摘要：

In this paper, we present an image synthesis method for graphical passwords. Graphical passwords are an authentication method that uses pictures as passwords instead of using alphanumeric characters. However, they are usually easy to memorize for not only users but also observers or attackers who stand behind the users. In our method, we combine low frequency components of a decoy picture with high frequency components of a pass-picture. This makes it difficult for observers to recognize the pass-image.
