3D Secure stands for 3 Domain Secure. There are 3 parties involved in the 3D Secure process which are:

•   The Vendor
•   The Acquiring Bank
•   Visa and MasterCard

3D Secure is a culmination of Verified by Visa (VbV) and MasterCard Secure Code (MSC). It is the latest fraud prevention initiative launched by card schemes as a more secure method for authenticating the shopper at the time of the transaction. Visa and MasterCard will take responsibility for your 3D Secure Authenticated transactions, taking the liability and reducing the risk of chargebacks. (Please double check with your merchant acquirer on any occasions you believe liability should have shifted).
