So let's get started

What is Steganography?   Steganography is the art and science of embedding secret messages in a cover message in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message

As the image depicts, both cover file(X) and secret message(M) are fed into a steganographic encoder as an input Steganographic Encoder function, f(X, M, K) embeds the secret message into a cover file. The resulting Stego Object looks very similar to your cover file, with no visible changes This completes encoding. To retrieve the secret message, Stego Object is fed into Steganographic Decoder.

So, Steganography is the practice of concealing a secret message behind a normal message. It came from 2 Greek Word ⇒ steganos [covered] and graphia [writing]

Remember ⇒ Steganography and Cryptography ⇒ are two different concepts   Although both have the same goal ⇒ Protecting messages or information from the third parties

Cryptography changes the information to ciphertext which cannot be understood without a decryption key   On the other hand, steganography does not change the format of the information but it conceals the existence of the message.

Downside ⇒ The hidden message is easier to extract if the presence of secret is discovered     Steganography Techniques Steganography can be divided into five types: Text Steganography hiding information inside the text files Image Steganography Hiding the data by taking the cover object as the image Video Steganography the secret message is embedded into an audio signal which alters the binary sequence of the corresponding audio file. Audio Steganography can hide kinds of data into digital video format. Network Steganography embedding information within network control protocols used in data transmission such TCP, UDP, ICMP, etc                                 Best Tools to Perform Steganography Stegosuite is a free steganography tool that is written in Java. With Stegosuite you can easily hide confidential information in image files. Steghide is an open-source Steganography software that lets you hide a secret file in an image or audio file. Xiao Steganography is free software that can be used to hide data in BMP images or in WAV files. SSuite Picsel is another free portable application to hide text inside an image file but it takes a different approach when compared to other tools*.* OpenPuff is a professional steganographic tool where you can store files in image, audio, video, or flash files       So this is for today, Hope you like this post and check out our previous post - Digital Forensics in Cyber Security Social Engineering Attack Cryptography in Cyber Security Thanks for reading, To your success, Aman Yadav   #steganography #cybersecurity #cryptography #hacking #ethicalhacking #steganographie #python #cipher #kalilinux #thisiscle #momblogger #stemeducation #stemeducationforkids #stemblogger #stemactivity #clevelandbloggers #clemom #stemincleveland #stemprogramming #stemkindergarten #preschoolstem #elementarystem #stem #stemkids #stemforkids #steam #machinelearning #staycuriouscle #medicalimage #bhfyp #love #amansays
