Quantum computers with a limited number of input qubits are used to perform machine learning processes having a far greater number of trainable features. A list of features of a field are divided into a plurality of feature groups. Each of the feature groups includes a respective group of some, but not all, of the features. A first machine learning process is performed to train a first instance of a quantum computer model, where the feature groups are used as inputs. Based on the first machine learning process being performed, a subset of the feature groups is selected for a second machine learning process. Thereafter, the second machine learning process is performed to train one or more second instances of the quantum computer model. The individual features of the selected subset of the feature groups are used as inputs for the second instances of the quantum computer model.

Methods and systems are presented for providing a framework for facilitating multi-party computation within a sharding environment. After a blockchain is divided into multiple shard chains, a multi-party computation system obtains attributes associated with a first shard chain. The attributes may represent characteristics of the first shard chain, characteristics of transactions recorded in the first shard chain, and characteristics of the computer nodes configured to manage the first shard chain. Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain. The multi-party computation system configures the computer nodes configured to manage the first shard chain to perform the transaction validation process according to the multi-party computation scheme.

Methods and systems are presented for providing a multi-party computation (MPC) framework for dynamically configuring, deploying, and utilizing an MPC system for performing distributed computations. Based on device attributes and network attributes associated with computer nodes that are available to be part of the MPC system, a configuration for the MPC system is determined. The configuration may specify a total number of computer nodes within the MPC system, a minimum number of computer nodes required to participate in performing a computation process, a key distribution mechanism, and a computation processing mechanism. Encryption keys are generated and distributed among the computer nodes based on the key distribution mechanism. Upon receiving a request for performing the computation, updated network attributes are obtained. The configuration of the MPC system is dynamically modified based on the updated network attributes, and the MPC system performs the computations according to the modified configuration.

Methods and systems are presented for providing a secured framework for facilitating electronic transactions using a multi-party computation approach. Under the multi-party computation approach, the task of authenticating a transaction conducted through a user account is distributed among multiple computer nodes. One or more secrets and shares of a secret are distributed among the multiple computer nodes. An authentication process is implemented such that at least a portion of the multiple computer nodes, including one or more required nodes, exceeding a predetermined number of nodes are needed to perform a set of computations using the corresponding secret(s) and/or shares of the secret in order to generate a digital signature for the user account. By verifying the digital signature using a public key of the user account, it can be determined that the participation requirement has been satisfied.

Systems and methods for encrypting and decrypting a data encryption key are provided. A data encryption key used to encrypt data is encrypted using a first asymmetric key and a policy. The policy includes rules that correspond to attributes. A second asymmetric key is associated with the attributes. To decrypt the encrypted data encryption key, the attributes are used to identify the second asymmetric key. The attributes are also used to pass the rules in the policy included in the encrypted data encryption key. If the attributes pass the rules in the policy, the encrypted data encryption key is decrypted. The decrypted data encryption key can then decrypt the encrypted data.

Attribute-based key management system

Methods and systems for providing fast random access and/or inspection of records within an encrypted communication session are presented. The encrypted communication session may include encrypted records that were encrypted using rotating encryption keys. A key index is generated for the encrypted communication session. The key index includes the encryption keys used during the encrypted communication session and timestamps associated with the encryption keys. To access a particular record within the encrypted communication session, a particular encryption key is selected from the encryption keys stored in the key index. The particular record is decrypted using the selected encryption key.

A cache management system, method, and computer-readable medium which manage caching of resources are provided. The method includes receiving a request for a resource including a hierarchical resource locator, fetching the resource from a node upon determining that the resource is not stored in a cache, adding an entry for the resource to a mapping table associated with the cache, the entry including the resource locator and dependency information for dependent resources identified from the hierarchical structure of the resource locator, and updating entries in the mapping table for master resources identified from the hierarchical structure of the resource locator, the updated entries including an identifier for the resource.

A cache management apparatus, method, and computer readable medium which manages caching of resources. The method includes analyzing a structure of a resource in a system which exposes resources to clients, generating a dependency graph of objects linked to a resource based on the analyzed structure of the resource, and managing caching of resources based on the generated dependency graphs. A generated dependency graph includes hierarchical dependency information with respect to the objects of the resource.

A system for media content selection. In one embodiment, a home entertainment system for accessing content includes a processor for executing instructions adapted for: (i) receiving a request from a user input for selecting a content title; (ii) displaying formats of the content title, with one format stored in a home network and another stored external to the home network; (iii) receiving a request from the user input device to select one of the formats; and (iv) presenting the selected content in the selected format. The content can be a song in a digital format, for example. Selecting the content can include consideration of user preference information and using one or more of: a content manager, a device manager, a network controller, a purchase controller, a device supporter, a content directory, a connection manager, and a digital rights management (DRM) controller. The user input device can include, for example, a remote control device for a home entertainment system.

A broadcast of an event is enhanced with synthetic scenes generated from audio visual and supplemental data received in the broadcast. A synthetic scene is integrated into the broadcast in accordance with a depth map that contains depth information for the synthetic scene. The supplemental data may be sensing data from various sensors placed at the event, position and orientation data of particular objects at the event, or environmental data on conditions at the event. The supplemental data may also be camera tracking data from a camera that is used to generate a virtual camera and viewpoints for the synthetic scene.
