Title: Image Authentication and Tamper Localization
Abstract: Image authentication can be used in many fields, including e-government, e-commerce, national security, news pictures, court evidence, medical image, engineering design, and so on. Since some content-preserving manipulations, such as JPEG compression, contrast enhancement, and brightness adjustment, are often acceptable—or even desired—in practical application, an authentication method needs to be able to distinguish them from malicious tampering, such as removal, addition, and modification of objects. Therefore, the traditional hash-based authentication is not suitable for the application. As for the semi-fragile watermarking technique, it meets the requirements of the above application at the expense of severely damaging image fidelity. In this talk, we propose a hybrid authentication technique based on what we call fragile hash value. The technique can blindly detect and localize malicious tampering, while maintaining reasonable tolerance to conventional content-preserving manipulations. The hash value is derived from the relative difference between each pair of the selected DCT coefficient in a central block and its counterpart which is estimated by the DC values of the center block and its adjacent blocks. In order to maintain the relative difference relationship when the image undergoes legitimate processing, we make a pre-compensation for the coefficients. Finally, we point out the direction using deep leaning technique for image authentication.
Prof. Franklin Bien
Ulsan National Institute of Science and Technology, South Korea
Prof. Franklin Bien received the B.S. degree from Yonsei University in 1997. He received his M.S. and Ph.D. degrees from the Georgia Institute of Technology at Atlanta, GA in 2000 and 2006 respectively. Dr. Bien’s heritage roots from Dr. Joy Laskar. This also means Dr. Bien’s heritage roots from a Nobel laureate and the father of ‘transistor’, Dr. John Bardeen as you can see from the ‘People’ tab. Prior to joining UNIST in 2009, Dr. Franklin Bien was with Staccato Communications, San Diego, CA as a Senior IC Design Engineer working on analog/mixed-signal IC and RF front-end blocks for Ultra-Wideband (UWB) products such as Wireless-USB. Before working at Staccato, Dr. Bien was with Agilent Technologies and Quellan Inc., developing transceiver ICs for enterprise segments that improve the speed and reach of communication channels in consumer, broadcast, enterprise and computing markets. In the early stage of his career including the Ph.D. work, Dr. Bien’s research interests included signal integrity improvement with alternate modulation schemes, cross-talk noise cancellation, and equalization techniques for 10+Gb/sec broadband communication applications. Dr. Bien’s research and design experiences includes CMOS RF front-end circuits for UWB wireless communications, adaptive circuits for wireless power transfer (WPT) applications, and electronics design for future automobiles and electric vehicles.
Title: Control Loop enabled Full RF Glucose Sensing Technology
Abstract: Diabetes affect more than 425 Million patients worldwide responsible for over 5 Million annual death. Diabetes patients must monitor their glucose levels in order to have proper medical treatment including insulin injection and others. Unlike the commonly known Type 2 diabetes, there is a Type 1 diabetes whose pancreas doesn’t function properly. This affects more than 50 Million patients world wide, and they must monitor their glucose levels more often, at least every hour. As a result, conventional pricking method to monitor the glucose levels can be cumbersome and painful for the Type 1 diabetic patients. In order to enhance the quality of life for Type 1 diabetic patients, an alternative way to the pricking method has emerged: the Continuous Glucose Monitoring (CGM) systems. The CGM in the market today uses an enzyme based sensors that need to be replace every week resulting in very high cost for the patients while causing skin rash problems. In this talk, we present a Control loop enabled fully electromagnetically sensing CGM technology that excludes any enzyme based electro-chemical based sensors.
