Abstract: Disclosed are system and method for verification of data transferred among several data storages. An exemplary method includes: calculating first hash-sums of the data during an initial placement in a data storage; transmitting the first hash-sums to at least one blockchain network; detecting a transfer of the data to a new data storage; calculating second hash-sums of the data after a placement of the data in the new data storage; transmitting the second hash-sums to the at least one blockchain network; comparing the first and second hash-sums of the data; and determining data immutability after the transfer of the data from the data storage to the new data storage based at least on results of the comparing.

Abstract: A system and method provided for managing services and licenses using blockchain technology. An exemplary method includes storing an operator license relating to an operator node associated with a vendor, where the operator license indicates transactional authority of the operator node. Moreover, the method includes executing a transaction relating to a service and/or a license provided to client device; transmitting data relating to the operator license to a blockchain network in which a node in the blockchain network adds the data relating to the operator license as one or more blocks in an existing blockchain; and replicating the transaction to at least one additional node in the blockchain network. As a result, the existing blockchain can be used to verify the transaction authority of the operator node and the transaction between the client device and the operator node.

Abstract: A system and method is provided for storing data and ensuring integrity and reliability of the data using blockchain technology. An exemplary method is provided for time-stamping a file to be added to a blockchain network. The method includes generating a data file; identifying a hash value from a first block previously recorded in the blockchain network; embedding a beacon relating to the hash value in the data file; and recording the data file with the embedded beacon as a transaction in a second block in the blockchain network.

Abstract: Disclosed are blockchain-based methods and systems for watermarking digital content. In an exemplary aspect, a method for watermarking digital content is provided, by receiving, by a processor, a data stream comprising audio and/or video content; receiving watermark data, by a processor, from a computing node communicatively linked to a blockchain-based distributed ledger; and applying at least one watermark to the data stream based upon the watermark data, wherein the watermark comprises at least one hash based on one or more data blocks stored in the blockchain-based distributed ledger.

Abstract: A system and method for authenticating data files using a block chain network. An exemplary method includes identifying data files in electronic data storage, computing hash values for files, adding pairs of the hash values and computing hash values for each resulting pair, continuing this process to a root level of a hash tree, and sending the root hash to a blockchain network in which one or more nodes in the blockchain network adds the hash value as one or more blocks in a blockchain.

Abstract: A system and method provided for verifying data integrity for large volumes of critical data using blockchain technology. An exemplary method includes storing data files in electronic storage; creating a hash values for of each of the files; and transmitting the hash values to a blockchain network in which one or more nodes in the blockchain network adds the first hash values as blocks to the blockchain. Moreover, an API is provided to monitor data operations performed on the data files and transmit metadata of any operations performed to a transaction log. In turn, hash values relating to the data operations are also created and transmitted to the blockchain network to be added as additional blocks in the blockchain, such that the blockchain can be used to verify the accuracy of the data files stored on the electronic storage.
