What Is Multimodal Indexable Encryption Or MIE?

They addressed the SkNN problem under the following setting: the client has the ciphertexts of all data points in database T and the encryption function of T, whereas the server has the decryption function of T and some auxiliary information regarding each data point. Both methods [51, 98], however, are not secure because they are vulnerable to chosen-plaintext attacks. All the above methods also leak data access patterns to the server. Recently, Yao et al. [99] proposed a new SkNN method based on partition-based a Secure Voronoi Diagram (SVD). Instead of asking the cloud to retrieve the exact kNN, they required the cloud to retrieve a relevant encrypted partitionEpk(G) for Epk(T)such that G is guaranteed to contain the k-nearest neighbors of q. This work, however, solves the SkNN problem accurately by letting the cloud retrieve the exact k-Nearest Neighbors of q (in encrypted form). Additionally, most of the computations during the query processing step in [51, 99, 105] are performed locally by the end-user. That conflicts with the purpose of outsourcing the DataBase Management System (DBMS) functionalities to the cloud. Furthermore, the protocol in secure nearest neighbor revisited[99] leaks data access patterns, such

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

Encryption is a process of converting Plain text into Cipher text. This un-readable message can be communicated over an unsecure network without the fear of loss of integrity and confidentiality. Encryption process is done using encryption algorithm.

One of the prominent works to accelerate the search over encrypted keywords in the public-key setting is deterministic encryption introduced by Bellare et al. An encryption scheme is deterministic if the encryption algorithm is deterministic. Bellare et al. focus on enabling search over encrypted keywords to be as efficient as the search for unencrypted keywords, such that a ciphertext containing a given keyword can be retrieved in time complexity logarithmic in the total number of all ciphertexts. This is reasonable because the encrypted keywords can form a tree-like structure when stored according to their binary values. Search on encrypted data has been extensively investigated in recent years. From a cryptographic perspective, the existing works fall into two categories, i.e., symmetric searchable encryption and public-key searchable encryption.

Transmission of data from one place to another securely becomes a challenging issue in this highly technological era. Stealing the information becomes the full-time job of hackers. To send the data secretly, encryption algorithms are used. Many encryption techniques are evolving to protect the information being send. In this essay, two different encryption methods, Quantum Key Description and Honey Encryption were explained briefly. Also, this essay addresses their benefits and limitations and the areas in which the algorithms are used.

In today’s world information security is extremely important; this is due to the fact that everything in everyone’s daily life is somehow connected to the internet in one way or another. It is of the upmost importance that the information stored on servers throughout the world be protected at all times. Globally, people of all walks of life have personal information stored on servers, whether it be banking information, social media information, phone numbers, addresses, etc. all of this personal information must be secured. The basic concepts of securing data would lie within the CIA triad. The CIA Triad stands for confidentiality, integrity and accessibility. With confidentiality, this ensures that the data be encrypted and not made available to an unauthorized individual. Integrity of information means that the data be accurate and not allowed to be changed in any way without proper credentials, this ensures the data stays intact without mishandling or corruption. Lastly, accessibility is making sure the data can be retrieved by an authorized individual in a dependable and timely manner also, to ensure the information systems are reliable.

Personal health record (PHR) is a developing patient-centric model of health information exchange, which is often deployed to be archived at a third party, such as cloud service providers a person is concerned more about their health condition which is considered as most important and personal. At the same time in order to get cure from medical issues, Health bulletin is shared to the Specialists Doctors throughout the world due to the advancements in the Present day Technology. Few privacy issues may arise as personal health information could be disclosed to those third party servers and to illegitimate parties. Encrypting PHR’s before externalizing to let the patients have access to their own records is an effective way .This paper

Encrypt all data on mobile and remote computers/devices (e.g. laptops and/or desktops) that are used from outside an Department location to access or store high sensitive data to support normal business operations.

In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control [6], [7] is paramount as it is the first line of defense that prevents unauthorized access to the shared data. With the burgeoning of network technology and mobile terminal, online data sharing has become a new “pet”, such as Facebook, MySpace, and Badoo. Meanwhile, cloud is one of the most promising application platforms to solve the explosive expanding of data sharing. In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control is paramount that prevents unauthorized access to the shared data. Recently, attribute-based encryption (ABE) has been attracted

Cloud computing has become the most common phenomenon in the recent years. More and more cloud services have flourished all around the world such as computing resource, storage space outsourcing and different kinds of software applications. For many reasons like low cost, efficiency, convenience, better connectivity and etc., user often stores his data on remote servers. Since more servers are public, there exist a lot of risks for the data in the transition process, the user ensures the privacy of his data by storing it in encrypted form, then he can search the encrypted data and retrieve it. The first effort of searching encrypted data by keyword was tackled by Song, Wagner and Perrig cite{s1}. To securely search over encrypted data, searchable encryption schemes have been proposed in recent years cite{b2,b3,b5,c2,c4,g1,w2}, which can be divided into two schemes: symmetric searchable encryption (SSE) and asymmetric searchable encryption (ASE). To perform a search on a dataset, an user creates an index of keywords listed in the documents and later on executes the search on the index in a way that allows the server to retrieve the documents contain a certain keyword instead of retrieving all the encrypted documents back which is fully impractical solution in cloud computing scenarios. Recent refinements and extensions to this scheme are given in cite{g1, w2}.

Identity based encryption is an energizing distinct option for open key encryption, which takes out the requirement for a Public Key Infrastructure (PKI) that makes freely accessible the mapping between characters, public keys, and legitimacy of the latter. The senders utilizing an IBE don 't have to look up in public keys and the relating declarations of the collectors, in light of the fact that the personalities e.g. messages or IP addresses together with regular open parameters are adequate for encryption. The private keys of the users are given by a trustee outsider called the private key generator (PKG).

In the version of security analysis and experimental results our proposed encryption scheme is fast and on the other hand provides good security and adds very less overhead on the data, this today is the requirement of most of the multimedia applications.

Today web is going towards the multimedia data in which image covers the highest percentage of it. But with the ever-increasing growth of multimedia applications, security is an important aspect in communication and storage of images, and encryption is the way to ensure security [1]-[2]. Image encryption techniques try to convert original image to another image that is hard to understand and to keep the image confidential between users, in other word, it’s important that without decryption key no one can access the content. Image encryption has applications in internet communication,

Abstract— Data de-duplication is one of essential data com-pression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting de-duplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. The main motivation behind using this technique is making convergent encryption practical to capably and consistently manage a huge number of convergent keys and achieving competent and consistent key management in secure de-duplication. At we first introduce a baseline approach in which each user holds an independent master key for encrypting
