At Mobito, we take rigorous steps to ensure that all vehicle data remains fully anonymised and free of any personally identifiable information (PII). Our anonymization process ensures compliance with data protection regulations and prevents any possibility of tracking or identifying individual vehicles or drivers.
Probe Data Anonymisation
A. Remove of Identifiers
Before processing, we remove any information that could potentially identify a specific vehicle or owner, including:
Vehicle Identification Number (VIN): A unique code assigned to each car by its manufacturer
License Plate Number: The registration number assigned by authorities.
Any Other Personal Identifiers: Any other metadata that could link the data back to an individual
B. Assign Hash IDs to Data Records
To maintain the ability to analyze driving behavior without compromising anonymity, Mobito assigns hashed, temporary identifiers to data records instead of using real vehicle IDs. These include:
Unique ID:
A randomly generated identifier that represents a single vehicle
This ID remains valid for a maximum of 24 hours before being replaced
This ensures that even if multiple records come from the same vehicle, they can only be linked for one day before the connection is broken
Trip ID:
A unique identifier assigned to a single trip.
A trip is defined as the period from when a vehicle starts moving until it comes to a stop
Each time a vehicle stops, a new Trip ID is generated for the next movement.
C. Data Cut-off
To further reduce any risk of re-identifying vehicles, Mobito applies data cut-offs; deliberate gaps in data to break potential tracking patterns.
Unique ID cut-off:
A random data gap is inserted every time the Unique ID changes
The data gap ranges from 1 to 3 minutes and 150 to 350 meters
Trip ID cut-off:
A data gap is introduced at the beginning and end of every trip
The length of this gap ranges from 50 to 300 meters, preventing pinpointing the exact start and end locations of a trip
The above methods are indented to help businesses and researched analyse mobility trends while preventing long-term tracking of individual vehicles.
Origin-Destination & Standstill Events Data Anonymization
In addition to probe data, Mobito also provides origin-destination (OD) data and standstill event data. These datasets contain information about where trips start and end, as well as where vehicles remain stationary for extended periods.
Key features:
No Exact Locations: Rather than providing precise latitude and longitude coordinates, Mobito utilizes the H3 hexagonal grid system to generalize locations.
H3-Resolution-11 Precision: Each location is mapped to a hexagonal area ensuring privacy while preserving analytical value.
