Abstract

Internet of Things (IoT) serves as part of our routine life activities nowadays and the secrecy of data has been compromised and cyber-crimes are increasing at an alarming rate therefore, the needs of a secure environment is vital in order to secure the transmitting data. This calls for a method to secure the digital messages being sent over the internet. In this paper we propose a modified concept on hiding the confidential data in an image. Here the Image Steganography is achieved using Modified LSB. Modified LSB uses a certain condition to replace the bits of the confidential data at the least significant bit position of the pixels in the image so Cryptography approach is achieved using AES. In this way, Steganography and Cryptography when used together ensures enhanced security of digital messages. Experimentally we found that the proposed approach is less prone to passive and active attacks. Also, as in nature it is hybrid approach which preserves the confidentiality of the information better than existing approaches.
