As the use of information technology spreads out in a variety of daily life, there is strong need for personal information protection using smart cards. In this paper, we propose a novel multimodal security enhancement scheme for Java cards. Here we emphasize two aspects. One is using multiple PINs, namely Stored_PIN, Install_PIN, and Update_PIN, which allows providing different security-level services to diverse applets and/or users that have different security requirements. The other is applying cryptographic algorithms to make a PIN setting and verification activity more trustworthy. Real implementation based study has shown that our proposal can improve multiformity, key manageability, and confidentiality with lightweight space and time overheads.

This paper handles the UX implementation for system control using the visual input information of hand motion. Kinect sensor from Microsoft is used to acquire the user's skeleton image from the 3-D depth map at a rate of 30 frames per sec. and eventually knows the x-y coordinates of hand joints. The x-y coordinate value changes of hands between the present frame and next frame shows the direction of changes and rotation of changes and the various hand motion is used as a UX input command for remote image control on smart TV, etc. Through the experiments, we showed the implementation of the proposed idea.
