Location is a contextual signal, not independent proof that a person is physically present. High-impact decisions require separate transaction and account controls.
Evaluation approach
Assess permission, accuracy, timestamp and application context together. Risky-environment signals may help, but legitimate location errors also occur.
Application example
For delivery confirmation, combine location with the order workflow and other business evidence. Offer an alternative in areas with poor GPS reception.
Limits and considerations
RASP must not be interpreted as eliminating every form of location spoofing.
The evidential strength of a coordinate
A coordinate is a measurement reported by a device, not absolute proof of a person's presence. Measurement quality, network and platform conditions affect results. One unusual coordinate does not directly establish malicious intent.
Use workflow consistency and server records in the assessment. A delivery record, for example, can be bound to its task and time context. RASP adds risk information without itself verifying the physical event.
Checks and decisions
- Check data age
- Account for accuracy
- Use alternative evidence
Weight location according to the cost of an incorrect decision.
