Item A Novel Approach to Video Steganography using a 3D Chaotic Map(Institute of Electrical and Electronics Engineers Inc., 2019) Narayanan, G.; Narayanan, R.; Haneef, N.; Chittaragi, N.B.; Koolagudi, S.G.In this paper, we introduce a novel approach for data-hiding in videos using 3-dimensional Chaotic Maps. A video is represented as a 3-dimensional image, with the third axis constituting the frames of the video. Existing chaotic map based data-hiding techniques on videos is confined to applications of 2-dimensional chaotic maps on a per-frame basis. In this paper, a 3-dimensional extension of the logistic chaos map is applied to identify pixels to encode information in the video's 3-dimensional space and 3-3-2 Least Significant Bit (LSB) substitution is used to encode 1 byte of information per pixel. We have implemented and presented a proof of concept that has been analyzed on a test video using various quality metrics. The chaotic map based data-hiding approach proposed in this paper is shown to be secured and the results observed are inline with the standard results for a video steganographic algorithm using LSB substitution. © 2019 IEEE.Item Dependency of routing protocol on pH and SNR in Underwater Communications(Institute of Electrical and Electronics Engineers Inc., 2021) Haneef, N.; Chandavarkar, B.R.Underwater communication is very critical in today's world with the advent of IoT devices which require proper communication standards and protocols to be in place for improving performance. Routing protocols is one such important feature of underwater communications which helps devices pick the best route based on different parameters. In this paper we designed and implemented an On-Demand Routing protocol which uses pH of the water and the SNR to choose the best hop while forming a route in underwater communications. The effects of pH on SNR were studied and the various factors affecting pH were observed. A pH model was developed using the data collected from the Hawaiian Ocean Waters.The routing protocol was designed and implemented in UnetStack3 as well. © 2021 IEEE.
