Steganography, not stenography, is a technique used in modern computer communications. Steganography is the practice of concealing information within other digital content, such as images, audio files, or text, in order to hide its existence. It is often used to ensure secure and covert communication between parties.
In modern computer communications, steganography can be employed in various ways:
1. Image Steganography: This involves hiding information within the pixels of an image. The hidden data can be embedded by slightly modifying the color values of certain pixels, which is usually imperceptible to the human eye. The recipient can then extract the hidden information from the image.
2. Audio Steganography: Similar to image steganography, audio files can be used as carriers to hide information. By manipulating the least significant bits of the audio samples, data can be concealed within the audio file. The changes are typically undetectable to the human ear.
3. Text Steganography: Concealing information within text is another method of steganography. This can be done by altering the formatting, spacing, or punctuation of a text document. The hidden data can be extracted by the recipient using specific techniques or tools.
4. Network Steganography: In computer networks, steganography can be used to hide information within network protocols or data packets. By modifying certain fields or using specific encoding techniques, data can be concealed within the network traffic, making it difficult to detect or intercept.
The purpose of using steganography in modern computer communications is to ensure confidentiality and secrecy. By hiding information within seemingly innocuous digital content, it becomes harder for unauthorized individuals or systems to detect or intercept the hidden data. Steganography can be used for various purposes, including covert communication, digital watermarking, copyright protection, and even as a means of cyber-attacks or espionage.
