Patent number: 11277589Abstract: A travel status recording apparatus records an image captured by a camera mounted on a vehicle, identifies personal information included in the captured image, and masks the personal information in the captured image. A server acquires a masked image corresponding to the captured image in which the personal information is masked from the travel status recording apparatus. The server determines, in response to a request from a third party, whether to restore the personal information included in the acquired masked image based on a preset restoration level. In a case where the server determines to restore the personal information, the server restores the personal information. In a case where the server determines not to restore the personal information, the server conceals the personal information.Type: GrantFiled: September 2, 2020Date of Patent: March 15, 2022Assignee: DENSO TEN LimitedInventors: Yoshikuni Miki, Hiroshi Yamada, Hiroyuki Watabe, Yasuhiko Nakano, Yuuji Uno
