Abstract
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.

8. A phone-mediating trading method, for allowing a user with a user phone to be linked to at least a trading host via a public telephone system;
- the phone-mediating trading method comprising the steps of;
(1) constructing linkage via the user phone to the trading host through the public telephone system, and asking the user to input identity-identification data to the trading host; (2) generating a set of random data via the trading host to the user phone; (3) encrypting the set of random data via the user phone through the use of a private key that is designated to and stored in the user phone, and than transmitting the encrypted set of random data to the trading host; (4) decrypting the encrypted set of random data via the trading host through the use of a public key that is stored in the trading host and corresponds to the user'"'"'s phone number; (5) determining via the trading host if the decrypted set of random data is the same as the original set of random data generated from the trading host;
if no, proceeding to step (6);
if yes, proceeding to step (7);(6) prohibiting the user from performing phone-mediating trading with the trading host as the decrypted set of random data is different from the originally-generated set of random data, which indicates the private key stored in the user phone is incorrect; and (7) permitting the user to perform phone-mediating trading with the trading host as the decrypted set of random data is the same as the originally-generated set of random data, which indicates the private key stored in the user phone is correct. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
