Patent number: 7318156Abstract: A mail receiving section receives S/MIME signature mail from a host of a member. A member checking section checks the electronic signature of the signature mail for validity and determines whether or not the member belongs to a group. If the member checking section checks that the mail is from the valid member, a mail storing section requests an archive service section to archive the mail. A signature creating section uses a secret key unique to the group to create an electronic signature of the group. A mail transmitting section transmits the mail with the electronic signature of the group to the receiver.Type: GrantFiled: January 13, 2003Date of Patent: January 8, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Masato Kurosaki, Naoyasu Terao

Patent number: 7007091Abstract: A subject name of a personal certificate is used to easily perform access control. An authentication unit implements an authentication procedure between a client terminal and a web server. The authentication unit receives a certificate from the client terminal for executing the authentication procedure, and its subject name is supplied to an element extracting unit. The element extracting unit follows a hierarchy structure of the subject name to extract a predetermined element. A right determining unit determines an access right for accessing a document based on a type and a value of the element extracted, and allocates this to a session number. A right registering unit registers a relation between the session number and the access right. Thereafter, while the session continues, an access right is allowed based on the session number.Type: GrantFiled: November 14, 2001Date of Patent: February 28, 2006Assignee: Fuji Xerox Co., Ltd.Inventors: Ryu Inada, Masato Kurosaki
