Abstract
The paper proposed methods to protect secret information by encryption and hiding so as to conceal and protect medical data and records from being hacked. This is done through implementing two layers by using two method Elliptic curve cryptography and image steganography. First layer means first step encrypting the text through using ECC; then, the second layer is to hide the encrypted text inside the image by using 1-LSB and 2-LSB image steganography [25]. Selecting ECC, it constitutes an approach to cryptography of public key through relying on the algebraic structure of elliptic curves over finite fields, is considered as being a desired choice for being public key [13] [17]. Furthermore, it can be used in many type of media they use it in medical record system and in field such as X-Ray, CT scan, and MRI scan. Selecting Image Steganography, which is a technique to prevent the third person to have a look or detect easily the overlaying files, including the files that are encrypted [14]. Selecting the Least Significant Bit algorithm for steganography, it is commonly used straightforward steganographic algorithm and less complication. Testing two sorts of steganography (1-LSB and 2-LSB) to o find the difference between them and to clarify the positive negative aspects of each of them. The technique can be used by any person, group of persons or organization to hide and protect their important business information or nation's secrets, or laboratory secrets or the important defines information.
