摘要：A lossless compression algorithm, for genetic sequences, based on exact Four Bases Block(FB2) conversion, each bases are define by a single decimal/binary value, convert each block of base into equivalent number of decimal value, the range of decimal value is vary from 0 to 255 and each decimal equivalent value are encoded by corresponding ASCII code. Each base define as a=0, t=1, g=2 & c=3 in case of decimal coded and a=00, t=01, g=10 & c=11 in case of binary coded, this values are user specified for better security. It can provide the data security, the exact coded value are necessary for decoding time by using only exact coded value provided by encoded time, this proposed method protect the data by using ASCII code, this types of data security in tier one. In tier two, use selective encryption techniques for better securities. Speed of compression and security levels are two important measurements for evaluating any encryptioncompression system. This method are use only particular available ASCII code for compression purpose and pattern are use for selective encryption purpose. The running time of this algorithm is very few second, varies linearly with the size of the source file to be compressed and the complexity is O(n). The algorithm can approach a compression rate of 2.00002 bits/base.
