Possibilities for investigations of 43 varieties of file formats (objects), joined in 10 groups; 89
information attacks, joined in 33 groups and 73 methods of compression, joined in 10 groups are described in the
paper. Experimental, expert, possible and real relations between attacks’ groups, method’ groups and objects’
groups are determined by means of matrix transformations and the respective maximum and potential sets are
defined. At the end assessments and conclusions for future investigation are proposed.
