11. Enhancing Privacy in Remote Data Classification.

Author

Piva, A., Orlandi, C., Caini, M., Bianchi, T., and Barni, M.

Abstract

Neural networks are a fundamental tool in data classification. A protocol whereby a user may ask a service provider to run a neural network on an input provided in encrypted format is proposed here, in such a way that the neural network owner does not get any knowledge about the processed data. At the same time, the knowledgeb embeddedwithin the network itself is protected.With respect to previousworks in this field, the interaction between the user and the neural network owner is kept to a minimum without resorting to general secure multi-party computation protocols.

12. Trellis-Coded Rational Dither Modulation for Digital Watermarking.

Author

Barni, Mauro, Cox, Ingemar, Kalker, Ton, Kim, Hyoung Joong, Abrardo, A., Barni, M., Pérez-González, F., and Mosquera, C.

Abstract

Rational Dither Modulation has been proposed as an effective QIM watermarking algorithm which is robust against value-metric scaling. Invariance is obtained by quantizing a rational function of the host features instead of the features themselves. In this paper we propose a vector extension of the basic RDM scheme. Specifically, a sequence of feature ratios is quantized vectorially with the aid of a properly designed dirty trellis code. A fast sub-optimum embedding algorithm is proposed ensuring fast watermark insertion and good distortion properties. Preliminary results show that a significant advantage is obtained with respect to conventional RDM. [ABSTRACT FROM AUTHOR]
