End-to-End Data Security for Multi-Tenant Cloud Environment
Abstract: AbstractThis paper details the construction of a functional model that ensures data kept encrypted; while being processed in a multi-tenanted cloud environment. This can be done using homomorphic encryption only though the approach lacks in ability to search large databases. In a multi-tenant cloud environment, data is stored on several distinct data centers. As the request is encrypted, the server can't come up with exact match, so it would probably …

Speech Hiding in a Digital Image using DWT and DES Algorithm
Abstract: AbstractThe proposed paper presents a speech hiding technique in a digital image (DI). Here the technique used is Discrete Wavelet Transform (DWT). It secures speech signal from unauthorized users. It can be done by embedding speech into an image by steganography. Thus, unauthorized users will not detect secret speech in stego image. Suppose unauthorized users detect the speech that will be fraud because no one can obtain speech signal without …

Homomorphic Encryption Property Algorithms
Abstract: The demand for privacy of digital data increased over the last decade. The new invention in cryptography world is Homomorphic Encryption (HE). HE enables operation on cipher text without knowing the plaintext and private key. When receiver decrypts the result of any operation, it is the same as if the receiver carried out the calculation on the plain text. HE has some specific property. There are two properties in homomorphic …

Data Privacy in AI: Securing the Sensitive Information Through Homomorphic Encryption
Abstract: Artificial intelligence (AI) technology increasingly relies on sensitive user data, particularly finance and healthcare. While legacy encryption technologies safeguard data in transit and at rest, they are of no use when data must be decrypted to be processed. This is a bleak privacy threat, particularly in AI applications that call for constant processing of data. The objective of this study is to apply homomorphic encryption, a feature in which operations …
