Abstract

PURPOSE:To preclude an illegal copy and a wrong copy from being taken by an illegal information processor by enabling an information processor to copy information with ciphered information permitted by a copy control manager. CONSTITUTION:A ticket 7 for obtaining copy information is ciphered copy permission information and can be deciphered with a deciphering key that a specific information processor has. The information processor 11 makes a communication with an information processor 13 having a copy control manager 8 and a copy control server 5 requests the copy control manager 8 to send the ticket for obtaining a copy of information A. The copy control manager 8 verifies the requesting information processor 11 and judges whether the information processor 11 can hold the copy of the information A by checking an access right data base 9. When the information processor 11 can have the copy of the information A of the information processor 12, the ticket for the permission is issued and sent to the information processor 11. Consequently, the information is prevented from being copied illegally or incorrectly.
