1. A method of securely sharing sensitive information of a first entity with a second entity such that the second entity has useable control of the sensitive information, the method comprising:

  • receiving, at a user input of a first computing device, input of sensitive information;

    transmitting the input sensitive information directly from the user input to a secure element of the first computing device;

    securing the sensitive information within the secure element by at least one of encoding and encrypting the sensitive information with an encryption algorithm and key;

    encapsulating the secure sensitive information in at least one Internet Protocol packet for transmission across a public network;

    transmitting the at least one Internet Protocol packet containing the secure sensitive information from the first entity to the second entity over a packet-switched network, wherein the first entity controls the first computing device and wherein the at least one Internet Protocol packet is transmitted from the first computing device to a second computing device controlled by the second entity;

    receiving, at the second computing device, the at least one Internet Protocol packet;

    using, by the second entity, the second computing device to un-encapsulate the secure sensitive information;

    unsecuring, within a secure element of the second computing device, the secure sensitive information; and

    using, by the second entity, the unsecure sensitive information in at least one application not controlled by the first entity.
