This is a commandline program written in C++. This program imports data from CSV file to mysql database. Then uses two simple rules to detect fradulent transactions.
If a transaction by certain user is more than 2 standard deviation of it's transactions then it is flagged as fradulent. Such information is printed in screen and saved in file1.txt. Following is an example of such transactions.
Name Account Number Transaction Number Merchant Transaction Amount
Michael Smith 11111 15 KROGER 2300.00
Kolmetz Willard 14281 14 VZWRLSS*APOCC 351.05
Albares Cammy 14829 3 STADIUM 348.40
Albares Cammy 14829 4 POSTO 264.19
Rule 2 marks the transactions happened in a state other than where the person registered its account. Results are written in file2.txt and also printed on screen.
The rules have been implemented using SQL queries which can be found in rule*.txt file.
A additional dump file of the database is added com_db_dump.sql file.
This program is written and built in Ubuntu linux. FindMySQL script has been used to easily find out sql path by CMake. Reference: https://gitlab.kitware.com/cmake/community/-/wikis/contrib/modules/FindMySQL Install mysqlclient library using the command in debian linux sudo apt install libmysqlclient-dev
I have put the library headers in the misc folder in case someone is interested to look into it.
This headers usually found in /usr/include/mysql after installing the libarary.
The library has been linked using CMake command target_link_libraries(fraud_detector
For windows similar methods can be used. But I have not tested on widows
g++ myprog.cpp
-I"C:\Program Files (x86)\MySQL\MySQL Connector C 6.1\include"
-L"C:\Program Files\MySQL\MySQL Connector C 6.1\lib" -lmysql
It is CMake project. To make create directory to store the build files. FradudDetection$ mkdir build FradudDetection$cd build build$ cmake .. build$ make FradudDetection$ ./build/fraud_detector
