AUTHENTICATION PROCESSING DEVICE FOR PERFORMING AUTHENTICATION PROCESSING

摘要

The present invention is to enable a user to input authentication information without burden, such that the user only has to memorize part of the authentication information even when inputting lengthy authentication information in order to ensure high-level security. When an operation of inputting and arranging authentication information in an information arrangement region is performed in a state where an arrangement status of a specified portion in the information arrangement region is set in advance as partial-authentication reference information in a reference authentication information memory, a CPU detects an arrangement status of the specified portion from an overall arrangement status in the information arrangement region, and performs, as partial authentication, processing of matching the detected arrangement status of the specified portion and the arrangement status of the specified portion set as the partial-authentication reference information.

主权项

1. An authentication processing device which performs authentication processing in response to an operation of inputting and arranging a predetermined number of pieces of information forming authentication information in a predetermined arrangement region, the device comprising:
a setting section which sets, as authentication reference information, an arrangement status in an arbitrarily specified portion by an information arrangement status in the predetermined arrangement region; a detecting section which detects an arrangement status of the specified portion from an overall arrangement status in the predetermined arrangement region when the operation of inputting and arranging the predetermined number of pieces of information forming the authentication information in the predetermined arrangement region is performed; and a partial authenticating section which performs processing, as partial authentication, of matching the arrangement status of the specified portion detected by the detecting section and the arrangement status of the specified portion set as the reference information by the setting section.
