Most block-based image authentication techniques that are presented in the literature
sacrifice localization accuracy in order to resist vector quantization (VQ) counterfeiting …

In some applications, such as surveillance cameras, it is essential that images acquired with
the same device be deemed distinct. To fulfil this requirement, many fragile watermarking …

As the use digital techniques for transmitting and storing images are increasing; it is
becoming an important issue how to protect the confidentiality, integrity and authenticity of …

This paper presents a novel method for the secure management of digital images formulated
within the mathematical theory of polynomial interpolation. As main innovative features, our …

Reversible data hiding is a technique by using which we can embed essential data into
images, audio, video and so on. This system applies a method of hiding data in an image …

To hide hidden data in digital images, a variety of techniques are available, some of which
are more complex than others. Public key cryptography is very useful for applications, and …
