Disclosed herein are systems and methods for determining learned associations between authentication credentials and network contextual data, such as may be utilized in a network that supports network roving. A mobile device attempts to rove to a visited network using authentication credentials associated with another network, based at least in part on first contextual information associated with the other network and second contextual information associated with the visited network indicating that the visited network is part of a common association of networks that supports roving internetworking between the networks of the common association.

Techniques described herein include a platform and process for provisioning user information onto a machine-to-machine device in order to enable the machine-to-machine device to conduct transactions utilizing the user information. In some embodiments, a user device is used to relay information between a machine-to-machine device and a provisioning service provider computer. In some embodiments, a machine-to-machine device is connected to the provisioning service provider computer via a network connection. Upon receiving a request to provision the machine-to-machine device, the service provider computer may identify the device from a device identifier. The service provider computer may generate an access credential or token for the machine-to-machine device. The access credential, token, and/or one or more policies may be provisioned onto the machine-to-machine device.

A method, system and computer program product assess risk of an unauthorized API login and mitigate damage from an unauthorized API login. The method includes collecting in a database license attributes of a user license, user profile attributes, and database content change attributes; receiving an API login request; comparing features of the API login request to at least one of the database license attributes, user profile attributes, and database content change attributes against a predetermined threshold; assessing a risk of the an unauthorized API login request based on a result of the comparison; and based on a level of the assessed risk, implemented protective action to mitigate harm that may result from an unauthorized user from accessing information or services from a computer system by way of an API.

Methods, systems, and apparatus, including computer programs encoded on computer storage media for data security protection are provided. One of the methods includes: receiving a job associated with a project, wherein the project is associated with one or more data sources; identifying a plurality of inputs and a plurality of outputs associated with the job; determining a plurality of required permissions associated with the job, wherein each of the required permissions comprises an operation on a required data source, the operation corresponding to at least one of the inputs or the outputs; verifying that the one or more data sources associated with the project comprise the required data source associated with each of the required permissions; and generating a token associated with the job, the token encoding the required permissions associated with the job, wherein the token is required for execution of the job.

One or more embodiments of the disclosure provide systems and methods for providing media presentations to users of a media presentation system. A media presentation generally includes a plurality of media segments provided by multiple users of the media presentation system. In one or more embodiments, a user of the media presentation system may share a media presentation with a co-user. The media presentation system can provide a number of features to assist a user in sharing, filtering, and accessing media presentations.

A method and device for processing one or more audio streams based on password-based privacy restrictions is described. A device may be configured to receive unrestricted audio streams of the one or more audio streams based on privacy restrictions associated with a password, wherein the one or more audio streams are from audio elements represented in an acoustic environment that comprises one or more sub-acoustic spaces, each of the one or more audio streams representative of a respective soundfield, and generate the respective soundfields of the unrestricted audio streams.

A method and processing system for managing user access to one or more resources is disclosed. A central service may receive an access change request message regarding a user. The access change request message may include a user identifier, a user role, and an access action for the user. Example access actions may include adding or removing user access with respect to a resource. The central service may determine which resources are associated with the user role and transmit one or more event messages to the resources to implement the access actions. The resources may send acknowledgement messages to the central service to confirm that the access actions have been completed.

In a method of group control and management among electronic devices, wherein the electronic devices is in communication with a control device, a projectable space instance is provided for the control device to create a workspace, wherein a control and management tool and a plurality of unified tools for driving respective electronic devices are selectively added to the projectable space instance. The projectable space instance is then parsed with a projector by the control device to automatically generate a projected workspace corresponding to the workspace to be created via the projectable space instance. The control and management tool realizes at least one status information of at least a first one of the electronic devices by way of the unified tools, and controls at least a second one of the electronic devices to execute at least one task corresponding to the at least one status information.

A method for activating an operational profile installed in a user device which is accessible to a radiocommunication network. The operational profile includes data which allows the user device to access the radiocommunication network. In such a method, the user device carries out a step of deactivating a current operational profile and activating a passive operational profile. The passive operational profile: prevents the user device from sending to the radiocommunication network at least one location update request and/or at least one attachment request to the radiocommunication network; and allows the user device to receive at least one radio-paging message including a unique identifier for the user device.

Disclosed are a method and a system for cross-chain data access of blockchain. According to the technical solution, an adapter is added between a service blockchain and a witness blockchain, a cross-chain initiation event and a cross-chain response event on a local service blockchain are registered to the witness blockchain by using the adapter, so as to provide query and push services of cross-chain events to other nodes on the local service blockchain, and trigger related operations on the local service blockchain according to the cross-chain events of the witness blockchain.
