IntelCrypt: Data Vault with Customizable Encryption Techniques

TLDR

IntelCrypt is presented, a secure messaging platform designed to provide enhanced data protection through multiple security mechanisms that integrates End-to-End Encryption, biometric authentication, and image steganography to ensure confidentiality, integrity, and secure communication.

Abstract

Secure communication is a fundamental requirement in modern digital systems due to the increasing number of cyber

threats and privacy concerns. This paper presents IntelCrypt, a secure messaging platform designed to provide enhanced data

protection through multiple security mechanisms. The system integrates End-to-End Encryption (E2EE), biometric

authentication, and image steganography to ensure confidentiality, integrity, and secure communication. A hybrid cryptographic

model using AES-256-GCM and RSA-2048 is implemented to provide strong encryption and efficient key exchange. In addition,

Least Significant Bit (LSB) steganography is used to hide encrypted messages within digital images, enabling covert

communication without noticeable visual distortion. The system architecture is implemented using Flutter for the frontend and

Spring Boot for the backend, following a clean and scalable architecture. Experimental implementation demonstrates improved

security and performance for high-security communication environments
