Analysis of Invisible Image Watermarking Based on Spatial and Frequency Domain Techniques (LSB, Patchwork, DCT, DWT, DFT)
Abstract: AbstractWith rapid development, seed technology, secure transmission of information is very intricate. For harmless and protected transmission of information, digital watermarking can be utilized. Watermarking of advanced images is a system of concealing information; likewise, it gives security of information or distinguishing data in the computerized information. The computerized watermarking process implants a sign into the media without altogether debasing its visual quality. We additionally talk about a portion of …

Adapting LSB Method on Bit-Plane for High-embedding Ratio of Steganography
Abstract: Internet is one of the medium of communication mostly used now a day. To conserve the security of information sent over the internet, steganographic concept makes its arrival. Least-significant bit and multi-bit embedding methods are the most well-known and familiar in this domain. Here, in this work, only least-significant bit method is used. It is a new technique which is indeed very simple in comparison to the other existing ones …

An Evolution of the Pixel Embedding Techniques in Image Based Adaptive Steganography
Abstract: The word “Steganography” was basically derived from the Greek words with the meaning “covered writing.” This paper presents some of the main adaptive image steganography approaches. Many algorithms have been presented; in almost all the algorithms the approach is to embed the secret data in the images. Here we are discussing about adaptive steganography which is based upon spatial domain and frequency domain with an additional layer of mathematical model. …

Design of a 10-bit Segmented Current-Steering CMOS D/A Converter for High Speed Communication System
Abstract: In the present work, design of a 10-bit digital-to-analog (D/A) converter using current segmentation architecture in 0.35 µm double-poly, four-metal, CMOS process has been attempted. The measured differential nonlinearity (DNL) and integral nonlinearity (INL) are 0.8 and 2.5 least significant bits (LSBs) respectively. For sampling frequency of 12-MSample/s, the spurious free dynamic range (SFDR) is better than 56 dB for signal up to Nyquist rate. The worst case power consumption …

Reduced Partial Product Booth Multiplier with An Effective Error Compensation Circuit
Abstract: Reduced partial product Booth multiplier is mainly used in multimedia and digital signal processing (DSP) systems. In this paper, design of reduced partial product (constant-width) Booth multiplier is introduced. Here the least significant bit (LSB) of partial product matrix of Booth multiplier is removed and an error compensation function is derived for reducing truncation error. A simple error compensation circuit (SC generator) is also introduced to reduce the computations that …

Design a Framework for Cybersecurity Using Steganography
Abstract: AbstractNowadays with the rapid increase in transmitting data’s through computers, securing these transmitted data is mandatory. The most common and desired technique used to secure these data is Cryptography. Cryptography consists of two steps, namely Encryption and Decryption. But they are not much safe compared to steganography. This study aims to design a framework for cyber security using steganography to increase the security level of data to be transmitted, using …

Watermarking Analysis of Digital Image Using Various Approaches: A Review
Abstract: AbstractFor present security to the digital media on the net the very beneficial generation is, virtual watermarking (DW). Watermark is an image or pattern in document which is used to identify data authentication and data integrity. The user can check the watermarked records with the watermark key and watermarking extraction system. The different techniques of watermarking reviewed in this paper are: least significant bit (LSB), robust, discrete cosine transform (DCT), …

Speech Hiding in a Digital Image using DWT and DES Algorithm
Abstract: AbstractThe proposed paper presents a speech hiding technique in a digital image (DI). Here the technique used is Discrete Wavelet Transform (DWT). It secures speech signal from unauthorized users. It can be done by embedding speech into an image by steganography. Thus, unauthorized users will not detect secret speech in stego image. Suppose unauthorized users detect the speech that will be fraud because no one can obtain speech signal without …
