Steganography is an ancient art of conveying messages in a secret way that only the receiver knows the existence of message. So, a fundamental requirement for a steganographic method is imperceptibility; this means that the embedded messages should not be discernible to the human eye. There are two other requirements, one is to maximize the embedding capacity, and the other is security. The lea...

Steganography is the science of hiding messages in a manner that only the intended users knows the presence of the secret message. Hiding the information within a computer file also comes under Steganography. In digital steganography these media files are suitable because of their large size. LSB insertion is one of the basic techniques prominently used in steganography. This paper presents an ...

to be published in the Journal of Vision Researchers on human perception have devised a number of methods for measuring perceived location and using it to assess perceptually guided action. Such work has primarily been performed in space accessible by reaching and walking. Here we use the same approach to assess perceptually guided action in very near space, specifically, in the applied context...

Many large polyatomic molecules attach free low-energy electrons to form parent negative ions that subsequently decay by autodetachment, reverting to a neutral molecule and a free electron. Their lifetimes against autodetachment, however, span a broad range. This is consistent with a simple model in which it is assumed that electron capture initially forms an excited intermediate in which only ...

In this information era, digital information sharing and transfer plays a vital role and their use has increased exponentially with the development of technology. Thus providing security of data is a topic of concern. Data hiding is a powerful tool that provides mechanism for securing data over insecure channel by concealing information within information. Steganography inherits data hiding con...

Steganography is an art of hiding secret messages such that its very presence can’t be identified. Techniques which hide more secret data in cover files are better and they will be more better if they doesn’t affect transparency of cover signal and make steganalysis difficult. We propose a technique which provide keyless randomization to insert secret information in multiple and variable LSBs. ...
