Abstract: A method for writing with a DIRE (data integration and routing engine) controller may comprise receiving, by an application protocol interface (API) server, data from an end-user, and splitting, by the API server, the data in multiple ways based on directives contained in a data privacy and handling policy of a user, wherein the splitting includes using a hashing algorithm to create a key representing a document of the data. The data may be processed through the DIRE controller. For example, the DIRE controller may tag the key with geolocation information for future retrieval; the DIRE controller may route the data to a server in a geolocation based on the geolocation information; and the DIRE controller may maintain a key-value pair database that maps the key to the geolocation of the document for later retrieval. The disclosure also includes a system or method for reading with a DIRE controller.
