SYSTEM ANALYSIS, DESIGN & METHODOLOGY
3.1 INTRODUCTION
Crystography is basically the adoption of two information hiding techniques and fusing them together in order to enhance data security. This concept is aim at intensifying security in instances in which data confidentiality is of utmost importance. This technique of data hiding enhances security since it involves the combination of two strong techniques. It would not only encrypt the data but also hide them in an unattractive body. The implementation of this technique in the health sector would protect any patient’s information and in the case such information gets into the wrong hands, it still of no use to the intruding party involved.

The outlined steps just shows a surface of the entire process involved in achieving this task. The steps would be divided into two phases. The first phase outlines the encryption and data hiding process while the second phase shows the steps involved in un-hiding and decrypting the record.
Phase One
Encryption and Data Hiding
The following are the steps involved in the encryption and data hiding process
1. The patient would be prompted to login. For a new user, he/she would have to register in order to gain access.
2. During the registration process, some necessary information would have to be provided. The registration form would include the details which would be present in the medical record, which would be stored in a database.
3. After registration, the patient would be redirected to the login page to view his or her profile. Sensitive information provided during the registration process would be subjected to the encryption and data hiding process.
4. The patient profile would display the encrypted data details but the plaintext can be viewed if the patient supplies the key to decrypt which would replace the encrypted data with the plain
