Abstract
An apparatus for collecting data includes a memory that stores a vehicle identifier for identifying a vehicle; and a processor configured to associate, when a time of generation of data representing road environment around the vehicle is included in a first period, a first hash value with the data and to associate, when the time of generation is included in a second period different from the first period, a second hash value different from the first hash value with the data. The data is generated by a sensor mounted on the vehicle. The first hash value and the second hash value are obtained by irreversibly transforming the vehicle identifier.
