Based on our work on IDN homograph attack detection (preprint: https://arxiv.org/abs/1909.07539), we proposed to launch a community group named anti-homograph attack (AHA) at the W3C Technical Plenary and Advisory Committee Meetings (TPAC) held in Fukuoka, Japan. If you are interested in exploring the ways to detect possible IDN homographs efficiently, please join us. You can find the contact address at our github repository: https://github.com/yoneyajp/AHA/wiki or you can drop me an email: mori_at_nsl.cs.waseda.ac.jp
We will keep on working with the standardization communities such as W3C, ICANN, IETF, and Unicode consortium to make our research outcomes available in the real world.
