The seminar report on the LSB-based image steganographic technique is severely lacking in credibility and fails to provide a comprehensive analysis of its limitations.
Attacking LSB Based Image Steganographic Technique Seminar Report
Introduction
Steganography is the science of hiding secret information within an ordinary, non-secret, and digital cover medium in a way that does not allow the detection of the presence of secret information. LSB (Least Significant Bit) based image steganographic technique is one of the popular methods used to hide information in digital images. In this seminar report, we will discuss the existing system of LSB based image steganography, its drawbacks, and propose a new system to address these limitations.
Problem Statement
While LSB based image steganography is widely used for information hiding, it has several limitations that make it vulnerable to attacks. One of the main issues with LSB steganography is that the embedded information can be easily detected and extracted by malicious users using statistical analysis techniques. This poses a serious threat to the confidentiality of the hidden information. Therefore, there is a need for a more secure and robust steganographic technique that can protect the hidden information from detection.
Existing System
In the existing system of LSB based image steganography, the secret information is embedded in the least significant bits of the pixel values of the cover image. This technique is simple and easy to implement, but it is not secure enough to prevent detection. Attackers can use various steganalysis techniques such as histogram analysis, chi-square analysis, and RS analysis to detect the hidden information with high accuracy. This makes the existing system vulnerable to attacks and compromises the confidentiality of the hidden data.
Disadvantages
The disadvantages of the existing LSB based image steganographic technique include:
- Low security: The embedded information can be easily detected and extracted by attackers using steganalysis techniques.
- Poor robustness: The hidden information is vulnerable to loss or modification during image compression or editing.
- Limited capacity: The amount of information that can be hidden in LSBs is limited, which restricts the use of this technique for large data embedding.
Proposed System
To address the limitations of the existing system, we propose a new steganographic technique that enhances the security and robustness of hidden information. The proposed system will use advanced encryption algorithms to protect the embedded information and ensure that it remains confidential. Additionally, the new technique will increase the capacity of data embedding by utilizing higher order bits in the pixel values of the cover image.
Advantages
The advantages of the proposed system include:
- Enhanced security: The use of encryption algorithms will provide better protection for the hidden information against detection.
- Improved robustness: The hidden data will be less vulnerable to loss or modification during image processing.
- Increased capacity: The new technique will allow for larger data embedding by utilizing higher order bits.
Features
The key features of the proposed system are:
- Advanced encryption algorithms for improved security
- Increased data embedding capacity through the use of higher order bits
- Enhanced robustness against image compression and editing
- User-friendly interface for easy implementation and use
Conclusion
In conclusion, the existing LSB based image steganographic technique has several limitations that make it vulnerable to attacks. To overcome these issues, we have proposed a new steganographic system that enhances the security, robustness, and capacity of data embedding. The proposed system will provide better protection for hidden information and ensure its confidentiality. By implementing these improvements, we aim to develop a more secure and reliable steganographic technique for digital image hiding.
