The analysis of the current state in the field of subjects biometric identification is provided. The main methods of biometric identification, the process of features space formation used subsequently for decision-making on the subject's access to system resources, as well as new approaches to the use of biometric images for protection of data on electronic documents are considered. The new problem of identification of subject's changed state, and perspectives of using subjects' thermal images for the purpose of determining changed state, is discussed.
