A phone-mediating trading system and a method for use with the same are provided. After the user uses a user phone to construct linkage to the trading host, the trading host generates a set of random data to the user phone where the set of random data is encrypted with a private key designated to the user phone. The encrypted set of random data is transmitted to the trading host, and decrypted through the use of a public key that is stored in the trading host and corresponds to the user's phone number. If the decrypted set of random data, as determined by the trading host, is the same as the originally-generated set of random data, the user is allowed to perform trading with the trading host. This method is efficient and convenient to implement without performing a conventional complex identification process for identifying the user.
