Through a cloud-based centralized user interface, a federated compliance system presents a policy of interest and representations of disparate systems that match the policy of interest to a user. The disparate systems, which operate in a distributed network computing environment, can include cloud-based repositories and off-cloud repositories. The federated compliance system can pull the cloud-based repositories through a cloud orchestrator and the off-cloud repositories through an off-cloud orchestrator over a secure tunnel. The federated compliance system utilizes user-provided information on the policy of interest to determine various categories of attributes from different repository schemas employed by the disparate systems. A federated retention policy mapper, implemented as a compliance service, maps the attributes to a common schema, creates a federated retention policy, and stores it in a federated space in the distributed network computing environment. A policy change can be automatically propagated across the disparate systems using the federated retention policy.

Disclosed herein are systems and methods for synchronizing anonymized linked data across multiple queues for SMPC. The systems and methods guarantee that data is kept private from a plurality of nodes, yet can still be synced within a local queue, across the plurality of local queues. In conventional SMPC frameworks, specialised data known as offline data is required to perform key operations, such as multiplication or comparisons. The generation of this offline data is computationally intensive, and thus adds significant overhead to any secure function. The disclosed system and methods aid in the operation of generating and storing offline data before it is required. Furthermore, the disclosed system and methods can help start functions across multi-parties, preventing concurrency issues, and align secure input data to prevent corruption.

Systems and methods are described for backing up confidential data using user devices on the same local network. In an example, a first user device can download a data file from a server. The first user device can connect to the server on the same local network as a second user device. A user can select to delete the file from the first user device. The first user device can send the data file to the second user device using a local Internet Protocol (“IP”) address of the second user device. The second user device can store the data file on its local storage. If the user chooses to retrieve the data file to the first user device again, and if the user devices are on the same local network, the first user device can retrieve the data file from the second user device instead of the server.

In some examples, a method includes receiving a personalization setting from a first agent on a first device. In some examples, the first device provides a local operating environment. In some examples, the method includes sending the personalization setting to a second agent on a second device that provides a virtualized operating environment, to coordinate a behavior or appearance of the virtualized operating environment with a personalized behavior or appearance of the local operating environment.

Networking systems and methods for establishing and maintaining virtual computing clouds are disclosed. A networking system can comprise a server and various instances of a software agent, each agent being installed on a computing device participating in a virtual computing cloud. The server can maintain account setting for a user, wherein the settings can indicate which files on indicated computing devices are included in the virtual computing cloud. The networking system can selectively synchronize data between the computing devices automatically and in a secure manner, and can transmit data in real time to simulate local storage when synchronization of certain files is inappropriate in light of file incompatibility. As a result, the networking system can provide the user with a seamless, automatic system and method for accessing a total computing environment.

Determining active membership among a set of storage systems, including: determining, by a cloud-based storage system among the set of storage systems, that a membership event corresponds to a change in membership to the set of storage systems synchronously replicating the dataset; applying, in dependence upon the membership event, one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset; and for one or more I/O operations directed to the dataset, applying the one or more I/O operations to the dataset synchronously replicated by the new set of storage systems.

In a multi-source hybrid overlay network including a plurality of peers, an apparatus that recovers missing data occurring in a tree recovery process, acquires data that a peer does not have in a pull method through exchanging buffer maps with a first counterpart peer connected to a primary path recovered in the tree recovery process and at least one second counterpart peer connected to at least one candidate path, and provides data that the first counterpart peer does not have to the first counterpart peer in the push method, when a data recovery policy is a pull method, is provided.

Various embodiments herein described are directed to methods, apparatuses and computer program products configured for improving data synchronization in on-premises application service systems. In some embodiments, an on-premises application service system may transmit a synchronization check message to an in-cloud application service system and receive a synchronization request message in response. Based at least in part on the synchronization request message, the on-premises application service system transmits data objects to the in-cloud application service system for synchronization. Additional example embodiments provide various example methods of managing synchronizations between on-premises application service systems and in-cloud application service systems that improve data security and reduce network traffic.
