Abstract: A virtual data store system comprises a network interface and a processing device operable to access a source database of data records comprising data, wherein an entity is enabled to utilize the virtual data store system as a database. A verification query is formulated with respect to a data record, that stores an item of data, which is transmitted to online network sources via a proxy service. A query response is parsed and in response to determining that the item of data in the data record is potentially present in the parsed response, a corresponding confidence score is generated. If the confidence score is below a first threshold, a subsequent verification operation is performed. If the subsequent verification operation fails, the second item of data is deleted from memory to conserve memory resources. The data record may be accessed from the virtual data store and used to initiate a networked communication.

Abstract: A method of data recovery for a distributed storage system is a method of recovering multiple failed nodes concurrently with the minimum feasible bandwidth when failed nodes exist in a distributed storage system. By means of selecting assistant nodes, obtaining helper data sub-blocks through computing the selected assistant nodes, then computing a repair matrix and finally multiple the repair matrix and the helper data sub-blocks, the missing data blocks are reconstructed; or the missing data blocks are reconstructed by decoding. The method is applicable to data recovery in the case of any number of failed nodes and any reasonable combinations of coding parameters. The data recovery herein can reach the theoretical lower limit of the minimum recovery bandwidth.
