  • Publication number: 20230362158
    Abstract: In a mechanism in which an information processing apparatus that executes an application for controlling authentication processing using an external authenticator worn by a user transmits signature data received in a case where the authentication using the external authenticator is successful to a system and the signature data is verified, the external authenticator provides a notification to the user in response to at least one of a result of the authentication by the external authenticator and a request transmitted from the information processing apparatus to the external authenticator.

  • Patent number: 11135776
    Abstract: A management system at least has a management server configured to manage information regarding a control device configured to execute a job for molding, by using a material, a three-dimensional object including an object corresponding to three-dimensional model data to be molded. The management system generates execution history of a job including a result of molding received from the control device and a control command used for the molding, collects the generated execution history of the job, and totalize a used amount (or usage) of a material used for molding the molded object including the object based on the collected execution history. The management system totalizes usages of the material used for a non-object for execution of the job.

  • Publication number: 20210158213
    Abstract: A learning model management system executes a provisional evaluation when the number of feedback data is equal to or less than a threshold of a definite evaluation but is more than a threshold of a provisional evaluation. In this provisional evaluation, prediction accuracy of the learning model that is in operation is evaluated a plurality of times, and whether or not the prediction accuracy of the learning model that is in operation is in a deterioration trend is determined based on the change tendency of the evaluation results. If it is determined that the prediction accuracy of the learning model that is in operation is in a deterioration trend, the learning model management system provides a notification about the deterioration trend of the prediction accuracy to a manager to cause him/her to increase the number of feedback data up to a number that enables the definite evaluation.

  • Patent number: 10992838
    Abstract: An MFP stores a plurality of different pieces of biometric information of a user and a plurality of secret keys respectively corresponding to the pieces of biometric information in the TPM and registers public keys corresponding to the private keys in a server. When an authentication request is received from the server, the MFP executes a biometric authentication process using the biometric information input from the user and the biometric information registered in the TPM. If authentication is successful in the biometric authentication process, the MFP creates signature data and transmits it to the server. If verification of the signature data using the public key in the server is successful, the MFP performs display related to a shortcut process associates with the biometric information corresponding to the secret key used when the signature data that is a target of the verification is created by an input and output device.

  • Patent number: 10853477
    Abstract: A portable terminal has an authenticator for biometric authentication, and a TPM for storing biometric information of a user necessary when performing authentication processing with the authenticator and a secret key generated for the biometric information. At the time of initialization of an OS, the portable terminal transmits a request for a registration cancelation using a registration cancelation URL to a server in which registration information including a public key which is a pair with a secret key is registered. When an authentication request for the registration cancelation is received from the server, a signature is generated using the secret key extracted according to an authentication success in the biometric authentication of the authenticator using the biometric information read by the biometric information sensor, when the signature is successfully verified by being transmitted to the server, the registration cancelation of the registration information is performed in the server.

  • Publication number: 20180150336
    Abstract: Management systems and control methods are provided herein. A management system determines a virtual machine to which a request is transferred from a load sharing apparatus. The management system transfers the request from a load sharing apparatus in a first processing environment to a virtual machine in a second processing environment when a setting of an apparatus which receives the request from the client is switched from the load sharing apparatus in the first processing environment to a load sharing apparatus in the second processing environment, and does not transfer the request from the load sharing apparatus in the first processing environment to a virtual machine in the first processing environment.
