Abstract
Development of a method for protecting confidential files in a messenger based on an adaptive authentication system and blocking abnormal activity
Incoming article date: 14.09.2025The article discusses the development of a method for protecting confidential images in instant messengers based on masking with orthogonal matrices. The vulnerability of the system to brute-force attacks and account compromise is analyzed. The main focus is on the development of an architecture for analyzing abnormal activity and adaptive authentication. The article presents a system structure with independent security components that provide blocking based on brute-force attacks and flexible session management. The interaction of the modules within a unified security system is described, with the distribution of functions between server and client components.
Keywords: information security, messenger, messaging, communications, instant messaging systems, security audits, and brute-force attacks
