Intelligence and Security Informatics (ISI) research is an interdisciplinary research field involving academic researchers in information technology, social and behavioral sciences, computer science, law, and public policy. It also includes industry consultants, practitioners, security managers, and chief information security officers (CISOs) that support physical and cyber security missions at the individual, organizational, national, and international levels, including anticipation, interdiction, prevention, preparedness, and response to threats. The annual IEEE International Conference on ISI (IEEE ISI) was started in 2003 in Tucson, Arizona. Since then, the conference has been hosted in Atlanta, San Diego, New Brunswick, Taipei, Dallas, Vancouver, Beijing, Seattle, Washington DC, the Hague, Baltimore, Tucson, Beijing, and Shenzhen. Over the past 18 years, the IEEE ISI Conference has evolved from its traditional orientation towards the intelligence and security domain towards a more integrated alignment of multiple domains, including technology, humans, organizations, and security. The scientific community has increasingly recognized the need to address intelligence and security threats by understanding the interrelationships between these different components and integrating recent advances from different domains. This year, the IEEE ISI conference will be held in San Antonio, Texas. http://www.isi-conf.org/ IMPORTANT DATES: Submission Deadline: August 7, 2021 Notification of Acceptance to Authors: October 1, 2021 Camera-ready Deadline: October 15, 2021​ Early-Bird Conference Registration: August 31, 2021 Conference: November 2-3, 2021 Topics: We invite academic researchers in the field of Intelligence and Security Informatics and related areas as well as IT, security, and analytics professionals, intelligence experts, and industry consultants and practitioners in the field to submit papers and workshop proposals. ISI 2021 submissions may include empirical, behavioral, systems, methodology, test-bed, modeling, evaluation, and policy papers. Research should be relevant to informatics, organizations, public policy, or human behavior in applications of security or protection of local/national/international security in the physical world, cyber-physical systems, and/or cyberspace.

Each manuscript must clearly articulate their data (e.g., key metadata, statistical properties, etc.), analytical procedures (e.g., representations, algorithm details, etc.), and evaluation set up and results (e.g., performance metrics, statistical tests, case studies, etc.). Making data, code, and processes publicly available to facilitate scientific reproducibility is not required, but is strongly encouraged. We accept three types of paper submissions on proposed tracks and related topics: long paper (maximum of 6 pages), short paper (maximum of 3 pages), and poster (1 page). The submission format is PDF. The accepted paper will be presented by an IEEE member. Consult the IEEE publications page at https://www.ieee.org/conferences/publishing/templates.html for formatting information. Papers will be submitted through the EasyChair submission and review system. The Call for Papers and submission links are at the end of this message. The accepted papers from ISI 2021 and its affiliated workshops will be published by the IEEE Press in formal proceedings. There will be a Best Paper Prize, Prize Amount TBD.
