The USB-based security system that has been developed through this research does not contain users' fingerprint information on the server or enter controller. However, it incorporates the USB that the users carry. Thus, when the system becomes lost, only the registered user will be able to open the files that have been saved in the USB, because the registered fingerprint information only matches that of the user. Therefore, it is a safe and hack-free system. The security level has been upgraded and the system can be used for various purposes, such as commute management and access control. Moreover, the Zigbee module and the Zigbee AP have been added so that an integrated security system can be developed to document security or a location-based security service in order to build a stronger security system.

In the paper we proposed advanced methods of USB security software using file system recomposition and unassigned arbitary disk area. It provides data confidentiality of the USB storage device in the Windows OS using forced disk partition division by offering the real time data password in secure area. The confidentiality is also served by using user login verification and saving encoded the hash value at the unassigned arbiraty disk partition.

Nowadays is very common for homes or buildings in general to have some kind of automation system for the efficient use of energy and for common comfort matters like illumination and blinds & shutters controlling, among others. It can easily add to these systems different kind of sensors for different uses like: monitoring building structure health, monitoring elder people behavior, etc… In this work we have developed a system that access data from connected KNX sensor devices and sends it remotely to a MySQL server using IP packets.

This paper proposes a novel approach to prepare an Artificial Sensory Head which can recognize senses (speech, vision) and change its facial expression according to it. These are basic human expressions like happy, sad, angry, fear, surprise and disgust.The ASH receives input from user which may be in the form of speech or image. On receiving input from user of the system the type of emotion is detected. A bit pattern corresponding to each emotion is set. This generated bit is sent to the target application through usb port. The microcontroller is programmed with the logic to activate the driver at the end. In our methodology, in the end a face model is implemented as driver. This face model has some optical device which is placed at the positions where change would occur during change in facial expressions. These locations are identified from pre determined motion vector of still images and optical devices are placed accordingly. On detection of emotion, an impulse is sent to these optical devices and the ones placed at the points which changes during change in facial expression would glow denoting the direction and location of change in emotions. All throughout the process, we have an face model that can be activated by speech and image.

Portable SW는 사용자가 정품 보유 중인 제3자 응용 프로그램 라이선스를 자신만의 USB 메모리 등 저장매체에 담아서 제3자의 PC상에서 사용 가능 하도록 하는 소프트웨어 도구이다. Portable SW는 장소적 제약 없이 어느 곳에서든 자신의 환경에서 작업하던 소프트웨어를 지속적으로 사용하게 해 주는 편의성을 제공해 준다. 그러나 Portable SW는 정당한 권원을 가지는 사용자가 자신이 보유하고 있는 소프트웨어를 USB 메모리에 저장해서 제 3의 PC상에서 사용할 수 있도록 해 주는 소프트웨어 도구(tool)이며 이러한 도구의 사용이 SW저작권(프로그램저작권)을 침해하였는지가 문제되고 있다. 특히 스넵샵 과정과 함께 응용 프로그램의 역설치 과정인 팩(pack) 단계에서는 복제권의 침해 여부가 문제시 될 수 있다. 스넵샷 과정에서 사용자가 생성한 정보가 응용 프로그램과 동일한 형태의 복제물에 해당한다고 하더라도 이 정보는 당해 응용 프로그램의 사용에 대해 정당한 권원을 가진 사용자에 의해 자신의 PC에서 직접 수행한 것이기 때문에 ‘사적복제에 의한 사용’에 해당되어 복제권의 침해를 구성하기 어렵다고 본다. Portable SW를 이용한 응용 프로그램의 사용형태와 유사한 사적 복제의 대표적인 예로서, 개인적 사용을 목적으로 정당하게 보유하고 있는 아날로그 영상 데이터를 인코딩하여 동영상 플레이어(player)로 재생하거나 음악 CD에 담긴 음원을 MP3 플레이어에서 사용할 수 있도록 파일로 변환하는 행위 등이 있다. 이와 같이 사적 복제에 관해 현행 법률은 그 대상이 영상물, 음원, 소프트웨어 등이냐에 관계없이 정당하게 소유하고 있는 저작물을 개인이 비영리 목적으로 직접 복제하여 사용하는 것을 허용하고 있다. 따라서 정당한 권원을 가진 사용자가 portable SW를 이용하여 보유한 정품 SW를 USB 메모리에 저장하여 사용하는 행위는 사적복제에 의해 허락된다. 그러나 보유한 SW가 국내·외에 널리 판매되고 있는 것으로서 불법 복제된 것이라면 이는 portable SW 사용 이전에 이미 저작권자의 경제적 이익을 부당하게 해하는 경우로서 저작권 침해에 해당될 수 있다. 한편, Portable SW를 이용하여 팩(pack)된 응용 프로그램을 무력화하여 인터넷 망을 통하여 유포할 가능성도 검토해 볼 필요가 있다 .팩된 응용 프로그램을 공중이 개별적으로 선택한 시간과 장소에서 수신하거나 이용할 수 있도록 인터넷에 무단 제공할 경우에는 SW저작권자의 전송권을 침해하게 된다.

Potable software is easily installed on any portable storage gadget a user choose – whether it’s a thumb drive, a USB storage, or a pocket hard drive – portable software allows a user to enjoy the convenience and productivity of user's personal computer on any host PC. However, there is a copyright issue whether another copy on a portable device by using the portable software should be condemned under the Korean Computer Program Protection Act. This article addresses the technical concept of portable SW and examines copyright issues raised in three steps of using portable SW. Especially it applies the fair-use doctrine and the first-sale doctrine to the copyright issues, and insists that a duplication of packaged software a user owned during the packing process is belong to personal non-commercial copy and aims non-concurrent use of software, which is immune from copyright claims. Some of portable SW institute technological protection measures to protect copyrighted packaged software, and the process of making copy of software is very similar to the process of making MP3 and DVD file from analog sources. Yet, if a user copies packaged software for the purpose of distribution of them in many memory storages, it may infringe software owner's copyright.

Detection systems in a range of fields including medical science, food safety, and environmental monitoring use miniaturized polymerase chain reactions that have lab-on-a-chip technologies. The chip used for a micro PCR needs the correction factor of the chip temperature sensor for the exact measurement and control of temperature. The correction factor of the temperature sensor is obtained from the chip, generated as a quick response code, and attached to the chip. A universal serial bus camera connected to a PC reads the QR codes, and the data from the QR codes is used to correct the measured temperature. However, because several USB cameras cannot be operated on a single PC, users must bear the inconvenience of physically connecting USB cameras to PCs for use. In this thesis, we establish a system that automatically turns the USB cameras on and off by operating solid state relay modules and a micro controller unit used in micro PCSs. As a result, preparing micro PCRs for experiments has become more convenient and less time consuming.

A Transcranial Doppler ultrasound system measures blood flow velocity of brain vessels. It displays power spectrum density to the computer display and measures other important parameters. For this measurement, transmission speed between equipment and a computer plays an important role. In order to provide processing of high rate data communication, most Transcranial Doppler ultrasound systems use digital signal processor which performs the process in hardware and is connected by a universal serial bus controller to the processor. This research presents a new design of the Transcranial Doppler ultrasound system using CY7C68013 without digital signal processor and general programmable interface waveform of the CY7C68013 for the Transcranial Doppler ultrasound system. Also, this research describes control library for the personal computer and implemented software. According to the implemented software, the processing of Transcranial Doppler ultrasound system can be carried out.

We are accustomed to using various multimedia services through authorization as a legitimate user, by entering ID and password. However, while technology using ID and password in that case, is inexpensive for constructing system, and convenient for general public to use, user ID and password can be easily exposed to attackers by various attacking techniques, such as password guessing attack, reply attack, and others[1]. In order to resolve such problems, users can be authenticated by adding other authentication methods, such as security card, OTP, certification, finger print recognition, and others, to user authentication using ID and Password [2-5]. In this thesis, we suggest user authentication method that uses authentication data stored in USB memory after generating authentication data by combining USB memory info and user password in multimedia environment. In such system, even if attacker takes over user authentication data stored in USB memory, USB memory device info is still unknown, and thus, seized information cannot be used. In addition, it is convenient to use due to inexpensive construction cost and regular USB memory. Therefore, in the future, it is expected to provide easy construction and operation environment to the companies required to use ID and password based authentication.

In this paper, we propose link-adaptive cooperative communication in wireless USB networks. To select the optimal relay node, we propose the RNS (Relay Node Selection) algorithm considering channel condition. Also, the proposed protocol can be directly applied with small overhead to the current wireless USB standard system. Furthermore, each device independently performs RNS algorithm by using the proposed protocol.

In this paper, an IEEE 802.15.6 wireless body area networks (WBAN) medium access control protocol is developed to support a wireless USB (WUSB) application as a protocol adaptation layer (PAL). To successfully set up wireless communication links, the WUSB channel should be encapsulated privately within a WBAN superframe. However, in the current IEEE 802.15.6 WBAN standard there is no available periods allocated for other heterogeneous networks. In this paper, we propose a WBAN Beacon Structure (WBS) of IEEE 802.15.6 WBAN to set up WUSB channel efficiently. Simulation results show that the WBS integrates WUSB transactions and WBAN traffic efficiently in a hierarchical WUSB/WBAN medium access control (MAC) protocol.

Now a day’s Electronics plays a vital role in our daily life. It is a key in making this world a small and making everything happen at our finger tips, today’s most used and flexible is USB flash drives, which is used to store the data and data transfer between them related with computer, and we are not able to share files between two USB flash drives when user is away from computer. So to overcome this problem we are designing a complete blend of hardware and software With the help of this project we can not only transfer the data but also we can see the transfer of the particular file which we want to send by using LCD display. In our proposal we are transferring the data between two USB flash drives using two ways. One is Wireless Technology either Wi-Fi technology which we can send/receive File or Bluetooth Technology which we can send/receive data to USB flash drive with Bluetooth enabled devices like Mobiles, laptops etc.. Another is in-built USB slots to perform data transmission to other pen drives directly without the use of the computer system. The implementation of an operating system and a processor to the USB Flash drive are the main challenges in this proposed system.
