1. A computer-implemented method for storing and transmitting sensitive data across a computer network to one or more destinations, the method comprising: loading a removable operating system of a trusted platform to run on memory of a computing device, the computing device including a native operating system, a central processor, and a communications interface that connects the computing device to a computer network; pairing a secondary device connected to the computing device with the trusted platform; receiving input data, via the trusted platform, at a secure data storage of the secondary device unilaterally from the computing device via an one-way communication link connecting the computing device and the secondary device; storing the input data as source data wherein the input data, after input into the secondary device, is no longer retrievable from the secure data storage of the secondary device; receiving, via the trusted platform, one or more of routing, scheduling, and prioritization information for one or more destinations comprising other network-connected storage mediums or network-connected computing or peripheral devices by the secondary device; and transferring, when the secondary device is connected to the computing device, the source data from the secure data storage to the one or more destinations on the computer network through the communications interface of the computing device while bypassing the central processor and native operating system when operating under normal function of the computing device and in accordance with the one or more of routing, scheduling, and prioritization information.
