Secure medical information exchange with reversible data hiding

Exchange of medical information between hospitals is an essential part for medical treatments. In addition, security issues relating to electronic exchanges of information should also be concerned to protect the patient´s privacy and to help the treatments. In cooperation with the Health Level seven (HL7) standard, we employ reversible data hiding to further assist reducing the human errors during the exchange of information delivery. Reversible data hiding has attracted more and more attention in both researches and applications. We consider hiding part of the HL7 information into medical images at the encoder, and at the decoder, both the original image and HL7 information can be perfectly recovered. Simulation results demonstrate the superiority over existing schemes, and the effectiveness for practical applications.
