Enhancing Medical Data Security by Image Steganography

Cyber and data security is a major concern to health care. The largest health care breach ever recorded exposed the personal records— including names birth dates Social Security numbers home addresses and other personal info. The average cost to health care organizations per record breached is $355 compared to $158 per lost or stolen record in other industries. So there is a need for a more secure way to store the medical data.Image steganography is being considered as an alternative method for securing medical data to avoid medical related cybercrimes. There are two images namely secret image and cover image. This method embeds secret image into cover image. Application of basic Huffman coding is mainly compressing the data without the loss of information.
