Security and privacy are major concerns in this modern world. Medical documentation of patient data needs to be transmitted between hospitals for medical experts opinions on critical cases and sharing among chains of hospitals to make the patient’s data available which may cause delay and threats to the data. Nowadays most of the hospitals use electronic methods to store and transmit data with basic security measures, but these methods are still vulnerable. There is no perfect solution that solves all the problems in any industry, especially healthcare. So, to cope with the arising need to increase the security of the data from being identified and manipulated the proposed method uses a hybrid image encryption technique to hide the data in an image so it becomes difficult to sense the presence of data in the image while transmission. It combines Least Significant Bit Algorithm using Arithmetic Division Operation along with Canny edge detection algorithm to embed the patient data in medical images. The image is subsequently encrypted using keys of six different chaotic maps sequentially using XOR operation to improve reliability by preventing intrusion. The encrypted image is further converted into DNA sequence using DNA encoding rule and compressed using Bz2 algorithm.
