Abstract Data hiding is a noteworthy research topic in digital technology for years. Reversible data hiding (RDH) technique plays a vital role for confirming security of the digital transmissions. A new 2-layer secure, high capacity reversible data hiding technique has been proposed, using the concept of interpolation based data hiding and difference expansion method. Unlike, state-of-the art interpolation based RDH techniques, the security has been enhanced in the proposed technique by concealing the data into the image pixels in nonsequential manner. This technique offers high-capacity data hiding, by considering the maximum difference between neighboring pixels without compromising on quality of the images. It can embed up to 3.19 bpp in Baboon image which is better than the other existing state-of-the art interpolation based RDH (IRDH) techniques. The proposed technique is sustainable against the series of tests provided by standard StirMark Benchmark 4.0 analysis. It withstands the steganalysis attacks, viz., StegExpose as a measure of security. Keywords Reversible data hiding · Interpolation · Difference expansion · Steganography · Steganalysis

1 Introduction Data hiding [18, 19, 30] is the practice of hiding stealthy message into the digital media, that is grouped into steganography and watermarking, depending on the applications. Watermarking [17, 31] is used for copyright protection, while steganography is used for covert communication. Different kinds of cover media have been used for steganography, where the image steganography [5, 20, 24] is become the most widespread. The job of image steganography is to make little modification on the pixels to transmit necessary secret information. Reversible data hiding (RDH) [34, 36, 37, 40] techniques let the accurate retrieval of the original image after the recovery of the concealed message. Satellite communication, military, legal investigation and in medical images, reversibility is desirable with high accuracy. On the other hand, in irreversible [6, 38, 39] data hiding, original image is not retrieved from distorted image after extraction of the secret message. Interpolation based RDH [7, 16, 23, 29] techniques have gained much popularity over the years. In interpolation, a small image is scaled-up and known data estimates the values at
