A method processes an input image securely. In order to identify an object, a reading device obtains a first and a second signal from the first and second sets of identification information of the object respectively, determines the relative spatial position between the two sets of information, and determines the signature of the object. By depositing the dielectric layers in vacuum, very thin layers are possible, which yields increased transparency and electrical capacitance. The first, second, third, and fourth transmit symbols are transmitted based on first and second resource indexes. The second policy server generates an encryption key. 25% to 3% by weight of silica and the like, particularly fumed silica, to the cathodes of the cells and particularly to cathodes comprised of lithiated metal oxide.
