1. Secure Reversible Image Steganography Over Encrypted Domain Using Public Key

AUTHOR NAME : Sonali Shevatkar, Dr. C. N. Deshmukh

ABSTRACT : Hiding information in an image in a way that does not affect the original cover image pixels or cause a permanent distortion after extracting that information is known as reversible data hiding technology. Many reversible data hiding schemes have been proposed and successfully applied in military applications. Such schemes are developed to ensure digital images’ authenticity and integrity without any distortion of the original images. They guarantee that any attempt to change the watermarked image will be detected by the image owner. In this research, an algorithm is proposed to reversibly hide data into encrypted grayscale images in a separable manner. The proposed work exploits only LSB insertion for steganography. Scope exists for adopting frequency domain manipulation which may further improve the security of the signal. Comparison with the state-of-the-art methods; the proposed approach provides higher embedding capacity and can perfectly reconstruct the original image as well as the embedded message. Extensive experimental results are provided to validate the superior performance of our scheme.

2. Comparative Study of Development in Techniques for Smart Detection of Fire

AUTHOR NAME : Dr. S.V. Pattlawar, Dr. S.W. Mohod, Neha Randhe

ABSTRACT : The progress on fire detection technologies has been substantial over the last decade due to advances in sensor, microelectronics, and information technologies, as well as a greater understanding of fire physics. This paper provides a review of progress in fire detection technologies over the last decade, including various emerging sensor technologies (e.g., computer vision system, distributed fiber optic temperature sensor, and intelligent multiple sensors), signal processing, and monitoring technology (e.g., real-time control via the Internet) and integrated fire detection systems. Some problems and future research efforts related to current fire detection technologies are discussed.
