Bluetooth is a low cost, short-range radio technology, originally developed as a cable replacement to connect devices such as mobile handsets, headsets and portable computers. This technology has standardized wireless communications between electronic devices. It has created the notion of a Personal Area Network (PAN) approved by IEEE as 802.15.1 standard, a kind of close range wireless network that looks set to revolutionize the way people interact with the information technology landscape around them.
Sun Microsystems developed Java2 Micro Edition (J2ME) for compatibility with mobile devices, which includes class definitions to make it possible for the programmers to design software according to the necessity, which is compatible with Bluetooth device. Connected Limited Device Configuration (CLDC) devices have slow processors and limited memory, operate on batteries, and have only intermittent network connections. To support CLDC devices J2ME also includes Mobile Information Device Profile (MIDP) provides the java runtime environment. The paper presents implementation of Bluetooth file transfer profile using java. The implementation is done using J2SE and use Object Exchange (OBEX) protocol as well as Radio Frequency Communication (RFCOMM) protocol.

Objectives: Present work deals with FPGA based implementation of either watermarking or cryptography alone. Objective is to improve the security using less number of slices with optimum speed. Methods/Statistical Analysis: Digital data is easy to process but it allows illegal users to access the data. For protecting data from illegal use, Digital Rights Management can be used. In this paper, hardware implementation of combined watermarking and cryptography algorithm based watermarking is discussed. With this approach, improved security can be achieved due to use of encryption algorithm. Complete system is designed using Verilog and simulated using Questasim and MATLAB Simulink model. Findings: The highest performance of FPGA based watermarking algorithm alone achieved is 4708 slices at 344.34 MHz. Our combined watermarking and cryptography algorithm utilizes only 2117 at maximum operating frequency of 228.064 MHz. Due to this improved speed and optimized area, our design is economical for real time image processing applications. At the same time, due to use of AES algorithm it is proved that improved security can be achieved.Keywords
