| Security is
probably one of the most significant concerns for both the
shopper and the retailer during an online transaction. In
reality an online transaction is probably more secure than a
card transaction in a shop or conducted over the telephone or by
fax, as the information transmitted online is highly encrypted
using complicated logarithm combinations.
The WorldPay payment system uses a
combination of both established and innovative techniques to
ensure the security and integrity of all sensitive data.
Furthermore, our public web servers are certified by Thawte, a
public Certificate Authority, ensuring that both the shopper and
retailer can have confidence that nobody can impersonate
WorldPay to obtain confidential information.
Transaction Encryption
The transfer of the purchase
details from the retailers site to WorldPay are encapsulated
using our own encrypted and digitally-signed protocol. This uses
a combination of standard methods such as PGP, RSA and MD5 to
ensure that the information passed is secure and tamper-proof.
Data Storage
Data storage on WorldPay
systems, and the communication between WorldPay and the
worldwide banking networks, is regularly audited by the banking
authorities to ensure a secure transaction environment. We also
ensure that we stay up-to-date with the latest versions of any
third-party code we use, and continually review our own
proprietary code.
