Privacy by design, accountability on demand.
A taxi you hail on the street leaves no record of the car, the driver, or the route, and handing a stranger your name to feel safer is its own exposure. Parousya takes a quiet note of the vehicle through a short range signal while the rider stays anonymous to the driver, so the record exists if it is ever needed and an authorised family member can follow the journey.

Unbooked rides leave no trace
A taxi hailed on the street is off the books. There is no record of the car, the driver, or the route, so if anything goes wrong there is nothing to go back to.
Identity is the price of feeling safe
Handing a stranger a name or a number to feel safer is its own exposure. Safety and privacy pull against each other, and the rider usually pays with the privacy.
No one outside the car can follow
If a ride goes wrong there is no way for anyone outside the vehicle to know where it went. Concern from a family member has nothing to act on.
A quiet note of the vehicle
The method registers the vehicle through a short range signal while the rider stays anonymous to the driver. The record forms without an exchange of identity in the car.
The record is there if needed
The two devices never connect directly and nothing is sent until it needs to be, under parent patent US10657515B2. If something goes wrong, the pairing held by the server is evidence of the car and the ride.
A family member can follow along
Third party querying, a capability of divisional patent US11392923B2, lets an authorised person such as a family member follow a journey in progress. It is a specific permission, not an open feed.
Privacy by design, accountability on demand
Presence is recorded, not broadcast. The rider stays anonymous to the driver, and the record surfaces only when someone entitled to it asks.
Common questions
- How can a taxi ride be recorded without booking it?
- The vehicle broadcasts a short range signal that the rider's phone notes, and the pairing registers the car with a central server. Even a ride hailed on the street leaves a record.
- Does the driver learn who I am?
- No. The rider stays anonymous to the driver. The method records the vehicle, not an identity handed across the seat.
- Who can follow my journey?
- Third party querying, which belongs to divisional patent US11392923B2, lets an authorised person such as a family member follow the journey. It is a granted permission, not open to everyone.
- What does privacy by design mean here?
- Nothing is sent until it needs to be. The record is held quietly under parent patent US10657515B2 and surfaces only on demand, so you get accountability without giving up anonymity during the ride.
