Power Spectrum Condition for Energy-Efficient Watermarking
A simple but powerful theoretical model for watermarking and attacks is presented. The attack consists of Wiener estimation of the watermark, followed by weighted feedback of the estimate to reduce the detector's correlation value. The Wiener attack is provably optimal, and it leads to the notion of energy-e cient watermarking, the generation of watermarks that resist Wiener estimation. It also...
متن کاملCondition for Energy Efficient Watermarking with Random Vector Model without WSS Assumption
Energy efficient watermarking preserves the watermark energy after linear attack as much as possible. We consider in this letter non-stationary signal models and derive conditions for energy efficient watermarking under random vector model without WSS assumption. We find that the covariance matrix of the energy efficient watermark should be proportional to host covariance matrix to best resist ...
متن کاملPower Spectrum Compliant QIM Watermarking for Autoregressive Host Signals
The autoregressive (AR) model is widely used in modeling image, speech and EEG signals. Using this model as the model for the host signal, we have devised a watermarking algorithm which is compliant with the power spectrum condition. This is achieved by embedding the quantization watermark in the residual signal of the AR model, both for dither modulation (DM) watermarking and spread-transform ...
متن کاملPower Measurement Methods for Energy Efficient Applications
Energy consumption constraints on computing systems are more important than ever. Maintenance costs for high performance systems are limiting the applicability of processing devices with large dissipation power. New solutions are needed to increase both the computation capability and the power efficiency. Moreover, energy efficient applications should balance performance vs. consumption. Theref...
متن کاملMaking power plants energy efficient
Energy efficiency is ABB's business. So too is raising productivity for industry and increasing power plant output, as well as ensuring that facilities and processes operate reliably and the power grids they are connected to are stable. These four themes – energy efficiency, productivity, reliability and stability – are intimately connected. When ABB improves the energy efficiency of a power pl...
