Echo Hiding
Homomorphic signal processing techniques are used to place information imperceivably into audio data streams by the introduction of synthetic resonances in the form of closely spaced echoes These echoes can be used to place digital identi cation tags directly into an audio signal with minimal objectionable degradation of the original signal
متن کاملAnomalies ∗
We present a holographic treatment of Chern-Simons (CS) gravity theories in odd dimensions. We construct the associated holographic stress tensor and calculate the Weyl anomalies of the dual CFT.
متن کاملMarket Anomalies on Return
There are various anomalies in the financial markets such as profitability, financial distress, lottery, volatility, and growth options, which origin and nature are unclear, ambiguous and apparently unrelated. In this study, we investigate the seemingly unrelated anomalies using the third and fourth moments of return’s distribution function and by isolating the expected skewness effect attribut...

ions that together allow these decisions to be isolated and hidden. Virtual topolo-gies, virtual channels, and lightweight processes provide mechanisms for isolating mapping,communication, and scheduling decisions, while port arrays allow these techniques to beapplied to program components that must execute on many processors.In addition to describing the abstractions, we have s...
متن کاملData Hiding System Based on New Multiple Echo Hiding Method
With the development of information society, audio steganalysis has attracted more attentions recently. Echo hiding method is one of the most challenging research fields. However, most of them can't solve the contradiction of capacity, robustness and imperceptibility, which restrict the development of the system seriously. Some of them have low capacity, and others have relatively high capacity...
