Communication between a sender and receiver needs security. It can be done in any form,
like plain text or binary data. Changing the information to some unidentifiable form, can save …

Data compression is known for reducing storage and communication costs. It involves
transforming data of a given format, called source message to data of a smaller sized format …

Compression algorithms reduce the redundancy in data representation to decrease the
storage required for that data. Data compression offers an attractive approach to reducing …

Compression is reducing size of data for storage and transmission bandwidth. Image
compression technique is lossless and lossy, the technique is to keep or reduce output of …

Internet and network application are growing at very fast rate, so the need to protect such
application are increased. This paper solves this problem by proposing two different …

We present an algorithm for text compression. The basic idea of our algorithm is to define a
unique encryption or signature of each word in the dictionary by replacing certain characters …

Data security and compression is the common requirement for most of the storage and
transmission related applications. In this paper, a new method for multilevel security and …

Information is all over the place. Laptops, computers, mobiles, everything is flooded with it.
As the days pass by, data is tremendously increasing. Hence transferring, saving and …

We live in a digital era in which communication is largely based on the exchange of digital
information on data networks. Communication is often pictured as a sender that transmits a …

This paper considers different aspects related to two different but not opposite direction-Data
Compression and Cryptography. In this paper a brief review of both of these branches …
