Symmetric additive homomorphic encryption
WebWith the many benefits of cloud computing, an entity may want to outsource its data and their related analytics tasks to a cloud. When data are sensitive, it is in the interest of the entity to outsource encrypted data… WebWe propose separable inverted data hiding in an encrypted signal with public key coding. In our separable general, the image landlord encrypts the originally image by using a public key. On receiver of the encrypting signal, the data-hider embeds data in it by using ampere data-hiding key. The artist decipherment both data extraction are independent and separable at …
