CryptoStego app for iPhone and iPad

For hiding secret information in images, there exist a large variety of steganographic techniques,
some are more complex than others and all of them have respective strong and weak points. In the
proposed method, all pixels of the cover image can be used but message bit is stored in LSB of one
of the three color components, Red(R), Green (G), Blue (B) based on the parity of three LSBs of R, G
and B components of 24-bit color image. The proposed work uses the concept of parity method for
hiding and recovering secret data or information. The proposed method can hide large volume of
data in a single RGB image with changes in only few pixels of input image retaining the advantages
and discarding the disadvantages of traditional LSB method. We will combine algorithms of
cryptography and steganography to achieve multi-level security. A desktop application will be
developed, having option of using image steganography.

CryptoStego is the best image steganographiy application available for iOS appStore. Send messages without anyone knowing.

Steganography is the practice of hiding messages in plain sight. CryptoStego works all pixels of the cover image can be used but message bit is stored in LSB of one of the three color components, Red(R), Green (G), Blue (B) based on the parity of three LSBs of R, G and B components of 24-bit color image. The proposed work uses the concept of parity method for hiding and recovering secret data or information. The proposed method can hide large volume of data in a single RGB image with changes in only few pixels of input image retaining the advantages and discarding the disadvantages of traditional LSB method. We will combine algorithms of

AES-256 encryption is used for encryption technique. This encryption is incredibly hard to break, so rest assured your message will be safe if you choose to encrypt it.
