US Patent 11387997 Constrained key derivation in geographical space

The technology disclosed herein provides an enhanced cryptographic access control mechanism that uses a cryptographic keys that are based on location data. An example method may include: determining location data of a computing device; transforming the location data in view of conversion data associated with the computing device, wherein the conversion data causes a set of alternate location data values to transform to a specific cryptographic value; creating, by a processing device, a cryptographic key in view of the transformed location data; and using the cryptographic key to enable access to a protected resource.
