Data deduplication and encryption are two important techniques that can be used together to enhance the security of cloud data transactions.
Data deduplication is a process that eliminates duplicate copies of data, reducing the amount of storage space required. This is done by identifying and removing redundant copies of data, leaving only one unique instance. In the context of cloud data transactions, this can reduce the amount of data that needs to be transmitted, which can improve the performance and security of the transaction.
Encryption is a technique that is used to secure data by converting it into a code that can only be deciphered by someone who has the correct key. In the context of cloud data transactions, encryption can be used to protect data while it is in transit and while it is at rest. This ensures that even if the data is intercepted, it will be unreadable without the correct key.
Together, data deduplication and encryption can provide a strong level of security for cloud data transactions. By reducing the amount of data that needs to be transmitted and encrypting it, these techniques can make it much more difficult for unauthorized individuals to access or modify the data.
Advanced technologies offer new opportunities to Cloud computing technologies. It provides computing power and storage resources in distributed environment, while abstracting underlying infrastructure, depending on a given service. Therefore, the usage and importance of cloud-based solutions will increase significantly in time to come. However, in some cases of collaborative research and data sharing process and storage of sensitive data, which is considered as private information and should not be shared without consent (for example patient's regarding his heath consent in healthcare).
Lack of standardization, with regard to access to cloud services, decreases then interoperability and flexibility of switching among CSPs. Hence, organizations may experience vendor lock-in, if unwilling to put in significant effort to accommodate their existing solutions to the new CSP. Access control systems should be reviewed and tailored for the suitability with dynamic and distributed nature of the cloud environment. Wide variety of user cases and imperfections in developing cloud technologies and standards make the aforementioned tasks even more complex and hard to realize in a unified way.
