AN VIRTUAL KEUBOARD BASED AUTOMATIC TELLERT MACHINE FOR SECURITY IMPROVEMENT



project center in Tirunelveli 


An Automatic Teller Machine is a globally useful technology for money transactions like withdrawal, deposit and balance enquiry. The magnetic tape reader on an ATM is useful to recognize the customer’s profile by reading the magnetic codes on his/her debit card. After correctly giving the customer’s secreting PIN code, the account can be accessible now. In computer security, shoulder surfing refers to using direct observation techniques, such as looking over someone's shoulder, to get information. It is commonly used to steal PIN. This project introduces a novel technique for ATM debit card PIN security by incorporating an embedded system based Virtual Keyboard technique. The main idea behind this concept is create the virtual keyboard per single PIN digit. This keyboard is randomly generated by Microcontroller and it is producing different set of key arrangements during each PIN digit in order to avoid the shoulder surfing issue. The great advantage of the project is the user’s PIN cannot be steal by an anonyms due to the altering key per a single PIN digit. This project leads to a securable ATM transaction by strengthening the confidentiality of the PIN.

Security Solution for Internet Of Things(IOT) EXISTING SYSTEM FOR WOMEN SECURITY Having this concern in mind many developers have come up with creative applications. Some of such applications are: Codes like *91# is used to provide emergency services, which will alert police control. Free mobile application 'Help me on mobile' to ensure safety of women was launched to assist those who need emergency .These applications need a single click to do this task. But when a girl is in trouble, there can be times that the girl is not capable of taking the phone and pressing button. A.SHE (Society Harnessing Equipment): It is a garment embedded with an electronic device. This garment has an electric circuit that can generate 3800kV which can help the victim to escape. In case of multiple attacks it can send around 80 electric shocks [3]. B.ILA security: The co-founders of this system, have designed three personal alarms that can shock and disorient potential attacke

Gram Sandesh Transmission-A Web Based Information System for Farmers Agriculture is the fortitude for our country India. A large population of the country depends on farming related activities for their sustenance. However, it is perceived that there is lack of a handy agronomical information system for the end users. Information and data is available but does not reach the end-user on time [1]. Safekeeping this fact into consideration; Gram Sandesh Transmission has been developed so as to facilitate the flow of useful information required for farming [2]. In last few decades the trade of farming has changed rapidly. Apart from the traditional problems in farming, farmers are now facing competition from global market. They strictly need to adhere quality standards set by World Health Organization to trade in international market. An era has arrived where key to success is accurate, timely information and accurate judgment placed upon it [2], [3]. Present generation predominan

ANDROID APPLICATION CONTROLLED REMOTE ROBOT OPERATION

project center in Tirunelveli  The project is designed to control a robotic vehicle using an android application. Bluetooth device is interfaced to the control unit on the robot for sensing the signals transmitted by the android application. This data is conveyed to the control unit which moves the robot as desired. An 8051 series microcontroller is used in this project as control device. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. Transmitting end uses an android application device remote through which commands are transmitted. At the receiver end, these commands are used for controlling the robot in all directions such as forward, backward and left or right etc. At the receiving end the movement is achieved by two motors that are interfaced to the microcontroller. Serial communication data sent from the android application is received by a Bluetooth receiver interfaced to
