Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography Abstract This paper proposes a lossless, a reversible, and a combined data hiding schemes for ciphertext images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless scheme, the ciphertext pixels are replaced with new values to embed the additional […]

Comments Off on SecRBAC: Secure data in the Clouds
Posted in: IEEE 2017, Java
Secrbac: Secure Data In The Clouds Abstract Most current security solutions are based on perimeter security. However, Cloud computing breaks the organization perimeters. When data resides in the Cloud, they reside outside the organizational bounds. This leads users to a loos of control over their data and raises reasonable security concerns that slow down the adoption of Cloud computing. Is the Cloud service provider accessing the data? […]
