STRENGTHENING DYNAMIC CELL SPREADING (DCS) IMAGE STEGANOGRAPHY

摘要：

　　Dynamic Cell Spreading (DCS) steganography has advantages in terms of security because it uses a bit stream as a key and in terms of speed as it involves the allocation of memory.But there are still weaknesses which is the current distance of bits to cover information is still limited such that it will decrease the security strength.To overcome this problem,this research carried out modifications to the bit stream generation for overcoming the weakness and improve the security while still maintaining system performance.The modification is made by modifying bit stream using PRNG and hash function.Then the results of these modifications will be implemented on a system that is built and further will be analyzed as well.Using this method the security of modified Dynamic Cell Spreading was improved while maintaining system performance.
