Filed: 2019-10-10
Abstract: The invention relates to a compressing method of binary data. First, data to be compressed is compressed with a known compression algorithm as shown in a figure below (in this embodiment, a Deflate algorithm is applied). Then, with n-bit binary data to be further compressed (referred to as an original key), the compressed data is modulated. A modulation rule modulates the k^th byte of the compressed data by inverting the same when the k^th bit of a binary bit string is 1, and by leaving the same as it is when the value is 0. Modulation rules can be very diverse and all modulation rules that are uniquely differentiated by a binary bit string and 1:1 are included. The data modulated in this way is used as final compressed data.
