Systems and methods for document search and aggregation with reduced bandwidth and storage demand

A system comprising,

• a local network, including a local content repository and a local processing device;
• a cloud service, including a cloud content repository and a cloud processing device;
• a communicative coupling between the local network and the cloud service, wherein communication between the local network and the cloud service is always one-way from the local network to the cloud service;
• wherein the local content repository includes computer-readable instructions stored in non-transitory memory for:
• in response to a search request comprising a keyword, reducing a bandwidth demand on the communicative coupling by searching in the local content repository for documents which contain the keyword, deduplicating the documents which contain the keyword, deNISTing the documents which contain the keyword, and then sending the deduplicated, deNISTed documents which contain the keyword to the cloud service via the communicative coupling, generating a log file for each of the documents indicating a location and a time of the search request, and sending the log file to the cloud service via the communicative coupling, wherein deNISTing the documents includes automatically removing one or more files of the documents based on file type, and wherein the deduplicating and deNISTing are performed at the local processing device, remote from the cloud service and cloud processing device.

A method, comprising,

• for an e-discovery search,
• receiving a task command from an operator, the task command including one or more search terms specified by the operator;
• responsive to receiving the task command, collecting files matching the one or more search terms on a local content repository of a local system, deduplicating the files on the local content repository, and deNISTing the files on the local content repository;
• and
• dividing the deduplicated and deNISTed files into a content file and a metadata file for each of the deduplicated and deNISTed files, and then
• sending the content files and the metadata files to a cloud facility for storage, wherein deNISTing the files includes removing one or more of the collected files which match the one or more search terms responsive to the one or more files being a file type indicated on a NIST list,
• wherein communication between the local system and the cloud facility is always one-way from the local system to the cloud facility, and
• wherein the deduplicating and deNISTing are performed at the local system of the local content repository, remote from the cloud facility.
