Methods for processing information to be substantially unintelligible by a machine but understandable by a person include disguising information in the form of text and creating a graphical image file of the text. The text may be disguised before, during or after the creation of the graphical image file. The text may be disguised by manipulating the characters of the text, such as by replacing characters of the text by other characters having a similar appearance or by words corresponding to the characters, or by adding obviously superfluous characters or words to the text, for example. The text may also be disguised by processing the graphical image file to provide a background to the text which has low contrast with respect to the text. An alpha-numeric or textured background may be provided, for example. The graphical image file may be part of a Java Applet. Text may also be disguised through direct encoding in a Java Applet. It would be difficult or impossible for a machine to accurately capture the disguised information with a harvesting program, even if the program used optical character recognition. Information may also be disguised in the form of a dynamic media, such as audio or video. Creation of the audio or video file may be sufficient disguise; the information may be further disguised, as well. The audio or video file may also be part of a Java Applet. Once again, it would be difficult or impossible for a machine to accurately capture such information. The invention is particularly suited for disguising personal information on a communications network, such as an e-mail address on a web page stored on the World Wide Web. Computer readable media storing the media file, software executable to disguise the information, web sites including the disguised information and servers storing the disguised information, are also disclosed.
