“…Different research works have been done on patient data for reducing their size using LZW [9] , LZMA with LZ77 [10] , [11] , Deflate/Huffman coding [12] , [13] , [14] , [15] , [16] , Run-length encoding (RLE) [17] , LZ4 [18] , [19] , LZO [18] , [19] , and BZ2 [11] , [18] . Although these existing techniques are being used for compressing patent data, they do not provide better performance due to having fewer identical samples or multiple occurrences of repetitive substrings in data [15] , [20] .…”
