Four Ways to Track a Person, and How Fast Each One Names You

Not all location data is equal. The question that matters is not how precise it is, but how quickly raw signal resolves to a named individual. ALPR trades granularity for identity certainty. GPS gives you the track but makes you work to name the person. Bidstream gives you neither cleanly, just volume. Connected-car telematics is the one that does both at once, which is why it is the fastest-growing exposure of the four.

Dimension	ALPRPlate Reads	GPSDevice Location	BidstreamAd Auction	TelematicsConnected Car
Identity resolution	Near-trivialPlate maps to a registered owner through DMV records. Shortest path from signal to name.	IndirectTied to a device or ad ID first. Naming the person takes a second step: a broker or a subpoena.	WeakestKeyed to ad IDs, often noisy or IP-derived. Hardest of the three to pin to one named person.	StrongBound to the VIN and the registered owner from the factory. Identity is baked in, not inferred.
Spatial precision	CoarseA confirmed point only where a camera exists.	FineAccurate to a few meters.	InconsistentSometimes lat/long, sometimes just an IP region.	FineGPS-grade, drawn straight from the vehicle's own navigation system.
Temporal pattern	ScatteredPrecise timestamps, but movement between reads is inferred, not recorded.	ContinuousAn actual record of movement.	SporadicFires only when an app generates an ad call.	Continuous +Trip logs, speed, hard braking, dwell time, often door and ignition events.
Coverage model	Fixed-point. Intersections, lots, repo and patrol vehicles. No camera, no data.	Source-dependent. Handset, app SDKs, fitness trackers, connected-car telematics.	Broad but uneven. Depends on which apps a person runs and how often.	Whenever the vehicle is in use. No app install or camera needed, the car is the sensor.
Ease of access	Most openCommercial brokers sell to repo, insurance, and PIs. Law enforcement access is widespread, often outside warrant requirements.	Moderate frictionApp consent, broker purchase, or legal process. Location brokers have eroded the friction.	Most diffuseHundreds of auction participants see bid requests. Data leaks out the side with little accountability.	Growing fastOEMs sell to insurers and data brokers, often via consent buried in purchase paperwork. Subpoena-accessible and increasingly resold.
Retention	YearsReads persist for years, enabling historical pattern-of-life reconstruction after the fact.	VariesDepends on source and provider policy.	OpaqueVariable and hard to track once resold.	YearsOEMs and partners retain trip histories well beyond ownership in many cases.
Unit of tracking	The vehicle. Powerful when the target's car is known, weaker when it is not.	The device, and by extension the person carrying it.	The ad ID. A proxy for a device, loosely held.	The vehicle, bound to a named owner. The car identifies itself.
Best use	Confirming where a known vehicle was, and when.	Reconstructing a continuous movement track.	Population-scale patterns. Weak for tracking one named individual.	The complete movement record of a named person's vehicle, from the vehicle itself.
Speed to access	DaysHistorical reads via PI-adjacent brokers in days. Near-live hotlist pings are repo and law-enforcement tier.	GatedTrue real-time is effectively law-enforcement only, via carrier and legal process. Commercial actors get sampled history at best.	Fast w/ seatBulk feed arrives quickly if you hold an exchange seat or reseller deal. Otherwise no clean path.	Contract-gatedOEM and insurer channels are slow and contractual for commercial buyers. Subpoena for law enforcement.
Data freshness	Near-liveReads land within minutes to hours of capture. Hotlist alerts can be near-instant for privileged actors.	LiveReal-time by nature, if you can reach it. The freshness is high, the door is what is closed.	Near-liveFeeds update continuously, but the signal is noisy and not locked to one target.	LiveThe vehicle reports as it drives. Fresh at the source, delayed only by the channel you obtain it through.
Targeting a soldier	5/10Personal plate maps to home and base gates, but OPSEC rotation, base transport, and restricted on-installation camera coverage cap it. Strong off-duty, weak on-base.	8/10Fitness-app and handset leakage has already burned base perimeters and patrol routes. The continuous track is the real exposure for deployed personnel.	6/10Cheap bulk geofencing around bases and facilities is demonstrated. Coarse, but base-pattern mapping at population level is real.	6/10Maps the personal vehicle's full off-base pattern of life. Limited on-installation, and only if the soldier drives a connected car.
Targeting an executive	8/10Known, often distinctive vehicle; fixed home and office; predictable routes. Plate-to-owner plus dense business-district camera coverage make this the high-value physical-protection source.	7/10High exposure via personal device and connected-car telematics, but a protection-aware principal can be hardened. Potent with the right ad ID.	4/10Too noisy to confidently track one named principal. Better for mapping a household or a venue's foot traffic than the individual.	9/10The sharpest of the four. Identity-bound, continuous, and granular against exactly the late-model luxury vehicles executives drive. Hardest to harden short of changing cars.

Gray bars show relative strength per row, not a combined ranking. Freshness chips show recency (live to historical), not ease of access. Speed-to-access reflects a commercial or threat-actor lens; law-enforcement timelines differ and are noted in-cell. The two scored rows are ObscureIQ analytic assessments, not measured values.
