| Abstract: | This paper proposes a cover image sharing steganographic algorithm based on the Bernstein polynomial for the problem of small steganography capacity and poor security of image sharing. It constructs image sharing steganograpbic model, describes the properties of Bernstein polynomial and proves sharing principle. Algorithms of embedding and extraction are given, experiments of image sharing steganography and anti-attack are completed. Experimental result and analysis show that the algorithm increases embedding capacity, reduces the perceived quality of cover image and improves security of secret information. |
| Keywords: | image sharing information hiding Bernstein polynomial steganography security perceived quality |
