    The term “cloud computing” has been in the spotlights of IT specialists due to its potential of transforming computer industry. Unfortunately, there are still some challenges to be resolved and the security aspects in the cloud based computing environment remain at the core of interest. The goal of our work is to identify the main security issues of cloud computing and to present approaches to secure clouds. Our research also focuses on data and storage security layers. As a result, we found out that the protection of cloud data lies in cloud cryptography. Thus, this thesis reviews the new cryptographic techniques used to protect and process encrypted data in a remote cloud storage. In this thesis we are proposing a cryptographic scheme which uses fingerprint scanning for user authentication and AES technique of 128/192/256 bit cipher key for encryption and decryption of user's data. AES provides higher data security compared to other encryption techniques like DES and Blowfish. Our scheme is used in DropBoxCrypt application. DropBoxCrypt is a data encryption-decryption application developed for Android mobile devices which can be used for browsing, exporting and opening encrypted data stored in cloud storage.
