Abstract
The invention relates to a method for realizing a switchable multi-cipher local information encryption box. The traditional encryption method mainly comprises two types: (1) single cipher protection which does not support the form that a plurality of encryption boxes are divided according to information sources or contents; and (2) a plurality of cipher protections by which the number of the encryption boxes can be listed or presumed. In the method, a user can select classify information to a certain encryption box according to information sources and information contents; the encryption boxes can be switched at any time when a certain encryption box is needed to be checked; a cipher is needed to be provided when the encryption boxes are switched; the information is correctly deciphered when the cipher is correct, and blank is displayed when the cipher is wrong; and other people cannot judge whether the cipher is wrong or no corresponding encryption box is provided and cannot also know how many encryption boxes owned by the user, therefore, the aims of information hiding and privacy protection are achieved. The method is suitable for encryption of short messages, instant messages, e-mails, pictures, files and other information and has the advantages of flexibility and good privacy.
