The increasing popularity of mobile cloud computing among mobile device users has allowed their data to be stored in cloud. When sensitive information is stored and transmitted on the Internet, security is the main issue. So user must have to ensure that the data is secure and protected. This article include the discussion of Data privacy to reduce data usage. In addition, mobile cloud computing has limitations in the following aspects resources, such as energy, processors, memory, and storage. Cryptography can ensure confidentiality, authentication, availability and data integrity. This is done through encryption algorithms, such as Data Encryption Standard (DES), Blowfish and Advanced Encryption Standard (AES). Experimental results and the performance of encryption algorithms is evaluated and compared. The performance indicators used are Encryption and Decryption time, CPU and memory utilization. The evaluation result shows to choose a suitable encryption algorithm among all technologies to reduce resources and consider the different parameters that are most suitable for future user requirements.
