As a Specialist in Video Encoding, I Aim to Create the Ultimate Video Imaging System Based on Photoelectron Information

Encoding technology, which effectively compresses the capacity of still images and videos, has developed into a cutting-edge research field, which is necessary in today's world to transmit vast amounts of information efficiently in a multimodal manner. Dr. Seishi Takamura, a visiting senior distinguished researcher at NTT Computer and Data Science Laboratories, is a world-renowned researcher in this field and has proposed a series of new encoding methods based on various ideas. Recently, he has been challenging himself to explore the ultimate video imaging system that captures, transmits, stores, and displays images at the level of photons, the smallest units of light that make up images. In this interview, we asked him about his latest research results, vision for the future, and perspective as an IEEE (Institute of Electrical and Electronic Engineers) Fellow on raising Japan's research capabilities and nurturing young researchers, including students.

Security Measures to Restore Reliability in the Open-source Software Supply Chain

The discovery of a backdoor in the open-source software (OSS) "liblzma" (a file-compression library) in 2024 demonstrated that even core operating-system libraries could be targeted in a manner that fundamentally damage the credibility of the OSS supply chain. Fortunately, this incident was discovered and addressed before it could be deployed to countless systems worldwide. In light of this serious situation, further strengthening of cybersecurity has become an urgent necessity. In this interview, we spoke with Distinguished Researcher Akihiro Suda at NTT Software Innovation Center [affiliation as of the time of the interview], a leading expert in strengthening the security of the OSS supply chain.
