A Secure Memo for Mobile Application using Blowfish Encryption Technique
Abstract
Nowadays people are looking for a reliable and secure memo mobile application which avoid their data from being stolen. Mostly, people choose to back up their data in cloud storage which later can be accessible anywhere. However, the privacy of the data is at risk as the data also can be accessed by other party. In this study, the main objective is to develop a prototype of secure memo mobile application by applying Blowfish Encryption technique. This application was developed using Android Studio software and the data are stored in an online database called Firebase. The effectiveness of the prototype has been measured by benchmarking three (3) metrics: Response Time for encryption, Response Time for decryption and Memory Usage. Based on our findings, it proves that the system works effectively in terms of provides the fastest Response Time during encryption and decryption process and use only required a small portion in Memory Usage compared to Advanced Encryption Standard (AES) technique.
