Abstract:
Cryptography makes secure websites and electronic
safe transmission possible. For a web site to be secure all of the
data transmitted between the computers where the data is kept
and where it is received must be encrypted. This allows people
to make purchases for online shopping with their credit cards,
without worrying that any of their account information is being
compromised. The prevention of credit card fraud is an
important application for online shopping process. Therefore,
online shopping stores need to validate credit card with credit
card validation servers. Moreover, while transferring credit
card data over the communication channel, some threats may
also occur. Credit card validation servers provide secured web
services for the credit card fraud prevention. This system
presents how to send credit card number and password security
from online stores to credit card validation servers for validity
checks. Triple DES algorithm will be used for secure sending
over the communication channel. Triple DES provides efficient
and secured modification of DES algorithms and its symmetric
algorithm.
