- Privacy-Preserving Image Compression and Machine Learning for Untrusted Cloud Environments
- Progress and Challenges in Compressible and Learnable Image Encryption

Hitoshi Kiya

 With the wide/rapid spread of distributed systems for information processing, such as cloud computing and social networking, not only transmission but also processing is done on the internet. However, cloud environments have some serious issues for end users, such as unauthorized access, data leaks, and privacy compromise, due to unreliability of providers and some accidents. Accordingly, we first focus on compressible image encryption schemes, which have been proposed for encryption-then-compression (EtC) systems, although the traditional way for secure image transmission is to use a compression-then encryption (CtE) system. EtC systems allow us to close unencrypted images to network providers, because encrypted images can be directly compressed even when the images are multiply recompressed by providers. Next, we address the issue of learnable encryption. Huge training data sets are required for machine learning and deep learning algorithms to obtain high performance. However, it requires large cost to collect enough training data while maintaining people’s privacy.

Precision antenna measurements for 5G and EMC frequency band.

Satoru Kurokawa

 Recent progresses in wireless communication technologies are remarkable for broadband wireless internet and mobile communication systems. First step of 5th generation mobile network uses around 3.7, 4.5 and 28 GHz frequency bands in Japan. Radiated electromagnetic interference (EMI) measurement must be done in the radiated electromagnetic field intensity using broadband antennas up to 18 GHz. To evaluate the antenna characteristics for these frequency bands, we usually use double-ridged guided-horn antennas up to 18 GHz and WR-28 band standard gain horn antennas from 26.5 to 40 GHz as standard antennas. In this talk, we show our proposed free space far field antenna factor measurement method using time domain and pulse compression techniques for EMI broad band antennas. Further, we explain our proposed single antenna calibration method for EMI broad band antennas. Then, we also show our proposed single cut-plane near-field to far-field transform method for base-station antennas. Finally, we explain our developed bi-directional optical-fiber-link transceiver systems that can replace coaxial cables in many measurements.

Applying Acoustic Signal Processing and Artificial Intelligence in Smart City:
How we are translating our research work to smart city testbeds? .

Woon-Seng Gan

 Smart city integrates the internet and information and communication technologies (ICT) to improve the quality of life of its citizens. Monitoring of urban activity becomes an important aspect in smart city platform that automates and activates follow-up actions to improves responses from municipal officers, reduce manpower deployment, and reduce costs. The quality of our urban acoustic is one of the most important conditions for a healthy living environment. There are now several research activities that have been carried out in research labs worldwide to tackle different critical issues in environmental acoustics, such as noise control measures; measuring environmental sound fields; environmental soundscaping; application of state-of-art techniques in virtual acoustics to environmental studies; and automate monitoring sound events. In this talk, I will describe some of the recent works that are being carried out in my lab using acoustic signal processing techniques and artificial Intelligence to help to solve some of the urban acoustic challenges and our deployment of these acoustic systems in smart city testbeds.
