A Review of Cryptography Techniques for Securing Data on Messaging and Cloud Applications

Within a few years, the Internet has arrived at a level that is starting to affect every aspect of our lives in both good and bad ways. Information security has turned into a primary worry for anybody connected to the web because of repeated attacks and data leaks. Many files/data are getting uploaded/downloaded on the internet. However, securing such data/files has not been given much importance in the past as not many people were using the internet. There was less amount of sensitive data to attack and steal. Message encryption techniques have been used by various messaging service apps, but they also fail to secure files, emoji and stickers shared through these apps. Some people use the cloud to store and share their files but these cloud services have also been victims of data leaks. Therefore providing critical information to these 3rd party clouds is not the best solution. In this paper, we are analyzing the current encryption techniques used for secure files and message transfer with their advantages and disadvantages.The observations from this research signifies that the most common and used cryptography techniques are not sufficient to safeguard the files. Developers need to bring advanced techniques into the mainstream by implementing them in messaging apps and cloud servers. People should have a right to privacy and should be taught how to implement cryptography.
