SECURING PHARMACEUTICAL DATA USING HOMOMORPHIC ENCRYPTION

Abstract

In a time when effective data storage and access are essential to the operation of any application, 
cloud computing emerges as a key area of research in offering limitless storage and effective data 
access. However, cloud storage comes with a host of drawbacks, the most significant of which are 
related to user data security. In the current situation, the user is dependent on the third party—the 
company that provides cloud storage—to take the appropriate precautions to shield its clients' data 
from unwanted access and to maintain the client-company confidence that no improper handling or 
misuse of data will occur. The main emphasis of recent cloud computing research has been on 
developing and implementing cryptographic approaches that provide users control over the privacy of 
their data kept on cloud servers. One of the cryptographic methods that enables data modification in 
encrypted form without requiring decryption is homomorphic encryption. Homomorphic encryption 
may be used to reduce security breaches in the pharmaceutical industry, which is an industry with a 
high risk of them.
