The aim of this work is to develop an application which can be used for privacy and security purposes over an open environment like internet. The application also provides multilayer security in the form of steganography, which is used to hide the data into the image and secondly, cryptography in order to encrypt the image with a key. Application developed is based on Image Steganography by converting the data into streams of bits and then hiding the data inside an image. Digital images are considered better because of their high usage not only in the daily life activities but also on...

The objective of this work is to make a virus free environment for organizations. The solution of the problem is devised in the form of a dedicated system with integrated modules at hardware level. The proposed system is going to protect computer systems against malware activity. Hardware oriented approach with dedicated module along with integrated components can help in controlling the malware activity during system boot-up and provides security after the start-up of operating system. Moreover, hardware based management port is also introduced to keep traces of web activity for deployment...
