    摘要: A communication system limits use of compressed dictionary content stored in a mobile communication terminal to only the mobile communication terminal. The mobile communication terminal transmits terminal identification information to a communication server. The communication server uses the received terminal identification information as a master key to encrypt compression parameters and transmits encrypted compression parameters to the mobile communication terminal. The mobile communication terminal decrypts the compression parameters encrypted using the terminal identification information and uses the decrypted compression parameters to decompress the compressed dictionary content.

    摘要: 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.
