ElGamal-Based Improved Least Significant Bit Information Hiding Algorithm Design

Abstract

In the current network environment, data security and privacy threats are becoming increasingly diverse and complex. So the single use of information hiding technology or image encryption technology for information transmission can no longer meet the requirements of safe and reliable transmission, and a method combining information hiding and image encryption is proposed to protect the data in two layers. The first layer uses the improved least significant bit information hiding algorithm to embed the secret information into the carrier image, and the
