Blind decryption is an efficient way of protecting customer’s privacy in online marketing over the Internet (i.e. Hiding information about which goods a user purchases from the vendor). In this study, the RSA based blind decryption is simply transposed from an identical protocol as the Chaum’s blind signature scheme and the blind decryption protocol for the Elgamal encryption scheme is suggested. In addition, the difference between the known RSA based blind decryption protocol and our proposed protocol is examined in applications to protect copyright subjects of e-commerce documents over the internet.
