Authentication apparatus, authentication method, and program
First Claim
1. An authentication apparatus that authenticates an identifier (hereinafter referred to as “
- ID”
) allocated to each user and that comprises a generating section, a storing section, a sending section, an updating section, a receiving section, and an authenticating section, wherein said generating section generates a presentation symbol string for receiving a next authentication request to an authenticated ID;
said storing section stores a transformation rule and a sending destination of the presentation symbol string to be associated with each ID;
said sending section sends “
the presentation symbol string generated by said generating section”
to “
the sending destination of the presentation symbol string stored in said storing section to be associated with the authenticated ID”
;
said updating section causes said storing section to further store the presentation symbol string sent by said sending section to be associated with the authenticated ID to perform update;
said receiving section receives an authentication request that designates an ID and a transformed symbol string; and
said authenticating section causes authentication of the ID to succeed when a condition is satisfied where “
the transformed symbol string received by said receiving section matches a transformation result obtained by applying. ‘
the transformation rule stored in said storing section to be associated with the ID designated by the authentication request received by said receiving section’
to ‘
the presentation symbol string stored in said storing section to be associated with the corresponding ID’

Abstract
A generating section generates a presentation symbol string for receiving a next authentication request to an authenticated ID, a storing section stores a transformation rule and a sending destination of the presentation symbol string to be associated with each ID, a sending section sends “the generated presentation symbol string” to a display terminal, which is “the sending destination of the presentation symbol string stored in the storing section to be associated with the authenticated ID”, an updating section causes the storing section to further store the presentation symbol string sent to be associated with the authenticated ID to perform update, a receiving section receives an authentication request that designates an ID and a transformed symbol string from an access terminal, and an authenticating section causes authentication of the ID to succeed when a condition is satisfied where “the received transformed symbol string matches a transformation result obtained by applying ‘the transformation rule stored to be associated with the ID designated by the received authentication request’ to ‘the presentation symbol string stored to be associated with the ID’.”

9. An authentication system that comprises an authentication apparatus and a presentation terminal and that authenticates an identifier (hereinafter referred to as “
- ID”
) allocated to each user,(a) said authentication apparatus comprising a seed generating section, a storing section, a seed sending section, an updating section, a receiving section, and an authenticating section, wherein said seed generating section generates a seed for receiving a next authentication request to an authenticated ID;
said storing section stores a transformation rule and a sending destination of the seed to be associated with each ID;
said sending section sends “
the seed generated by said seed generating section”
to “
the sending destination of the seed stored in said storing section to be associated with the authenticated ID”
;
said updating section causes said storing section to further store the seed sent by said seed sending section to be associated with the authenticated ID to perform update;
said receiving section receives an authentication request that designates an ID and a transformed symbol string; and
said authenticating section causes authentication of the ID to succeed when a condition is satisfied where “
a transformed symbol string received by said receiving section matches a result obtained by applying ‘
the transformation rule stored in said storing section to be associated with the ID designated by the authentication request received by said receiving section’
to ‘
a presentation symbol string generated by a predetermined procedure’
from “
the seed stored in said storing section to be associated with the ID’
”
; and
(b) said presentation terminal generates a presentation symbol string by a predetermined procedure from the seed sent from said authentication apparatus, and presents the generated presentation symbol string to a user to which the ID is assigned.

10. An authentication method that authenticates an identifier (hereinafter referred to as “
- ID”
) allocated to each user by use of “
a storing section that stores a transformation rule and a sending destination of a presentation symbol string to be associated with each ID” and
that comprises a generating step, a storing step, a sending step, an updating step, a receiving step, and an authenticating step,wherein said generating step generates a presentation symbol string for receiving a next authentication request to an authenticated ID;
said sending step sends “
the presentation symbol string generated by said generating step”
to “
a sending destination of the presentation symbol string stored in said storing section to be associated with the authenticated ID”
;
said updating step causes said storing section to further store the presentation symbol string sent by said sending step to be associated with the authenticated ID to perform update;
said receiving step receives an authentication request that designates an ID and a transformed symbol string; and
said authenticating step causes authentication of the ID to succeed when a condition is satisfied where “
the transformed symbol string received by said receiving step matches a transformation result obtained by applying ‘
the transformation rule stored in said storing section to be associated with the ID designated by the authentication request received by said receiving step’
to ‘
the presentation symbol string stored in said storing section to be associated with the ID’
