Abstract

The invention relates to an image steganography and secret information extraction method based on an intelligent mobile terminal. The intelligent mobile terminal comprises a secret information embedder, a secret information extractor and a multimedia message transmitter, and images are selected by the intelligent mobile terminal for different use purposes. If secret information needs to be embedded, original pictures are selected. If the secret information needs to be extracted, encrypted pictures are selected. The selected original pictures are uploaded into the secret information embedder for the secret information embedding operation, and the encrypted pictures are uploaded into the secret information extractor for the secret information extraction operation. If the current operation is the secret information embedding operation, the encrypted pictures embedded with the secret information are uploaded into the multimedia message transmitter, and are sent to a receiver in a multimedia message mode. Compared with the prior art, the image steganography and secret information extraction method has the advantages that the functions of secret information embedding, multimedia message sending and secret information extraction are achieved in the intelligent mobile terminal, system safety is enhanced, and meanwhile multimedia message sending efficiency is improved.

Description

technical field [0001] The invention relates to an image steganography method and a secret information extraction method based on a mobile intelligent terminal. Background technique [0002] With the advent of the mobile Internet era, smart mobile terminals represented by Android, iOS and Windows Phone 8 have been widely used. Through the use of mobile smart terminals, people transfer information to each other every day, which has become an inseparable tool for people's study, work and life. The MMS service in the mobile information service has enriched the ways of communication between people, and also facilitated many mobile phone users. With the development of 3G network, data communication has become the general trend, and MMS, as a representative of data communication, has become the first choice of the majority of users. Utilizing the MMS service, users can transmit richer multimedia information, such as pictures, audio and video information, to each other. MMS, as ...
