Security Enhancement using Vectoring, Cryptography and Steganography

Secure transmission of data is one of the most challenging goals. Generally, users avoid the use of a secure channel due to its high cost. Various schemes have been proposed to solve this issue. Some of the schemes are based only on encryption or steganography alone, which is not able to provide the desired level of security in a modern scenario. In this work, a security scheme has been proposed to address the challenge of secure communication at a low cost in three phases: vectoring, cryptography, and steganography. The proposed scheme has a flexibility factor that allows for different levels of security and secrecy. Different types of messages require different levels (high/low) of security, considering the circumstantial robustness on demand. A high level of security ensures security against attacks from the attacker for sensitive information. Our proposed security scheme is capable of providing the required level of security with decreased complexity. The proposed scheme is of a dynamic nature, as per the requirement.
