Hiding Of Host Image Using Cover Image

Bhuvish May 30, 2013

Now digital Medias are becoming very popular among peoples all over the world through World Wide Web sites. The intellectual property of data needs prevention of non-legal copy by unauthorized persons, verification of content integrity and protection of owner’s copyright. The requirements of robustness, security of the hidden data, imperceptibility, data hiding rate, capacity should be satisfied by the newly proposed Data hiding technique. The best and secured way to send and share the host image in a confidential manner is to hiding a host image in a cover image. By this technique we can send important host image efficiently and prevent its unauthorized access by the hackers.

For sending or sharing the image over WWW or via any secured communication over the electronic media the proposed technique i.e. hiding host image using cover image is very efficient and useful technique because we can share host image easily without bothering about loss or gained access by unauthorized users. The authorized user can decode host image only by using designed decoder, so host image is much secured. The host image can be embedded with cover image by using this technique.

The 8 Bit PICCO Processor and it has separate instruction and data memories. Instruction memory: The size of the instruction memory is 4K. Data memory: The size of the data memory is 256 bytes.

SMS Controlled Industrial Controller

Bhuvish May 5, 2013

A project which is developed to control the process in the industry and to check the status of the each process the proposed project i.e. SMS Controlled Industrial Controller is developed. Here we implemented this project using the LAB VIEW. Using this project we can monitor any number of process parameters in the industry. In the existing system it is very difficult for the user to monitor all the process in the industry because he has to be present all the time and maintain system manually. If user is not present, entire system will get damaged. To solve all these drawbacks and disadvantages of existing system proposed, new system is developed. The hardware requirements of the process are fulfilled by the hardware unit of this system.

Cold Boot Attack

Bhuvish May 5, 2013

Most of peoples believe that, in situations like during power failure in modern computers, at room temperature and even when DRAM is removed from its motherboard, DRAMs will retain their contents for few seconds. But DRAMs are not so reliable because hackers can retrieve usable full-system memory images and important contents of DRAMs when DRAMs are not immediately erased/when they are not refreshed. Surprisingly, researches made by the Researchers of Princeton University have clearly shown that the contents of RAM in modern computers remain undamaged after the system BIOS or boot code has finished running, and these can be exploited. To explain this, at the beginning we need to switch off the system and then we will try to capture and analyze the memory of DRAMs.

3D wavelet transform based on lifting

3D Lifting based Discrete Wavelet Transform

We developing a new system that is 3D wavelet transform based on lifting to improve lifting VLSI architecture which uses bi-orthogonal 9 by 7 filter processing. This is the main feature to increase speed and activate higher hardware based utilization, this architecture used efficient pipe lining and parallel design way. Based on time the forms of scale representation, Discrete Wavelet Transform (DWT) architecture provides multi-resolution efficiently.
