Human-Computer Interaction Opportunities for Improving Security/Privacy

Profusion of Concepts for Security/Privacy

Goals

•Availability: Accessible when needed

•Confidentiality: Crypto & limit access

•Data integrity: Prevent modifying your data

•Control: Access rights & physical security

•Audit: Logging, review & damage assessment

Most current systems present the user with an intricate interface for specifying his protection needs. The result is that the user has trouble figuring out how to make the specification and verifying that he requested the right thing. User interfaces that more closely match the mental models people have of information protection are needed.
Saltzer & Schroeder, 1975


	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.
