Abstract: A data converter for converting a file having layout information to a file which does not depend on the process properties of an information apparatus is provided. The process which is executed by the control part in the data converter includes the step of determining the attributes of the apparatus to which mail is transmitted if a file is attached to received mail, the step of executing a conversion process if data conversion is necessary, the step of generating a message that mail is incoming which includes information on the location where the file that has been generated through the conversion process is stored, the step of transmitting the message that mail is incoming to the recipient's apparatus, the step of storing the file without converting data if data conversion is unnecessary, and the step of transmitting the received mail to the recipient's apparatus.

Abstract: A document data display system uses document data composed of text and image portions and layout information and creates from it compressed document data by lossless compressing the text portion and lossless or lossy compressing the image portion in order to reduce traffic in communication. A document data display device 1 expands text or image portions from received compressed document data at a text expansion unit or an image expansion unit, and uses the analysis of the layout information by a layout information analyzing unit to arrange the text or image portions at a development unit before being displayed by a display unit.

Abstract: A data use limitation setting method is arranged so as to include a data receiving step of receiving from a user terminal device, (A) content data and (B) user authentication data corresponding to the content data; an authentication judging step of judging in accordance with the user authentication data, success or failure of authentication; and a data use limitation setting step of, if the success of the authentication is judged in the judgment, setting on the content data, a data use limitation for limiting use of the content data. With this, it is possible to widely provide as a system for limiting the use of content data, a highly reliable system that is not easily subjected to unauthorized analysis.
