Study of the Information Security of File Objects under Information Attacks with a Record of Effect of the Methods of Compression

摘要

This report examines important issues pertaining to the different ways of affecting the information security of file objects under information attacks through methods of compression. Accordingly, the reportanalyzes the three-way relationships which may exist among a selected setof attacks, methods and objects. Thus, a methodology is proposed for evaluation of information security, and a coefficient of information security is created. With respects to this coefficient, using different criteria and methods for evaluation and selection of alternatives, the lowest-risk methods ofcompression are selected.
