Abstract: Steganography is a powerful technique for embedding hidden information within digital media. This paper focuses on a web-based tool for encoding and decoding hidden text within images using steganography. The primary objective is to provide an intuitive platform for secure communication by concealing sensitive information in the alpha channel of image pixels, ensuring that the modifications are imperceptible to the human eye. The encoding process begins by encrypting the input text with a user-provided password using the AES encryption algorithm. The encrypted text is then embedded into the alpha channel of the image’s pixel data, with the length of the text stored in a specific pixel for retrieval during decoding. On the decoding side, the tool extracts the encrypted data from the image, decrypts it with the provided password, and displays the original text. To enhance usability and transparency, the system features a visualization mode that highlights the modified pixels, offering insight into the steganographic process. The paper is implemented using HTML5, JavaScript, and the CryptoJS library for encryption. It features a user-friendly interface for selecting images, entering text, and providing encryption passwords. Additionally, the tool ensures data security by combining encryption with steganography, making it suitable for applications requiring confidential communication or watermarking. This paper demonstrates the integration of cryptographic principles and steganographic techniques, providing a simple yet robust solution for secure data embedding.
