BURROWS WHEELER BASED DATA COMPRESSION AND SECURE TRANSMISSION

Burrows Wheeler Based Data Compression and Secure Transmission

Now days, computer technology mostly focusing on storage space and speed With the rapid growing of important data and increased number of applications, devising new approach for efficient compression and encryption methods are playing a vital role in performance. In this work, burrows wheeler transformation is introduced for pre processing of the input data and made several performance analysis...

Burrows Wheeler Compression

Author’s Note. The material of this chapter, while quoting extensively from other work, is in part a summary of my own experience and thoughts in working with the Burrows-Wheeler compression algorithm. Some of it is accordingly rather less formal in style than might otherwise be the case, as I give more personal opinions on various aspects. Where my own work already appears in the public domain...

Modiications of the Burrows and Wheeler Data Compression Algorithm

Modifications of the Burrows and Wheeler Data Compression Algorithm

In 1994 Burrows and Wheeler [3] described a universal data compression algorithm (BWalgorithm, for short) which achieved compression rates that were close to the best known compression rates. Due to it’s simplicity, the algorithm can be implemented with relatively low complexity. Fenwick [5] described ideas to improve the efficiency (i.e. the compression rate) and complexity of the BW-algorithm...

Burrows-Wheeler compression: Principles and reflections

After a general description of the Burrows Wheeler Transform and a brief survey of recent work on processing its output, the paper examines the coding of the zero-runs from the MTF recoding stage, an aspect with little prior treatment. It is concluded that the original scheme proposed by Wheeler is extremely efficient and unlikely to be much improved. The paper then proposes some new interpreta...
