Can you obtain and read the AT command manual for the GSM Modem you have chosen for your project? Have you done that? Do you think the purpose of the project is to test your own abilities, not those of the internet denizens.
Depending on the modem there is usually a number of ways to read the phone number for the SIM card present. You could also hard code other white listed numbers. When you enumerate through and process the SMS messages with AT+CMGR, check the sending party and send back with AT+CMGS to either that or the "owner".
