# 3: Steganalysis

## Review: Image steganography
### Hiding data in spatial domain
1. LSB
### Hiding data in transform domain
1. Discrete Cosine Transform (DCT)
2. Discrete Wavelet Transform (DWT)

## Fundamentals

## Specific/Targeted steganalysis

## Blind/Universal steganalysis

# Lab
## 1 LSB Steganalysis in Spatial Domain

## 2 2-D Image Transforms (DCT)
