In recent times, the application of deoxyribonucleic acid (DNA) has diversified with the emergence of fields such as DNA computing and DNA data embedding. DNA data embedding, also known as DNA watermarking or DNA steganography, aims to develop robust algorithms for encoding non-genetic information in DNA.

Bài báo này trình bày một hệ thống truyền tin mật an toàn, kết hợp các thuật toán mã hóa mạnh mẽ nhất (AES, RSA và SHA3) với kỹ thuật giấu tin trong video 3D. Sự kết hợp này tạo nên một hệ thống truyền tin mật mạnh mẽ trước nhiều loại tấn công thám mã và giả mạo. Dữ liệu mật sẽ được mã hóa bởi các thuật toán đủ mạnh trước khi nhúng vào video 3D bằng kỹ thuật Steganography.

In this contribution, criteria for the sequences employed in spread spectrum (SS) watermarking and steganography are discussed. These criteria are: Sharp autocorrelation function (ACF), large linear complexity (LC), large length (L), normal distribution assumption and bi-polar.

Providers of cloud give opportunity to customers to avoid start-up costs and reduce operating cost and access data properly. So to increase security in cloud computing steganography technique is used using genetic algorithm. This will protect stored data in cloud from unauthorized access.

This paper presents the issues and challenges faced for image steganographic techniques. Many LSB method techniques were developed in recent year using direct or un-direct position to embed secret message into cover. Some techniques for embedding information in Image files were reviewed, and recommendations are being proposed for the best strategy of hide information in image files and the possibility of finding other new techniques hiding information in image files.

This paper simulates an effective data hiding technique i.e. steganography based on LSB insertion and RSA encryption in order to provide seven million times better security than the previous work. The Main idea of proposed scheme is to encrypt secret data by RSA 1024 algorithm, convert it in to binary sequence bit and then embedded into each cover pixels by modifying the least significant bits (LSBs) of cover pixels. The result image is also known as steganography image.

The term "biometrics" is derived from the Greek words bio means “life” and metric means “to measure”. In this paper, a detailed experimental study of physiology biometrics (face, iris) detection, face detection algorithms based on “Skin Color” has been made.

Instead of embedding secret data anywhere in image, it will be embedded in only skin tone region. This skin region provides excellent secure location for data hiding. So, firstly skin detection is performed in cover images and then Secret data embedding will be performed in DWT domain as DWT gives better performance than DCT while compression. This biometric method of Steganography enhances robustness than existing methods.
