Minimizing security risks in ubicomp systems

In the Internet's early days, few people foresaw the emergence of spam, phishing schemes, and malware such as viruses, worms, Trojan horses, spyware, and key loggers that plague users today. It's safe to assume that ubicomp technologies will suffer from the same sorts of unforeseen vulnerabilities that have plagued the Internet. We can't account for every possible security and privacy risk in ubiquitous computing systems. We can, however, design such systems to reduce the burden on users as well as develop better security models and interaction techniques to prevent and minimize foreseeable threats.
