摘要:
A time certification server includes a receiving section that receives an issue request for a time certification code and terminal information; a temporal change information input section that inputs temporal change information; a first code generating section that generates a first code based on the temporal change information and outputs the first code; a second code generating section that generates a second code based on the terminal information and the first code and outputs the second code; a transmitting section that transmits the second code to the terminal apparatus as a time certification code; a time certification code memory section that stores the time certification code in correlation with time; and a certification processing section that searches the time certification code memory section by using the time certification code received, thereby obtaining time, and outputs certification information based on the time obtained to the terminal apparatus.

摘要:
It is an object to provide a certification system designed for security patrol, for example, that certifies a patrolled time and a patrolled site in security patrol rounds. It is another object to certify the time when an image was taken and the site where the image was taken, for example, by attaching information about certified time and certified site to the image. The certification system includes a GPS satellite 10 that supplies location information on the earth, a weather satellite 20 that supplies weather information on the earth, information processing equipment 30 that is carried in security patrol rounds, a certificate issuing server 40 that certifies time information and location information, an information storage server 50 that stores certified time information and certified location information as well as an image with the certified time information and certified location information attached thereto, a verification unit 60 that verifies the time when the image was taken and the site where the image was taken, and a network 70 that interconnects the information processing equipment 30, the certificate issuing server 40, the information storage server 50, and the verification unit 60.
