Electronic device and authentication method therein

摘要

Provided is an electronic device and an authentication method able to restrict and disable an operation when a third person other than an authorized user who is registered as a user, and prevent information leakage without requiring the user a complicated operation. At a time when an operator inputs an authentication request by any one of the user identification numbers, when first information inputted via the input part is coincided with the first password related to the user identification number for which the authentication request is inputted, and when characteristic data at a time when the first information is inputted falls within a specified range of a histogram of the databases related to the user identification number for which the authentication request is inputted, the operator is authenticated as the user for which the authentication request is inputted.

主权项

1. An authentication method implemented in an electronic device, the electronic device including:
an input part that is configured for an operator to input various pieces of information, the operator being each of one or more users, and a storage part that is configured to store a respective piece of information of each of the one or more users, the method comprising: causing the storage part to hold a respective piece of information of each of the one or more users, the respective piece of information being in the form of a mutually related set of a user identification number for each of the one or more users, a first password for each of the one or more users, and a database that is configured to store various pieces of characteristic data that are involved in at least an inputting of the first password via the input part that is conducted by each of the one or more users; and authenticating an operator as a user who is related to the user identification number that is inputted at a time of the authentication request in a case where the operator conducts an input for requesting an authentication relied on any one of the user identification numbers that are stored in the storage part, when a first piece of information that is inputted via the input part is in coincidence with the first password that is related to the user identification number of the inputted authentication request and concurrently when each of the various pieces of information at a time of inputting the first information via the input part falls within a specified region that is set relative to a histogram that the data base indicates that is related to the user identification number of the inputted authentication.
