A Novel Solution of Image Steganography with Encrypted QR Codes

Abstract

In secretive communication, steganography is extremely significant. Steganography is the
skill of concealing information in such a way that it is impossible to identify
concealed communications. To embed secret information in digital photographs, a
multitude of ways are available, but the Least Significant Bit (LSB) approach is the most
often employed. Preserving imperceptibility, nevertheless, remains a serious challenge.
Nonetheless, in today's world, retrieval of hidden communication by a third party is
achievable. Based on LSB, any type of message can be stored in the cover picture. One key
issue is that due to the prior approaches message is only partially obscured, it may be
retrieved by another person. The effort entails integrating Steganography for photos to
increase image security as well as image quality. This study describes a new steganography
approach that uses the RSA encryption procedure to produce encrypted QR data and LSB to
embed the image. Deploying an RSA-based QR-code data input pattern picture as well as the
LSB approach in the desired image, the procedure is developing the steganography
procedure. By splitting the secret message into a series of segments of equal length, stegoimage
pixels are detected by LSB which are matched to each segment (number of characters).
The experimental results show that the suggested approach improves the quality of stego
images over existing traditional data concealing procedures.
