− A stego image is an image with a hidden message.Stego-Key - Messages can be embedded in cover images and stego-images with the help of a key, or the messages can be derived from the photos themselves.3. Audio Steganography − It is the science of hiding data in sound. Used digitally, it protects against unauthorized reproduction. Watermarking is a technique that encrypts one piece of data (the message) within another (the "carrier"). Its typical uses involve media playback, primarily audio clips.4. Video Steganography − Video steganography is a method of secretly embedding data or other files within a video file on a computer. Video (a collection of still images) can function as the "carrier" in this scheme. Discrete cosine transform (DCT) is commonly used to insert values that can be used to hide the data in each image in the video, which is undetectable to the naked eye. Video steganography typically employs the following file formats: H.264, MP4, MPEG, and AVI.5. Network or Protocol Steganography − It involves concealing data by using a network protocol like TCP, UDP, ICMP, IP, etc., as a cover object. Steganography can be used in the case of covert channels, which occur in the OSI layer network model.Steganography Examples IncludeWriting with invisible inkEmbedding text in a picture (like an artist hiding their initials in a painting they’ve done)Backward masking a message in an audio file (remember those stories of evil messages recorded backward on rock and roll records?)Concealing information in either metadata or within a file headerHiding an image in a video, viewable only if the video is played at a particular frame rateEmbedding a secret message in either the green, blue, or red channels of an RRB imageSteganography can be used both for constructive and destructive purposes. For example, education and business institutions, intelligence agencies, the military, and certified ethical hackers use steganography to embed confidential messages and information in plain sight.On the other hand, criminal hackers use steganography to corrupt data files or hide malware in otherwise innocent documents. For example, attackers can use BASH and PowerShell scripts to launch automated attacks, embedding scripts in Word and Excel documents. When a poor, unsuspecting user clocks one of those documents open, they activate the secret, hidden script, and chaos ensues. This process is a favored ransomware delivery method.Steganography has a huge advantage over standard cryptographic methods. When someone uses cryptography, they’re passively calling attention

In the best watermarking tools, but you can read more about steganography here.Does it offer resizing and formatting tools?In many workflows, the final stage of the sharing process is watermarking for sharing. You generally don’t want need to watermark your source files, and you usually don’t want to upload images in full resolution, so it can be useful to have your watermarking software actually handle the process of reformatting your images to the proper size for uploading.Does it handle multiple file types?When you’re making digital images, JPEG is the most common format by far – but it’s not the only format. GIF and PNG are also common on the web, and TIFF files are often used for high-resolution image work. The best watermarking tools will support a wide range of the most common image formats, instead of forcing you to choose from a limited set of options.Final ThoughtsIt’s a wonderful world for photographers and image creators of all kinds, thanks to the sharing power of the internet. But since not everyone is as honest as we might like, it’s essential to watermark your images to make sure you get credit for them. There’s nothing worse than finally having an image go viral only to find out that you’re not getting the proper credit for your own work!Hopefully, these reviews have helped you to choose the best watermarking software for your specific situation – so get your work out there and share your images with the world!
