The client makes an authorization start request by designating a resource identifier. An authorization server receiving the authorization start request inquires a resource sever of a resource owner of the designated resource identifier. After resolving the resource owner, the authorization server makes an authorization confirmation request to a user terminal corresponding to the resolved user identifier.

System, control method, and storage medium

A switching driver circuit may have an output stage having an output switch connected between a switching voltage node and an output node. A switch network may control a switching voltage at the switching voltage node so that in one mode the switching voltage node is coupled to a positive voltage and in another mode the switching voltage node is coupled to ground voltage via a first switching path of the switch network. The circuit may also include an n-well switching block operable to, when the first switching voltage node is coupled to a positive voltage, connect the n-well of the first output switch to the switching voltage node, and, when the first switching voltage node is coupled to the ground voltage, connect the n-well of the first output switch to a first ground which is separate to the first switching voltage node and independent of the first switching path.

An access control system is provided and includes a confirmation unit configured to confirm whether a region of a resource server is included in a signed access token by comparing a region included in the signed access token and the region of the resource server, and executes processing with respect to a resource request in a case where a determination unit determines that the signed access token is valid and the confirmation unit confirms that the region of the resource server is included in the signed access token.

A per-resource user authority management unit that manages user authorities per resource, a user authority refinement unit that refines authorities linked to a user by the per-resource user authorities, and an authority verification unit that determines whether execution of processing with respect to a resource is permitted by using an authority that has been refined by the user authority refinement unit are provided.

This application relates to audio circuits, such as audio driving circuits, with improved audio performance. An audio arrangement () has an audio circuit () with a forward signal path between an input () for an input digital audio signal (D) and an output () for an output analogue audio signal (A). The circuit also has a feedback path comprising an analogue-to-digital conversion module () for receiving an analogue feedback signal (V) derived from the output analogue audio signal and outputting a corresponding digital feedback signal (D). The analogue-to-digital conversion module () has an ADC (), an analogue gain element () configured to apply analogue gain (G) to the analogue feedback signal before the ADC and a digital gain element () for applying digital gain (G) to a signal output from the ADC. A gain controller () controls the analogue gain and the digital gain applied based on the input digital audio signal (D).

When a request for analysis target data is received from a web server, a classification designated by the request is identified, and whether the web server is permitted to access the analysis target data that corresponds to the identified classification is checked.

Data management system, control method, and storage medium

An authentication server system issues a first-type token for verification of whether a user operating a terminal is a valid user and a second-type token for verification of whether a service is usable with authority transferred to an authorized client cooperating with the service, verifies, based on a token received with a verification request and a scope regardless of a type of the issued token, and notifies a verification result.

Authentication server system, method, and storage medium

There is provided an authority delegation system capable of issuing, in a case where an identifier of a user is associated with an identifier of a client, authority information indicating that an authority of the user has been delegated to the client without receiving an instruction for authorizing the authority of the user on the service to be delegated to the client.

An authority transfer system enables omitting authorization of a user belonging to a tenant based on an authorization operation being performed at least once on a terminal associated with the tenant.

Authority transfer system, method that is executed by authority transfer system, and storage medium

In response to reception of a request, an authorization server system identifies authorization based on first authorization information received by a reception unit along with the request. The authorization server system gives at least some of the identified authorization to an application, and issues second authorization information for identifying the given authorization.

Authorization server system, control method thereof, and storage medium

A second information processing system to communicate with a first information processing system includes an acquisition unit, an acceptance unit, a confirmation unit, and a setting unit. The acquisition unit acquires authentication information from the first information processing system and from a memory of the second information processing system. The acceptance unit accepts correspondence information indicating correspondence between first authentication information and second authentication information. The confirmation unit confirms, as a condition, whether the acquired authentication information in the first information processing system is identical to the accepted first authentication information and confirms, as a condition, whether the acquired authentication information in the second information processing system is identical to the accepted second authentication information. The setting unit does not set the correspondence information as single sign-on setting information if a condition is not satisfied and sets the correspondence information as single sign-on setting information if both conditions are satisfied.

Information processing system, control method for controlling the information processing system, and storage medium

An authority delegate system including a first server system to manage specific information, a second server system to provide a service, an authentication device, and a client operated by a first user who is authorized to use the service, includes a reception unit, a transmission unit, a management unit, a determination unit, and a provision unit. The reception unit receives an authorization token shared range for authorizing specific information usage. The transmission unit transmits to the client a setting screen for setting whether to permit users within the shared range to share the authorization token. The management unit manages the setting screen set shared range, and the authorization token issued by the authentication device. The provision unit provides, in response to determining that the second user is included in the shared range and confirmation that the authorization token is valid, the service to the second user using the specific information.

Authority delegate system, server system in authority delegate system, and control method for controlling authority delegate system

An information processing system stores key information for determining an authentication device and information about the authentication device by associating these information pieces with each other and extract the key information from access of an unauthenticated user. Based on the information about the authentication device associated with the key information, the access of the unauthenticated user is redirected.

Information processing system, method for controlling information processing system, and storage medium

An authentication apparatus receives an authority delegating request from an apparatus, acquires information of authorities possessed by the user from a storage unit, presents information of the acquired authorities to the user, and receives an instruction indicating which of the authorities possessed by the user is delegated to the apparatus. A storage unit stores, when the instruction to delegate the authority to the apparatus is received, an identifier required to uniquely identify the instruction and the authority instructed by the user to delegate, in association with each other. Authentication information indicating delegation of the authority is transmitted to the apparatus based on the instruction from the user.
