Foster Multidisciplinary Approach

This frontier project tackles many of the fundamental research challenges necessary to provide trustworthy information systems for health and wellness, as sensitive information and health-related tasks are increasingly pushed into mobile devices and cloud-based services.

How does the average user cope with the threats they encounter while engaged in the most sensitive of all online activities, online banking? Online Safety for the Ages (OSA) examines generational differences in motivations to use risky online services and self-protective measures in the context of online banking. An influx of older adults attracted to the Internet by social media but at times unfamiliar with dealing with the hazards of online life, as well as younger users who are sometimes oblivious to those dangers, pose distinct challenges to the preservation of online safety.

The security and integrity of elections is paramount in the furtherance of democracy. However, enhanced security often comes at the cost of making voting systems significantly more difficult for voters to use. With input from stakeholders in the voting process (most notably Travis County, Texas), we are constructing a prototype voting system and investigating how to design such a system so that it is significantly more secure than current solutions, without making it harder to participate in the election process.

The availability of ideal randomness is a common assumption used not only in cryptography, but in many other areas of computer science, and engineering in general. Unfortunately, in many situations this assumption is highly unrealistic, and cryptographic systems have to be built based on imperfect sources of randomness. Motivated by these considerations, this project will investigate the validity of this assumption and consider several important scenarios where secure cryptographic systems must be built based on various kinds of imperfect randomness.

Considerable research in the field has been focused on developing new technologies to enhance privacy; encryption of personal data is often presented as a potential solution. Many of the technologies resulting from this research are not being effectively utilized because of issues rooted in human judgment under risk and uncertainty. The majority of existing models and products related to human judgement are based on a limited number of documented incidents and on questionable assumptions about user intent and behavior.
