Abstract: A transmitter cell phone 10 is provided with a controller 11 for fulfilling functions of a data encryptor, a first key encryptor, and an encryption file generator. The data encryptor encrypts data, using a first encryption key. The first key encryptor encrypts the first encryption key, using a second encryption key. The encryption file generator generates an encryption file of the data from the data encrypted by the data encryptor, the first encryption key encrypted by the first key encryptor, and user-specific information permitting identification of a user of the mobile communication terminal.

Abstract: An information communication system 1 according to the present invention is comprised of a cellular phone 10 having a data storage 11, a data list transmitter 13, and a data transmitter 16; and a cellular phone 20 having a check list DB 21 and a data receiver 26. The cellular phone 10 makes the data list transmitter 13 transmit a data list of content data stored in the data storage 11, to the cellular phone 20. The cellular phone 20 collates the data list with a check list stored in the check list DB 21 to generate a request list, and transmits the request list to the cellular phone 10. The cellular phone 10 extracts the content data recorded in the received request list from the data storage 11 and transmits the content data to the cellular phone 20. The cellular phone 20 receives the content data through the data receiver 26.
