Abstract:

In order to solve the problem that the hidden image through transform processing will lose secret information before uploaded to social network, this paper proposes a novel scheme that hides secret information securely into images. In the scheme, firstly, JPEG images are decoded incompletely. Then, JSteg algorithm is improved based on discrete cosine transform and JSteg steganography technique, which secret information is embedded into decoding information. Finally, the recoded JPEG images are uploaded to social network. This paper designs and implements a prototype system that hides information into images by using the scheme. After the processing of the system, the image uploaded to social network can be downloaded, and the encoded secret information can be decoded through a specified decryption technique, so as to achieve the purpose of hiding secret information to the image.

Key words: social network, discrete cosine transform, image coding, information hiding
