- 2. INTRODUCTION Data Privacy has become one of the biggest concerns for both individuals and organizations. The huge growth in cloud storage utilization over the past year has made a big demand for an advanced technique and strong tools. This adds more pressure on cloud service providers to gain more trust. This paper surveys various privacy-preserving techniques in cloud computing. Now we are going to demonstrate on the most innovative and strongest techniques that researchers has figured out and tested so far. In Cloud Computing:
- 3. Cloud Computing as defined by NIST “ a model for enabling convenient, on demand network access to a shared pool of configurable computing resources. Eg: Networks, Servers, Storage, Applications. Over the years, cloud services have expanded more to catch the interests and demands of the users with less cost features of its services. Users of Cloud like : Normal Individuals , Big Expanding Companies, Governments are all interested in the modern magic of safeguarding knowledge and information. Cloud Computing:

- 5. In cloud environment, data must be kept secure and safe. In today’s world there exist a lot of third-party cloud computing service and support providers of data, administration for processes, and much more of various needed services in the field. Their services yet are not just profitable, but offers even more vulnerabilities to cloud platform. Cloud computing systems permit users to execute calculations on a massive quantity of data without building a whole groundwork from scratch. Sending user’s data to the cloud server in the form of plaintext may endanger it to complete disclosure of data. Data Breach in Cloud Services:
- 6. METHODOLOGY One of the mechanism to protect data is hiding data by using specific calculations and algorithms. Figure 1: Privacy Preserving Techniques.
- 7. We are discussing three current privacy preservation techniques, which are most fascinating. 1. L-EnCDB Scheme • L-EnCDB is a novel lightweight encryption mechanism for databases. • This encryption method is using a format preserving encryption (FPE) scheme proposed with the L-EnCDB. • Secret and confidential data are generally encrypted before publishing to clouds for security necessities. • This results in a huge demand in practical operational databases. • Authors proposed this technique by addressing the following results: The technique supports practical SQL-based queries. Maintaining database structure. Major Privacy Preserving Techniques:
- 8. The traditional methods of applying security to data used to be by encrypting data with techniques such as : public key encryption, and symmetric key encryption Yet they change data types which makes it difficult to use them in database applications for several operations in SQL such as queries. Data extracted through queries cannot be protected if traditional encryption techniques do not meet the desired measures. This gives data owners a mission to both secure data and send them in a changeable form. This is why L-EnCDB scheme was suggested. It proposes a trivial encrypted database method signified by L-EncDB This method promises to achieve the necessities discussed beforehand, which are securing data without changing their format in a database.
- 9. L-EncDB can be successfully executed by using (FPE) technique and character string scheme, this way a data format can be preserved while in cipher text form. FPE enchances security in databases, its mission is to create a cipher text.
- 10. There are two layers in this system: • The first layer is the application system layer where several encryption methods (FPE,FQE,OPE) are used in several SQL queries, • And the interface installed in the database will perform SQL analysis, encrypt, and create cipher texts. • While the second layer is a database layer which is responsible for permitting developers to only perform SQL related functions, and also offer data services. L-EncDB layers:
- 11. Security concepts: SQL analysis interface is installed at the application layer or user’s side of the system. In this system there is expected to be a way to secure the key used in this encryption method. Two kind of adversaries that can used with the system’s security: • Those who target the database, with an attack to encrypted data and a database structure. • Adversaries who target both the database and system’s applications.
- 12. Three SQL operations on cloud:
- 13. L-EncDB is believed to be more practical supporting fuzzy queries in SQL. It offers a lighter and easier way to perform operations over data and sharing data securely to cloud providers. It guarantees privacy preserving for queried data from the database, which means securing valuable data when linking the database to the cloud. L-EncDB is suggested as an innovative technique that assures security and privacy preserving measures for data on cloud databases. Making the technique extra efficient it will be going under more examinations.
- 14. In summary, here are some points and remarks regarding every method and some noticeable highlights, addressed in the following table: Results:
- 15. Conclusion: This paper describes the importance of data security and why we need privacy preserving techniques in cloud computing. The paper discusses different surveyed privacy preserving techniques proposed by researchers. Summary of the three important techniques are discussed. The cloud computing field is improving and offering several solutions to serve this goal privacy preserving. We believe that this paper will help whom ever has the need to improve further techniques in the privacy preserving field, to enhance a better yet stronger approaches.
