The Export Control Act of 1949 gave the President power to prohibit or curtail the export of technical data.[489] Also pertinent is the stipulation in an August 1953 statute permitting the government to lend certain vessels to Italy, which prohibited the transmission to Italy of information, plans, advise, material, documents, blueprints, or other papers bearing a secret or top secret classification.[490] In 1951 legislation was enacted prohibiting disclosure of classified information. It is unlawful knowingly and willingly to communicate, furnish or transmit to an unauthorized person the following categories of classified information: (1) codes, cipher or the cryptographic system of the United States or any foreign government; (2) the design, construction, use, maintenance, or repair of any device, apparatus, or appliance used or prepared or planned for use by the United States or any government for cryptographic or communication intelligence purposes; (3) the communication intelligence activities of the United States or any foreign government; or (4) obtained by the processes of communication intelligence from the communications of any foreign government knowing the same to have been obtained by such processes.[491] Violators of this law can be fined up to $10,000, be imprisoned for ten years, or suffer the imposition of both penalties.[492] The Communist Organization Registration Act of July 1954 requires organizations found by the Subversive Activities Control Board to be Communist-action or Communist-front organizations to provide the Attorney General a listing of all printing presses and machines.[493] The list of different kinds of presses is very extensive.[494] _Censorship of Communications Media_: The War Powers Act of December 1941 specifically empowered the President to establish censorship of communications between the United States and foreign countries. During the existence of the war, the President, at his discretion, established rules and regulations for the censorship of communications by mail, cable, radio, or other means of transmission passing between the United States and any foreign country. The authority to prescribe the rule by which censorship would be applied, extended to communications carried by any vessel or other means of transportation touching at any port, place, or territory of the United States and bound to or from any foreign country.[495]
