Data Encryption based upon Time Reversal Transformations

A New Fast Data Encryption Algorithm (FDE)

Mining Time Series Data Based upon Cloud Model

In recent years many attempts have been made to index, cluster, classify and mine prediction rules from increasing massive sources of spatial time-series data. In this paper, a novel approach of mining time-series data is proposed based on cloud model, which described by numerical characteristics. Firstly, the cloud model theory is introduced into the time series data mining. Time-series data c...

A New Fast Data Encryption Algorithm (FDE)

Speech encryption using circulant transformations

A new analog encryption technique using unitary circulant transformations of the sampled analog signal is proposed. This technique is less vulnerable to attack than other known schemes based on transposition(scramhling) of the signal components in time or frequency domain. The new technique introduces primarily a phase distortion. A new distonion measure capable of quantifying phase distortion ...

Low-bitrate video coding based upon geometric transformations

| Low-bitrate video coding receives much attention lately. Applications such as video-phone or real-time video transmissions over ATM networks or multi media have increased the interest to this challenging eld. This paper describes low-bitrate video compression based upon the characterization of the new frame as a set of geometric transformations of objects of the previous frame. Objects with m...
