| dc.description.abstract | The introduction of cryptography has brought plenty of improvement to health informatics, but not really employed in health institutes and this is often as a results of the protection issues that come together with the employment of e-Health systems. Security issues is taken into account a significant concern which is why health institutes still opt to follow the normal way of addressing health records. This study aim to ensure data security in health record using enhanced Ceasar Cipher, Affine Cipher and Red2 Cryptographic Techniques.This method used is considered a double enhanced encryption algorithm with a steganography technique because it combines an enhanced Ceasar encryption method with Affine Cipher encryption technique to enhance security of medical health records along with Red2 algorithm, which helps encrypt cipher-text messages and hide them in images. The integration of the enhanced Caesar and affine ciphers is as follows: First, each field in the record is encrypted with the enhanced Caesar cipher encryption method, and the encrypted output is used as the input for the affine cipher encryption method after-which the output of the second encryption phase is fed into the steganography stage and the final output of the developed system is presented as an image.The result of this study is presented as a software solution and also some metrics like accuracy, precision, recall and F1-score were measure to test the performance of the system and it shows that the enhanced ceasar cipher encryption technique used in this study has a larger computational time which compensate for the high level of security and also the image used for steganography resulted to having lesser image quality parameters as this also compensate for the addition security level. In conclusion, the main aim of cryptographic system and steganographic system is to protect the confidentiality of data both at rest and in transit. With the mix of the enhanced Ceasar Cipher method and Affine cipher alongside Red2 Algorithm, these techniques has helped to enhance effectiveness.
