Uma abordagem para manter confidencialidade dos dados em nuvens de armazenamento

Abstract

Due to high utilization of information technology, a large amount of information are generated daily. Cloud computing emerges to keep this information with high availability and security. However, there are problems related to confidentiality of information stored in cloud storage environments, such as unauthorized access to user information and lack of use encryption in files stored in the cloud. Case the same are not properly protected, can be violated. To minimize the lack of confidentiality in cloud storage are necessary systems able to encrypt the user information before being sent to the storage cloud. In this work we proposed an approach that uses encryption techniques to keep files safely in the cloud storage servers. This is possible through the implementation of user file encryptions, before the files to be uploaded to the storage cloud. In the approach the user himself of service keeps the cryptographic key, which is used during the process of encryption and decryption through a mobile application, order to increase the level of data security. Thus , the application provides improvements in the confidentiality of the information stored in the cloud.
