Which method can investigators use to detect steganography?

Investigators can employ multiple methods to detect steganography, which is the practice of hiding data within other files, such as images, audio, or video. The most comprehensive approach to identifying hidden information utilizes all available techniques, as each contributes valuable information that can lead to the detection of steganography.

Visual checks for anomalies can reveal unexpected or unusual visual elements in images, such as inconsistencies in color patterns or pixel arrangements that may indicate hidden data. This method relies on the human ability to notice irregularities that may not be immediately apparent.

Determining statistical deviations in files involves analyzing the data for patterns that deviate from normal. For example, steganography often changes the statistical distribution of pixel values in an image or the frequency of certain sounds in audio files. By comparing these statistical measures to standard benchmarks, investigators can identify potential instances of steganography.

Examining files for structural oddities is crucial because steganographic methods often manipulate the inherent structure of files to hide information. This can involve changes in file headers, metadata, or the way data blocks are organized, which may signal that hidden content exists.

Using a combination of all these methods enables a more robust detection strategy. Each method addresses different aspects of potential steganography, allowing
