Abstract: Techniques described herein relate to a method for managing transactions in a distributed ledger. The method includes obtaining a transaction request from a client; in response to obtaining the transaction request: verifying client information associated with the client and the transaction request; anonymizing the transaction request to generate an anonymous transaction request; updating client payload mappings based on the anonymous transaction request; shuffling the anonymous transaction request with a batch of requests to generate a shuffle index; assigning the batch of requests to virtual users to generate virtual user assignments; and processing the transaction request using the batch of requests.

Abstract: A method for providing a coresident copy of external container data, that includes identifying, via a cluster storage manager, an access request to a cluster storage for external container data, where the access request is sent from a container executing on a first host, making a determination that the external container data is not stored on the first host, and based on the determination, copying the external container data from a second host to the first host to provide the coresident copy of the external container data.

Abstract: A fragment and shuffle erasure coding operation is disclosed. In a transformative operation, encrypted fragments are generated from an input file. The transformative operation includes one or more iterations of chunking the file and mixing the chunks to generate a mixed sequence. The mixed sequence is sliced into encrypted fragments. The encrypted fragments are shuffled in a storage system such that physical locations of the encrypted fragments change over time.

Abstract: Techniques are provided for securing data storage by slicing swapped data portions into data fragments and shuffling a physical storage location of the data fragments. One method comprises obtaining at least one data item; dividing the at least one data item into a plurality of data portions; swapping respective positions of at least two of the data portions of the at least one data item; slicing the plurality of data portions, following the swapping, into a plurality of data fragments; and shuffling a distribution of the data fragments across a plurality of storage nodes in a storage system by moving at least one data fragment from a current physical storage location on a current storage node to a different physical storage location on a different storage node. A predefined number of the plurality of data fragments may be needed to reconstruct the data item.

Abstract: A multiphase vortex flowmeter system determines the gas-to-liquid ratio (GLR) and flow rates from a well producing multiphase gas, oil and water by detecting the frequency and amplitude of vortices shed in a vortex flowmeter. In particular, the phase of the flow can be identified by detecting the change in the frequency of the vortices with respect to time, and the amplitude of the vortices. Based on the phase, the flow rates of liquid and gas can be calculated. As a feedback technique, these calculated values can be “tuned” by comparison with actual GLR and flow rates recorded for the well by a test separator.

Abstract: A method includes receiving, at a content provisioning system from one or more client devices, one or more requests for file digests stored in respective data stores of a plurality of data stores in a distributed file system. The file digests are distributed across different ones of the plurality of data stores in the distributed file system. The method also includes determining a location of a given one of the requested file digests in one or more of the plurality of data stores and retrieving the given file digest from the determined location. The method further includes shuffling the distribution of the file digests across the plurality of data stores in the distributed file system.

Abstract: A DC voltage distribution system includes at least one load connected in parallel to a first DC power supply via a first distance of wire, and connected in parallel to a second DC power supply via a second distance of wire. The first and second DC power supplies are configured to enter a load sharing mode in which one of the first or second DC power supplies selectively increases its voltage to prevent the other of the first or second DC power supplies from exceeding its power output threshold. The DC power supplies are also configured to enter a load balancing mode in which the DC power supplies set their output voltages to the same value such that a flow of current on the longer of the wire distances is reduced and a flow of current on the shorter of the wire distances is increased.
