Most state-of-the-art SPEs use punctuations to divide a stream into bounded substreams of messages, such as epochs and windows. The punctuation approach is powerful but has limitations: it does not support cyclic dataflows, is poorly scalable in some ...

Modern stream processing engines (SPEs) process large volumes of events propagated at high velocity through multiple queries. To improve performance, existing SPEs generally aim to minimize query output latency by minimizing, in turn, the propagation ...

This paper compares two objective audio quality assessment measures calculated for three watermark methods with its corresponding subjective quality. The aim was to see if these measures could be used to estimate the subjective audio quality with ...

Smart mobile devices such as smartphones and smart-pads based on Android or iOS are becoming more widely used. As smart mobile devices are increasingly used, their applications are also widely used for various purposes. Illegal uses of copyrighted ...

Digital watermarking for relational databases emerged as a candidate solution to provide copyright protection and tamper detection and to maintain the integrity of data. Sectors such as defense, finance, and human resources require reliable schemes, ...

We present a novel information hiding process that couples geometrical modeling with automated 3D fabrication for creating hidden-appearance reliefs. Our relief surface produces a first grayscale appearance visible by simple direct illumination and a ...

In this paper, a VWC-system is proposed. In the system, the embedded information can hold the secret for the encryption key. The system adopts the technique of frequency-domain watermarking and visual cryptography, respectively. Furthermore, the ...

In a buyer-seller watermarking protocol, buyers and sellers protect the ownerships or copyrights of their digital contents through the watermarks embedded in them. However, some known attacks and problems are still threatening the security of the ...

We used a new technique to analyse how students plagiarise programs in an introductory programming course. This involved placing a watermark on a student's program and monitoring programs for the watermark during assignment submission. We obtained and ...

We improve on the Boneh-Shaw Fingerprinting scheme in two ways: (i) We merge a Direct Sequence Spread Spectrum (DSSS) embedding layer with the first Boneh-Shaw layer (the so called " code"), effiectively increasing the protected object size by about ...

In this paper, we present a novel technique for embedding digital ``watermarks'' into digital audio signals. Watermarking is a technique used to label digital media by hiding copyright or other information into the underlying data. The watermark must be ...
