Abstract: A method for processing electronic documents comprises an iteration including: (i) applying, by a computer device, a first statistical test process to a first subset of the documents, the first statistical test process estimating whether or not content of the documents of the first subset comply with a predefined criterion; (ii) in response to a result of the first statistical test process, estimating, by the computer device, that the documents of the first subset do not comply with the criterion, selecting, by the computer device, a part of the documents of the first subset, and moving, by the computer device, the part of the documents to a second subset of the documents; and (iii) applying, by the computer device, a second statistical test process to the second subset of the documents, the second statistical test process calculating at least one statistical metric related to the documents of the second subset.

Abstract: An example operation may include one or more of connecting, by a virtual blockchain manager node, to a blockchain configured to store a plurality of user transactions committed by a user node, identifying, by the virtual blockchain manager node, a user request transaction from the plurality of the user transactions for a creation of a virtual blockchain for the user, wherein the user request transaction contains a rule, creating, by the virtual blockchain manager node, the virtual blockchain based on the user request transaction, populating, by the virtual blockchain manager node, the virtual blockchain with the user transactions from the plurality of the user transactions from the blockchain based on the rule, and executing, by the virtual blockchain manager node, a smart contract to record the rule and a hash of all blocks from the virtual blockchain onto the blockchain.

Abstract: The invention relates to a computer-implemented method for performing an electronic discovery process using a blockchain. For at least two of phases of the electronic discovery process individual electronic data processing tools are used for executing the respective phase. For each of the phases of the electronic discovery process metadata of the electronic data objects subject to the respective phase of the electronic discovery process and to the electronic data processing tool used for executing the respective phase are stored in the blockchain. Furthermore, audit information about auditable actions carried out during the respective phase by the electronic data processing tool used for executing the respective phase on the electronic data objects is stored in the blockchain. The stored audit information provides an end-to-end audit trail for each of the electronic data objects subject to at least one of the phases of the electronic discovery process.
