When hiding data images, explain why it is better to uniformly disperse the hidden data throughout the file using a seeded pseudo-random number generator as well as disperse the data through the file, concentrating on edges and noisy areas. Please complete answer.
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator(DRBG),is an algorithm for generating a sequence of numbers whose properties approximates or matches the properties of sequences of random numbers. The PRNG’s-generated sequence is not truly random, because it is completely determined by an initial value, called the PRNG’s seed (which may have truely random values). Thus only by knowing the PRNG’s seed we can decrypt the data that is been hiding in the image.
The dispersed data is concentrated among the edges and noisy areas of the image because these areas consists of more fragments and the more fragments in a image the less chances of getting caught.Another reason is that these areas when scanned by decrypter or software did not provide the actual and precise information as they have complex structure and vibrant coloring schemes and the decrypting tools will not be able to crack the information.
