Question

Consider a color image of size 1000 x 1000, where each pixel is stored in 24-bits (containing red, green and blue components as 8-bits each). How many bytes of information can be hidden in the image by using single-LSB steganography technique?

 a. 3,75,000

 b. 3,000,000

 c. 1,25,000

 d. None of these.

​

Answer 1

Answer:

answer is 375000

Explanation:

Each pixel consists of 24 bits or 3 bytes, and hence 3 bits of information can be

stored in each pixel. The number of bits of hidden information that can be stored in the whole

image will be 1000 x 1000 x 3 bits = 1000 x 1000 x 3 / 8 bytes = 375000 bytes. The correct
