Efficient Encrypted Images Filtering and Transform Coding with Walsh-Hadamard Transform and Parallelization

Since homomorphic encryption operations have high computational complexity, image applications based on homomorphic encryption are often time consuming, which makes them impractical. In this paper, we study efficient encrypted image applications with the encrypted domain Walsh-Hadamard transform (WH...
