Enhanced EPR data protection using cryptography and digital watermarking
Youssef Zaz, Lhoussain El Fadil · 2011
In this paper, we propose a novel method to embed Electronic Patient Records (EPR) data in medical images. Indeed, after liberating a zone by compressing the image Least Significant Bit plan using the Huffman coding, the EPR is encrypted by an Elliptic Curve Cryptosystem (ECC) and inserted into this zone. The proposed method improves medical security performance and reduces the computation cost related to data encryption and decryption.
