Abstract: People use cryptography to send secret messages to one another without a third party overseeing the message. Steganography is a type of cryptography in which the secret message is hidden in another message. In this paper, a method of hiding the speech signal inside a music file using LSB coding is proposed. The speech signal can be hidden inside music file by replacing the LSBs of the samples of music file by speech signal bits. At the receiver’s end, speech signal can be heard only when a pre-d

Abstract: Very often computation of multiple group -bys are done by OLAP applications. Many of the OLAP applications use cube operator. The cube operator requires computing group-bys on all possible combinations of list of attributes. If multiple copies of the same data are stored at different data bases then the OLAP applications evaluate same data cubes may number of times. This increases the cost of evaluation and performance time. Here we present a CROME based method of computing the data cubes.
