To provide a data collection apparatus that can collect data from a vehicle so that activities of an individual possessing the vehicle cannot be guessed.SOLUTION: A data collection apparatus includes: a storage unit that stores a vehicle identifier for identifying a vehicle; and an associating unit that associates, when a time of generation of data that represents road environment around the vehicle and is generated by a sensor provided on the vehicle is included in a first period, a first hash value obtained by irreversibly transforming the vehicle identifier with the data, and associates, 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 second hash value being obtained by irreversibly transforming the vehicle identifier.SELECTED DRAWING: Figure 6
【課題】車両を保有する個人の行動を推測できないように車両からデータを収集可能なデータ収集装置を提供する。【解決手段】データ収集装置は、車両を識別する車両識別子を記憶する記憶部と、車両に設けられたセンサにより生成された車両の周囲の道路環境を表すデータの生成時刻が第1の期間に含まれる場合、車両識別子を不可逆変換した第1ハッシュ値をデータに関連づけ、生成時刻が第1の期間と異なる第2の期間に含まれる場合、車両識別子を不可逆変換した、第1ハッシュ値と異なる第2ハッシュ値をデータに関連づける関連づけ部と、を備える。【選択図】図6
