Privacy and Security: How to Differentiate Them Using Privacy-Security Tree (PST) Classification

Privacy and security have been discussed in many occasions and in most cases, the importance that these two aspects play on the information system domain are mentioned often. Many times, research is carried out on the individual information security or privacy measures where it is commonly regarded with the focus on the particular measure or both privacy and security are regarded as a whole subject. However, there have been no attempts at establishing a proper method in categorizing any form of objects of protection. Through the review done on this paper, we would like to investigate the relationship between privacy and security and form a break down the aspects of privacy and security in order to provide better understanding through determining if a measure or methodology is security, privacy oriented or both. We would recommend that in further research, a further refined formulation should be formed in order to carry out this determination process. As a result, we propose a Privacy-Security Tree (PST) in this paper that distinguishes the privacy from security measures.
