## Abstract

A method includes obtaining, by a secure data conveyance device of a data communication system, information pertaining to a data conveyance between a user computing device and a target computing entity. The data conveyance involves the user computing device providing data in a first format and the target computing entity accepting data in a second format. The information includes an amount of the data in the first format. The secure data conveyance device stores the data in the first format on behalf of the user computing device. The method further includes converting the amount of the data in the first format to an amount of data in the second format via a secure data conversion process where the amount of data in the second format is only usable by the target computing entity, and providing the amount of data in the second format to the user computing device.
