Abstract: In a remote authorization control system including a resource access device, a resource management device, and an authentication device, the resource access device downloads an access control list from the authentication device onto a secure region in the resource access device. The resource access device downloads resources from the resource management device onto the secure region. The resource access device determines whether a user is allowed to use the resources based on the access control list when a resource use request is received from the user, and the resources access device allows the user to use the resources when the resources are usable.

Abstract: A program execution system includes a data holding apparatus, a program providing apparatus, and a data processing apparatus that performs computing in a secure region. The data holding apparatus transmits encrypted data, encrypted with a first common key, to the data processing apparatus, and the program providing apparatus transmits an encrypted program, encrypted with a second common key, to the data processing apparatus. In the secure region, the data processing apparatus acquires data by decrypting the encrypted data with the first common key, acquires a program by decrypting the encrypted program with the second common key, executes the program for the data, and encrypts a result of the execution with a public key of the data holding apparatus or the first common key. The data holding apparatus acquires the result of the execution by decrypting the encrypted result of the execution with a secret key or the first common key.

Abstract: An authentication-control system including one or more computers, the authentication-control system includes: a registration unit that, in response to a notification of registration of a software resource after a change, registers in a storage unit a person who has made the change as a right holder of the software resource after the change, together with a right holder of the software resource before the change; an inquiry control unit that, in response to a permission request for use or editing of the software resource, controls an inquiry as to permission or rejection to right holders registered in the storage unit regarding the software resource; and a response unit that makes a response indicating permission for the permission request when permission is obtained from all the right holders. As result, it is possible to appropriately control authorization for access to a software resource changed in a distribution process.

Abstract: An action learning system includes a memory, and a processor configured to train, based on first data indicating a property of an environment in which data is collected from multiple devices and to which an action determined by a first neural network according to a state of the environment is applied and second data indicating a property of the environment to which the action is not applied, a second neural network that calculates a similarity degree between distributions of the first data and the second data, and train, after the second neural network is trained, the first neural network that determines an action according to the state of the environment, by reinforcement learning including, in a reward, a value that changes based on a relationship between a similarity degree and a parameter set by a user, the similarity degree being calculated by the second neural network based.
