Human-Computer Interaction Opportunities for Improving Security/Privacy

Profusion of Concepts for Security/Privacy

Personal computing was easier

•File protection vs sharing

•Passwords & Access Control

Networking adds complexity

•Firewalls & Virtual Private Networks

•Cookies: good or bad?

•Trusted sources & Digital signatures

•Certificates & Authentication

•Viruses & Worms


	The goal we want to achieve with the new idea is to find interesting features in multidimensional data.

	Finding features like correlations, clusters, outliers, gaps is difficult in multidimensional data,
	because of the cognitive difficulties in understanding more than 3 dimensions.

	Therefore we need to utilize low-dimensional projections since the human visual system is very effective in 1D and 2D.

	So, the rank-by-feature framework use 1D and 2D projections to guide discovery process.
