This paper presents an experimental study on the security performance of Yet Another Steganographic Scheme (YASS). It reports: 1) YASS’s security performance with different input images, i.e., uncompressed images and JPEG compressed images; 2) YASS’s security performance compared with two other JPEG steganographic schemes MB1 and F5; and 3) some experimental results about extended YASS.

030-Improving Biometric Authentication Performance From the User Quality
September 28th, 2010 
Projects-Netizen The effectiveness of a biometric measurement and sensing system is directly related to the performance generated from sensed data. This paper investigates a new approach to quantify the quality of sensed data from the user templates. The objective is to incorporate the quality of sensed data to generate a reliable estimate on the matching scores. [...]
031-A Postural Information-Based Biometric Authentication System Employing S-Transform, Radial Basis Function Network, and Extended Kalman Filtering
September 28th, 2010 Projects-Netizen This paper proposes a new system for biometry-based human authentication, where postural signal information is utilized to identify a person. The system employs a novel approach where four types of temporal postural signals are acquired for each person to develop an authentication database, and for each posture, both signals in the $x$- and $y$-directions are [...]
032-Biometric Authentication System on Mobile Personal Devices
September 28th, 2010 Projects-Netizen We propose a secure, robust, and low-cost biometric authentication system on the mobile personal device for the personal network. The system consists of the following five key modules: 1) face detection; 2) face registration; 3) illumination normalization; 4) face verification; and 5) information fusion. For the complicated face authentication task on the devices with limited [...]
