Applying personal character image for commercial purpose has a long lasting history in daily commerce. As the mirror image of right of personality under U.S. legal system, right of privacy has been called on in cases of such commercial exploitation. U.S. court, however, persistently denied such claim and therefore induced the development of right of publicity. With lack of such right, Taiwanese court applied right of personality as the legal remedy. Comparing the similarity in function between right of personality and right of privacy, the reason why two rights with similar purposes could reach different conclusions is of great interest. By comparing the verdicts delivered by Taiwanese and U.S. courts, this article sorts out the reasons why U.S. courts denied right of privacy and explain how the right of personality under Taiwan legal system can bypass such difficulties.
