US 2017/0012996 A1 · Method and apparatus for assuring location data integrity with minimum location disclosure

Abstract

An invention relates to method and apparatus of a location assurance system and particularly, although not exclusively, the present invention also relates to method and apparatus for assuring location data integrity with minimum location disclosure. The present invention also relates to method and apparatus for assuring location data integrity with minimum location disclosure with protocols to authenticate both spatial and spatio-temporal predicates.

Claims20

Dependent claims

A method for assuring location data integrity with minimum location disclosure comprising steps of:

using Prefix-verifiable Message Authentication Codes (PMAC) to assure the integrity of the location data between at least one authenticator and at least one verifier;
using the PMAC from the previous step to authenticate/verify for spatial and spatio-temporal predicates;
and
using one or more message authentication codes indexes and one or more optimization techniques to reduce computation and communication costs.
