Abstract: Provided is an off-line two-factor user authentication system. The off-line two-factor user authentication system is designed to use, as a password, a one-time-password derivation rule to be applied to certain pattern elements included in a presentation pattern at specific positions so as to create a one-time password, and further use, as a second authentication factor, information identifying a client to be used by a user. A plurality of pattern seed values each adapted to uniquely specify a presentation pattern in combination with a client ID, and a plurality of verification codes corresponding to respective ones of the pattern seed values, are stored in an off-line two-factor authentication client. A presentation pattern is created based on a selected one of the pattern seed values and a client ID, and an entered one-time password is verified based on a verification code corresponding to the selected pattern seed value.

Abstract: Provided is a two-actor user authentication system with a reduced risk of leakage of authentication information. The two-factor user authentication system is designed to use, as a password, a one-time-password derivation rule to be applied to certain pattern elements included in a presentation pattern at specific positions so as to create a one-time password, and further use, as a second authentication factor, information identifying a client to be used by a user. An authentication server is operable to generate a pattern seed value adapted to uniquely specify a presentation pattern in combination with a client ID, and transmit the pattern seed value to an authentication-requesting client. The authentication-requesting client is operable to create a presentation pattern based on a client ID acquired therefrom, and display the presentation pattern to allow a user to enter thereinto a one-time password based on the presentation pattern.

Abstract: It is intended to achieve a user authentication system capable of forcibly presenting a content to a user. Provided is a content presentation-type authentication system designed to allow a client to perform a content presentation-type user authentication in which user authentication is performed in such a manner that a plurality of pattern elements arranged in a given pattern are presented as a presentation pattern to a user who intends to be authenticated, and a one-time password derivation rule is used as a password of the user and applied to certain ones of the pattern elements located at specific positions in the presentation pattern to create a one-time password, and a content is forcibly presented to the user in connection with the user authentication.

Abstract: A cylindrical linear motor capable of solving the problem that a leak flux links an aluminum frame at both ends of an armature of a conventional cylindrical linear motor, which causes a viscous braking force as a motor brake force, is provided. The cylindrical linear motor armature 20 includes a plurality of cylindrical coils 20a arranged in the axial direction in a cylindrical yoke 20b formed by a magnetic material and frames 20d and 20e covering the outside of the cylindrical yoke 20b. Only in the axial direction region of the frame 20d where the cylindrical yoke 20b exists, the frame 20d is formed by an aluminum frame 20d, and the axial direction both end portions are formed by a resin cap 20e.

Abstract: Disclosed is a therapeutic autologous-cell delivery support system 100, in which a therapeutic autologous cell extracted from a member is reserved in reserve means 34, and an autologous-cell delivery request from the member which includes ID information and positional information is received. Membership information is retrieved in accordance with the received ID information, and the membership information and positional information of the member is output. When the reserve means is provided in plural number at geographically different locations, one reserve means having a shortest delivery time is selected in accordance with the positional information included in the delivery request. The delivery request can be issued using ID information storage means 11 for transmitting the ID information, in a simple operation, or automatically issued using a monitor of physical data.
