Claim:
A data transmission method comprising: capturing a first data transmitted from a first information processing apparatus to a second information processing apparatus; determining whether the first data is streaming data; selectively editing a body data portion of the first data in accordance with a compression format represented by a header of the first data when said determining indicates that the first data is streaming data, the header being extracted from the body data portion for the editing; irreversibly compressing the edited body data portion using an irreversible compression format to ensure that virus program data included in the body data portion is unexecutable; and adding the header to a second data in which the irreversible compression format is described and transmitting the irreversibly compressed body data portion to the second information processing apparatus, and wherein the selectively editing includes one of adding predetermined data to the body data portion and deleting a part of the body data portion based on a ratio determined according to a level of security, by the editing, and the second data is adjusted by a digital processing of at least one of compensation and substitution implemented on the body data portion.
