1. A computer-implemented method comprising:
converting at least one numerical feature of a data point into a respective categorical form, wherein each categorical form represents a respective value range into which a numerical value of the respective numerical feature falls,
determining an identifier of a data contributor associated with the data point;
concatenating the identifier with the respective categorical form;
cryptographically hashing the identifier concatenated with the respective categorical form to generate a mark;
associating the mark with the data point to generate marked pseudonymous-anonymous data; and
transmitting the pseudonymous-anonymous data to a data platform, wherein the data point is part of a vehicle trajectory data collected by one or more sensors of a vehicle, a device, or a combination thereof, wherein the at least one numerical feature is a time of a data collection of the data point, and wherein in the respective value range is a time window.
