dc.description.abstractThe importance of data security is growing for companies trying to safeguard sensitive information. Cryptography and steganography are two widely used methods. Steganography enables the concealment of secret information within digital content to reduce suspicions. Even though the Least Significant Bit (LSB) technique is widely utilized, when applied alone, it is still vulnerable to security breaches. Traditional approaches that combine LSB steganography with RSA encryption enhance security but are computationally expensive, making them less useful for real-time applications like data storage, secure communication, and the Internet of Things. The need for a robust yet lightweight system that combines encryption and steganography without compromising performance is thus necessary. This study proposes a hybrid approach that blends LSB steganography with Elliptic Curve Cryptography (ECC). Because it uses less processing power and has lower key sizes than RSA, ECC was selected to maintain similar security standards. The method was implemented and evaluated in terms of encryption time, data-hiding capabilities, and efficiency. Experimental results show that the LSB–ECC framework outperforms the conventional LSB–RSA combination. Specifically, by significantly reducing encryption time and improving hiding efficiency, ECC offers a more scalable solution for safeguarding sensitive data. The findings confirm that ECC provides a lighter solution without sacrificing security. ECC's integration with LSB steganography exhibits exceptional efficiency and security performance, making it appropriate for contemporary data protection requirements. Adaptive steganographic approaches and testing on extensive multimedia datasets will be incorporated into future work to further validate robustness against sophisticated steganalysis and cryptographic attacks.
