Abstract: This invention presents a method, a system, and a conversion device for wireless communications for the hosts of Human Interface Device (HID hosts), the system thereof comprises at least one host equipped with HID host as first electronic device, such as desktop computer, tablet PC, network TV and so on; at least one host equipped with HID host as second electronic device, such as cell phone, tablet PC, or other mobile devices; and at least one conversion device for wireless communication, which is externally connected to or internally embedded in, and mechanically attached to and electronically linked to the first electronic device, reports that the first electronic device being equipped HID and enables the second electronic device converted to a HID via the conversion device for wireless communication, thereby communicates wirelessly with the first electronic device, and further controls or performs input function to the first electronic device.

Abstract: A Machine-Machine Authentication method and a Human-Machine Authentication method for Cloud Computing. A Smart Card IC that includes a TPM/TCM/USB key function module and a storage memory, and a bio-feature identification method are used to achieve the Machine-Machine Authentication and Human-Machine Authentication. The Machine-Machine Authentication uses the Smart Card IC to achieve an authentication between the Server and the Client, and the Human-Machine Authentication uses the bio-feature identification method to achieve an authentication between the user and the Client or the user and the Server.
