determine that a second condition is true, wherein the second condition is that the second location indication points to a location within the same limited geographic area of the set as the first location indication;
• determine that a third condition is true, wherein the third condition is that authorisation is granted based on the access request;
• and
• set the electronic lock in an unlocked state.
