Abstract
A method of controlling decompression, wherein the method includes: transmitting, by a first computer that already has stored therein compressed data that are compressed based on compression parameters, identification information for identifying the first computer to a second computer that stores therein the compression parameters; and encrypting, by the second computer, the compression parameters using the identification information received from the first computer. The compression parameters include at least a frequency of appearance and an allocated sign for each piece of character data. The method also includes: transmitting, by the second computer, the encrypted compression parameters to the first computer; decrypting, by the first computer, the encrypted compression parameters received from the second computer using the identification information; and decompressing, by the first computer, the compressed data based on the decrypted compression parameters.
