information within other data, offers a covert method for hiding digital watermarks within images. In this paper, we utilize Least Significant Bit (LSB) steganography, a widely adopted technique that involves altering the least significant bits of pixel values in an image to embed hidden information. LSB steganography provides a balance between imperceptibility and robustness, making it suitable for embedding digital watermarks while minimizing visual degradation.
to hide information within digital media to prove authenticity or ownership. This research paper presents a method to embed a digital watermark within an image using steganography, along with encryption for enhanced security. The proposed system utilizes Least Significant Bit (LSB) steganography techniques and various hash algorithms for encryption, implemented through a combination of HTML, CSS, PHP, and Python languages. The system consists of two main parts: embedding the watermark into the image and decoding the embedded watermark. The embedded watermark is encrypted using selected hash algorithms before being embedded into the image. Upon decoding, the system compares the decrypted watermark with the original one to verify integrity. The application areas of this project include image tracking, digital forensics, and copyright protection.
1.2 Encryption: In addition to steganography, encryption plays a crucial role in enhancing the security of embedded digital watermarks. Encryption algorithms such as MD5, SHA-256, and Base-64 are employed to encrypt the digital watermark before embedding it into the image. This encryption adds an extra layer of security, ensuring that the embedded watermark remains confidential and tamper-resistant. By encrypting the watermark before embedding, the system mitigates the risk of unauthorized access and tampering.

1.3 System Architecture: The proposed system architecture comprises a combination of HTML, CSS, PHP, and Python languages to facilitate the embedding and decoding of digital watermarks within images. The system consists of two main stages: watermark embedding and watermark decoding. During watermark embedding, the original image and selected watermark undergo encryption using chosen hash algorithms through PHP. Subsequently, a Python script performs LSB embedding, hiding the encrypted watermark within the image. On the other hand, during watermark decoding, the embedded watermark is extracted from the image using Python, decrypted using PHP, and compared with the original watermark to verify integrity.
1. INTRODUCTION Digital watermarking has emerged as a crucial technique for securing digital media and proving ownership. This paper presents a novel approach to hide a digital watermark within an image using steganography techniques, with an added layer of security through encryption. The system aims to ensure the integrity and authenticity of digital images, thereby serving various applications in image tracking, digital forensics, and copyright protection. Digital watermarking traditionally involves embedding information directly into digital media, often in a manner that is detectable or manipulable. However, such conventional methods may not provide adequate protection against malicious tampering or unauthorized access. To address these challenges, this paper proposes the integration of steganography with encryption, offering a covert and secure means of embedding digital watermarks within images.
