Data compression by use of prime exponents

机译:使用质数指数进行数据压缩

摘要

A method of compressing data utilizes the prime number series to generate unique compression parameters that may be used to recover an original data stream. The original data is converted from a binary form to a decimal form. Various compression parameters are selected to initialize the system. The compression parameters include the number of prime numbers which will be used in the compression process and an exponential value corresponding to each prime number. A header is constructed which includes the compression parameters. The data is compressed by a compression algorithm which performs successive division operations by the series of prime numbers selected. The compression algorithm generates a plurality of exponential values corresponding to each of the prime numbers. The header is then assembled with the exponential values and transmitted to a receiving station. In decompressing the data, the prime numbers are raised to the exponential value generated by the compression algorithm, and their product is taken. A fault parameter may be generated to compensate for numbers not readily divisible by the prime number selected in the initialization parameters.
