Today’s large demand of internet applications requires data to be transmitted in a better manner. Data is transferred in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the better solution for this issue is Steganography, which is the technique of writing hidden messages in such a way that no one, apart from the sender and main rec...
The Digital watermarking is a field of information hiding that entails the crucial in original data order to prevent illegal duplication and distribution multimedia such as image, video, text ect.. In this paper, we present two techniques embed watermarks cover image. first Least Significant Bit (LSB) method, which spatial domain technique considered fragile against attacks other operations. se...
Digital Rights Management (DRM) system is the effective scheme for digital transactions. The main disadvantage of DRM is that once the content is decrypted, it can be easily copied using widely available utilities. It can be removed by using protection system like steganography. Steganography is the art of communicating in a way which hides a secret message into the main information or cover. T...
There is an increasing focus on promoting person-centred systems across continuing care settings, emphasizing the need to enhance the quality of life of older adults. Life story books (LSB) can provide a holistic view of older adults, promote relationship-centred care and enhance person-centred care. The process of developing LSB involve collecting and recording aspects of a person's life both ...
We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped-Lyα (DLyα) absorption line in the spectrum of the background QSO HS 1543+5921 (ze = 0.807). We obtain an accurate measure of the velocity of the H I gas in the LSB galaxy, v = 2868 km s, and derive a mass of MH I = 1.3× 10 9 M⊙. We compare MH I with limits obtained towards two other ...
This paper presents a novel method for detection of LSB matching steganography in grayscale images. This method is based on the analysis of the differences between neighboring pixels before and after random data embedding. In natural images, there is a strong correlation between adjacent pixels. This correlation is disturbed by LSB matching generating new types of correlations. The presented me...
Secret sharing is the process of distributing a secret amongst a group of participants each of whom is allocated a share of the secret. This secret can be reconstructed only when a enough number of possibly different types of shares are combined together. Individual shares have no use here Steganography can applied on video files and hide the message in an encrypted format thus achieving a mult...
Digital watermarking is a method which is used to verify texts, image, video etc. Watermarking Technique is not only used for Authentication, it’s also used for security, image protection, rights of documents. In this perspective experiment we used edge detection technique in watermarking for the purpose of highly authentication of image. Here we used combined approach of LSB-DCT watermarking f...
This paper presents a novel 2-3-3 LSB insertion method. The image steganography takes the advantage of human eye limitation. It uses color image as cover media for embedding secret message.The important quality of a steganographic system is to be less distortive while increasing the size of the secret message. In this paper a method is proposed to embed a color secret image into a color cover i...
Through dynamic compensation of pixel values of the LSB (Least Significant Bit) embedded image, this paper presents a novel LSB information hiding method against pixels Sample Pairs Steganalysis (SPA), a powerful steganalysis method proposed by Dumitrescu et al. with high precision. This approach embeds messages in the LSB plane of the carrier image randomly via a chaotic system, then makes a d...
