Abstract
The study was conducted in the field of hiding messages using the media image. This model is often referred to as steganography technique. Image media used for insertion are BMP (Bitmap Picture) format images, JPEG (Joint Photographic Expert Group) and PNG (Portable Network Graphics). The secret message form that is inserted is in the txt format. The application used for insertion is the Digital Invisible Ink Toolkit. Research parameters include image quality testing, and quantitative testing on each Blindhide algorithm and the Filterfirst algorithm. Image Quality test results using MSE, PSNR, showed significant differences, while the value of SC showed differences but not substantial. The results of testing and analysis evaluations that have been carried out on each image turned out to be an average value of the MSE value of the Blindhide algorithm 0.024 greater than the Filterfirst algorithm 0.023, PSNR Blindhide algorithm 31.91 smaller than the Filterfirst 32.03 algorithm, SC Blindhide algorithm 0.99986 smaller than the Filterfirst algorithm 0.99988. This shows that the insertion of a secret message into the image using the Filterfirst algorithm is safer and will not be suspected.
