Lossless compression of tabular numeric data

The granted patent US12034463B2 outlines a system and method for lossless compression of tabular numeric data. Central to this innovation is a processor that generates a table of integers from uncompressed numeric information. The process involves rewriting each row of integers as the difference between the current and preceding rows, converting the absolute values of these integers into strings, and concatenating these strings into a single concatenated string. The final step involves creating a compressed data file by writing a byte for each pair of characters in the concatenated string. The claims also specify that the processor can store the sign of each number and calculate the absolute values, enhancing the compression process.

Further details include the use of a base-14 string for concatenation, with separators based on the sign of each number. The processor reserves a new byte array that is half the length of the concatenated base-14 string, ensuring efficient storage. Each byte in this new array corresponds to a pair of characters from the concatenated string. The patent also encompasses a non-transitory computer-readable medium containing instructions for executing these steps, thereby facilitating the implementation of the described compression method in various computing environments.
