Abstract
Secret-Fragment-Visible Mosaic Image Transmission (SFVM IT) is a technique for securely transmitting confidential images. It offers an alternative to traditional methods like encryption, which can draw suspicion due to the scrambled data. SFVM IT disguises the secret image within another image, called a carrier image. Here’s how it works: The secret image is  divided  into small fragments. These fragments are then incorporated into the carrier image by modifying their color characteristics to match those of corresponding blocks in the carrier image. This creates a new image, the secret- fragment-visible mosaic image, that appears similar to the carrier image. Importantly, the transformation is designed to be reversible, allowing for the  extraction of  the original secret image latter’s IT offers several advantages. First, it  conceals  the existence of the secret image, making it less susceptible to interception. Second, the mosaic image appears natural, reducing suspicion during transmission. Finally, the technique allows for near-lossless recovery of the secret image at the receiving end, ensuring data integrity. Researchers are actively exploring ways to improve SFVM IT. This includes using different color models for transformation,  applying  genetic algorithms to optimize the mosaic image creation process, and integrating data hidi ng techniques for additional security. Overall, SFVM IT is a promising approach for secure image transmission in various applications where confidentiality is paramount.
