Abstract - Image watermarking is an essential method in
programming languages. By examining their effectiveness for web applications and standalone processing, the study aims to shed light on how these languages can be leveraged for image protection in various contexts.
digital image processing, aimed at protecting IPR(intellectual property rights) and deterring unauthorized use of images. This paper tests and compares both visible and invisible implementations in PHP and Python, focusing on their effectiveness, ease of use, and performance. By providing practical code examples, this highlights how each language handles watermark embedding and extraction, emphasizing their respective advantages and disadvantages. PHP, often preferred for web-based applications, offers straightforward integration with web servers, for dynamic content. In other side, Python, known for its powerful libraries and ease of use, bests in standalone applications, providing flexibility for complex image processing tasks. This paper includes insights into best use cases for each approach, addressing scenarios where one language might be preferred over the other. This study serves as a controller for developers looking to implement watermarking solutions in different environments, ultimately contributing to enhanced protection of digital assets and intellectual property. By exploring these implementations, the paper tries to facilitate choices between PHP and Python for watermarking projects, with effective protection of images in the digital world.
1.1 Watermarking Techniques Watermarking is categorized into two main types: visible and invisible. Visible watermarking involves embedding text or logos directly onto an image, making the mark clearly visible to deter unauthorized use. This approach is effective for promoting ownership but can alter the viewer's experience of the image. In contrast, invisible watermarking hides information within the image itself, often utilizing frequency transformations such as Discrete Cosine Transform (DCT) or Discrete Wavelet Transform (DWT), as well as bitwise manipulation. This technique is commonly used for digital rights management and tracking image usage without affecting the image's visual quality, allowing for ownership protection while maintaining a seamless user experience. Steganography has a wide range of applications, from military and intelligence operations to digital watermarking and copyright protection (Image hiding by using spatial domain steganography, 2023). Digital Rights Management (DRM) technologies (also known as Electronic Rights Management System) ensure copyright through identifying and protecting the content controlling access of the work, protecting the integrity of the work and ensuring payment for the access. DRM technologies prevent illegal users in accessing the content, Access is protected through the user ID and password, licensing agreements. (Ansari, 2019).

1.INTRODUCTION In today’s digital landscape, images are easily shared and often repurposed without permission, making the protection of image ownership crucial for photographers, designers, and content creators. Watermarking, which involves embedding a mark to identify ownership, has emerged as an essential tool in safeguarding digital assets. Watermarking techniques can be categorized into visible and invisible methods, each offering unique applications and challenges. This paper investigates watermarking implementations in PHP and Python, comparing the capabilities and limitations of these widely used

2. PHP AND PYTHON IN IMAGE PROCESSING PHP is widely employed in server-side web applications, making it a practical choice for dynamically adding watermarks to user-uploaded images on websites. Its GD library provides basic image manipulation capabilities, allowing for straightforward implementation of visible watermarking. In contrast, Python has gained popularity in data science and machine learning due to its powerful libraries, such as Pillow (pillow · PyPI, n.d.) and OpenCV. These libraries offer robust image-processing capabilities
