“…In 2017 we proposed an LSB-based RDH method (Mondal et al, 2017) and the experimental results shows better efficiency than Zhang (2011), Hong et al (2012), and Qin and Zhang (2015). This scheme follows the same basic framework as of Zhang (2011) and the encryption and embedding procedures are of same nature.…”

Digitisation of sensitive images demands a lossless security mechanism and a sophisticated privacy preservation technique. Sensitive imagery, e.g., medical, forensic, military images, etc., needs special care during transmission as a little distortion can lead to catastrophic diagnosis mistake. With immense advancements, popularity, and success of service-oriented architecture (SOA), providing safe and secure online medical facility is one hard challenge for both research community and the industry. This paper proposes a 3-layer embedding mechanism enabled reversible data hiding (RDH) scheme with additional electronic patient record (EPR) hiding technique for encrypted medical images. LSB modification and LSB substitution technique are used for the embedding and EPR hiding. The experiments carried out on the medical test images on three levels of embedding and the experimental results show great potential in terms of security, embedding capacity, and recovered image quality.
