Transaction Authentication Using HMAC-Based One-Time Password and QR Code

Conducting financial transactions over the Internet has been widely adopted due to the convenience and usability. However, conducting financial transactions via the Internet may be subjected to many types of attacks including password attacks, malware, phishing, and other unauthorized activities. Many banks have enhanced their security by using One-Time Password (OTP) as another authentication method in addition to traditional username and password. The OTP may be sent to the mobile phone number of the account owner via SMS. Even with the enhanced security measure, internet banking is still vulnerable to different types of attacks such as online phishing. We propose, design, and implement a transaction authentication scheme using HMAC-based mobile OTP and QR Code. Our scheme is resilient to known attacks including, but not limited to, eavesdropping, replay, message modification, and phishing.

Design of a new smallest wireless fingerprint in this research is small and easy to use. It has a LCD screen for show the result of identifying after users scan they fingerprint on it. This system is applying to use in class attendance. When student come in a class he or she scan his fingerprint on our device for checking and authentications. After device receive data from his fingerprint then device send this data to server using wireless network. When server get the data by device from network already, it will send this data to fingerprint authentications program for loading and checking data of fingerprint in database. If his fingerprint data is match one of data in database the server will be sent the name and information of matching fingerprint data back to LCD screen of device and show valid text on the screen and update the status of fingerprint owner to attendance system. If his fingerprint not math in all of data in database, it invalid. This research help an instructor for reduce time for checking student attendance; solve the problem about some student absent but his or her friend fake attendance for him. And in the future this device will be replacing the student ID card
