Big Data is a term that has jumped overnight from its roots. It can be described as an innovative technique and technology to save, distribute, manage, visualize and analyze larger-sized data with extreme velocity and methods to manage unstructured and structure incapable amount of data. Big data has high capacity to predict conclusion, with low cost consumption, increase efficiency and enhance decision-making in various fields like finance management, fraud control and to improve business transaction. In existing system the amount of customers, services and online transaction has grown rapidly, often suffer from scalability and inefficiency problems when processing or analyzing such large-scale data. Nowadays fraud transactions in real time are increasing, so identifying large-scale patterns across many transactions or detecting anomalous behavior from an individual user can change the fraudulent in online transaction. Thus banks are turning to analytics to predict and prevent fraud in real times. Fraud detection traditionally focused on the factors such as known bad IP addresses or unusual login times. In this project, proposed system deals with Credit / Debit card management to improve its scalability and efficiency in big data environment, it is implemented on (HDFS) Hadoop distributed file system, a widely-adopted distributed computing platform using the Map Reduce parallel processing paradigm that stores large files (typically in the range of gigabytes to terabytes) across multiple machines. On the other hand, nowadays fraudulent and web attacker are increased to steel the password. In order to overcome those, proposed system implements SyferLock concept to add more security to Credit card transaction. The changes include a stronger user authentication tool, SyferLock that will require associates to follow a few new steps when logging into the network remotely. SyferLock patented, random number generation authentication solutions provide next generation One-Time Passwords/PINs (OTPs) for secure access to computers, networks and the Internet. SyferLock has engineered an enhanced authentication methodology and system using device-less OTPs that provides users with a simple, more secure way to access information leveraging their existing passwords. It uses a one-time password that expired once used. This added security strengthens the ability to protect the applications and systems.
