20090077002 | KNOWLEDGE BASED SYNCHRONIZATION OF SUBSETS OF DATA WITH NO MOVE CONDITION - An efficient way is provided to represent and exchange knowledge and/or partial knowledge across nodes when synchronizing between any two nodes. A first node sends a second node its knowledge and/or partial knowledge, including objects and versions of those objects. The second node compares its knowledge and/or partial knowledge with the knowledge and/or partial knowledge of the first node, and then sends the first node any latest versions of objects of which the first node is unaware. In addition, the second node sends its knowledge and/or partial knowledge to the first node. The first node then performs a similar object-by-object version comparison to determine any conflicts due to independent evolution of objects and any changes that should be sent to the second node in order to bring the objects of the second node up to date with the knowledge and/or partial knowledge of the first node. | 03-19-2009 |
20090083210 | EXCHANGE OF SYNCRONIZATION DATA AND METADATA - Systems and methods that disclose alternative patterns for exchange of synchronization data and/or metadata, e.g., ‘knowledge’, to enhance performance of synchronization processes are disclosed. Accordingly, the innovation discloses synchronization mechanisms that employ exchange of data and metadata to alleviate a requirement of a complete ‘round-trip’ when synchronizing data. ‘Knowledge’ can be provided which informs a provider of data changes, modifications, additions or deletions. The ‘knowledge’ can lower expense and/or increase efficiencies of the synchronization exchanges by enabling informed decision-making related to enumerating changes within the synchronization processes. | 03-26-2009 |
20090083441 | SYNCHRONIZATION OF WEB SERVICE ENDPOINTS IN A MULTI-MASTER SYNCHRONIZATION ENVIRONMENT - A Web service synchronization protocol is provided that sets forth the metadata and messaging by which endpoints roam, share and synchronize common information with one another in a multi-master networked computing ecosystem. A general SOAP-based protocol is defined for synchronizing data between two endpoints where one or more of the endpoints supports a Web service. Defining messaging for knowledge-based transfers using XML Web services, the protocol allows devices, services and applications to synchronize through firewalls, allows for flexibility by allowing any common set or subset of information across endpoints and allows for extensibility by not prescribing the schema of the actual data being synchronized at the endpoints. | 03-26-2009 |
20090196179 | REPRESENTATION OF QUALITATIVE OBJECT CHANGES IN A KNOWLEDGE BASED FRAMEWORK FOR A MULTI-MASTER SYNCHRONIZATION ENVIRONMENT - The subject disclosure relates to synchronizing among network nodes in a multi-master synchronization environment that extend a knowledge based synchronization framework to include notions of object quality. In one embodiment, additional dimension(s) are placed on a knowledge vector for a given version of an object that represent quality information for the object, which is accounted for during the synchronization process to allow nodes to decide what types of qualities of objects should be conveyed to them as part of the synchronization process. Other embodiments include tombstoning objects to avoid future synchronization with respect to same objects maintained by other nodes in the multi-master synchronization environment. Advantageously, according to the synchronization framework, endpoints can synchronize data in a way that allows a definition and consideration of quality of one or more objects of the synchronized data for purposes of a knowledge exchange. | 08-06-2009 |
20100057785 | MINIMAL EXTENSIONS REQUIRED FOR MULTI-MASTER OFFLINE AND COLLABORATION FOR DEVICES AND WEB SERVICES - The claimed subject matter provides a system and/or a method that facilitates managing data consistency in connection with a plurality of devices. A collection of devices can be associated with a user. A web service can receive a portion of data from at least one device via an interface component, wherein the web service can host and relate the portion of data with an account for the user. A master sync component can leverage a computing resource from at least one device in order to maintain data consistency between at least one of the following: two or more devices within the collection of devices associated with the user; or the account hosted by the web service and two or more devices within the collection of devices associated with the user. | 03-04-2010 |
20100100527 | FORGETTING ITEMS WITH KNOWLEDGE BASED SYNCHRONIZATION - Systems and methods that enable removal of data from an endpoint, while not propagating such removal to other endpoints when synchronizing data sources associated therewith. A designation component can indicate items as forgotten items, wherein such items are being known to an endpoint and deleted therefrom—yet, reintroduced therein and reappearing (e.g., as a create) upon re-synchronizing with the replica over again. Moreover, the forgotten items can employ additional metadata such as in from of an additional bit that indicates whether an item is a forgotten item. | 04-22-2010 |

20140075184 | TRUST SERVICES FOR SECURING DATA IN THE CLOUD - Embodiments are directed to securing data in the cloud, securely encrypting data that is to be stored in the cloud and to securely decrypting data accessed from the cloud. In one scenario, an instantiated trust service receives information indicating that a trust server is to be instantiated. The trust service instantiates the trust server, which is configured to store key references and encrypted keys. The trust service receives the public key portion of a digital certificate for each publisher and subscriber that is to have access to various specified portions of encrypted data. A data access policy is then defined that specifies which encrypted data portions can be accessed by which subscribers. | 03-13-2014 |
