Speech 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.

Speech 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.
