Abstract
With development of the information technology, Information security issues are attracting increasing attention. Information hiding technology can hide secret information in the non-secret information (such as audio, video, static graphics and text) thus people will have no sense with the change about the information hiding carrier. In recent years, information hiding technology has a high speed development, people proposes many information hiding method and algorithm. Now information hiding technology has already had widespread application in multimedia information copyright protection and information security etc. The design of the hidden tools is a need to use a hidden message encryption algorithm encrypted form dense text to a file or into a code without influence the file or picture. So as to let other people can’t see the confidential document. Thus the information has been hidden.The relevant demand of the graduated design: using the VC++ 6.0 to make a tool, the function of the tool is that set up a password for the inputted information by a kind of arithmetic. Then the information be kept into a picture and the picture still can be seen normally. At last, the information has been hidden.
