Abstract: To improve user data management in vehicles, a computer-implemented method, for deletion of data in a data storage of a vehicle having an HSM, includes: a) a user causing an HMI to generate an erase command for private data that is suitable to personally identify the user; b) transmitting the erase command to an ECU of the vehicle; c) identifying the user by checking a user ID stored in a user ID database and determining the existence of the user ID and, if the user ID is determined to exist, continuing in step d), otherwise continuing in step e); d) generating a request for destruction of an encryption key that is associated with the user ID and sending said request to the HSM and the HSM destroying the encryption key; and e) delete the private data indicated by the user.
