With the acceleration of digitalization, intelligence and networking, information science and computer technology will play an increasingly important role in various fields.This includes the current hot topics of Artificial Intelligence and Machine Learning, Cloud Computing and Big Data, Internet of Things and Edge Computing, Blockchain and Cryptography. ISCTT focuses on information science and computer technology, and in addition to covering some of the technologies in these hot research areas, we also focus on data security. In addition, the conference is based on information science and computer technology, and will also explore the application of these technologies in the direction of intelligent transportation. We hope that interested scholars can take advantage of such a professional communication platform to share some research results, provide new inspirations for scientific research, and promote new industry-university-research cooperation programs.
