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 experiments over different compression techniques for various types of text files and improved compression ratio has been found by applying burrows wheeler transform as pre-processing step.
