The number of cyber crimes on changing the form of the original image results in losses to the victims concerned. This has become a serious problem for some people, especially for public figures. Based on these problems, we conduct research to implement cryptographic implementations on text messages in image media by combining cryptographic and steganographic methods using an edge detection algorithm based on Python programming. steganography method. This system is designed and tested with Image data types of various sizes, as well as testing the results of the watermarking process and the Scanning watermark process. The test results show that the application is better used for files with image data types .jpg and also pngfor files with image data types .jpg and also png
