Abstract

Securing image information has become a key concern with the rapid development of digital data transmission and storage. With the increasing use of images and videos in various fields such as social media, defense, and surveillance systems, it is important to protect personal and sensitive image data from unauthorized access. Image security has thus become a critical challenge. Protecting important and personal images is essential, and many methods have been investigated and developed to preserve data and private information. Among them, image encryption is one of the most widely used techniques to secure image data from unauthorized access. In this paper, an image encryption approach based on pixel value rotation and text file creation is proposed. First, the image size and image name are extracted. Then, the pixel values of each component (R, G, B) are obtained and rotated by a certain number of times. Finally, the rotated pixel values (R, G, B) are stored in a text file. Experiments have been conducted on various sets of images to validate the method.

Keywords: Encryption, Decryption, Rotation, Extraction, Password.
