1. A system comprising:
at least one hardware processor; and
a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to:
receive, by a first radio frequency (RF) receiving device, an RF data transmission from an RF transmitter,
analyze the received RF data transmission to estimate at least one RF feature,
construct, based on said at least one RF feature, an RF fingerprint of said RF transmitter which is specific to said first RF receiving device, and
modify said RF fingerprint to generate a modified RF fingerprint for use by a second RF receiving device, by applying, to said RF fingerprint, a conversion function reflecting a differential between respective contribution values associated with each of said first and second receiving devices.
