Enhancing information security via the use of a dummy credit card number

A method, comprising:

• electronically associating, in response to a dummy credit card registration request from a user, a dummy credit card number with a first set of Global Positioning System (GPS) coordinates received from a mobile device of the user;
• generating, based on an input from the user, a first dummy credit card number as the dummy credit card number;
• receiving, from the mobile device, a transaction request to conduct a transaction involving the user, the transaction request containing a second dummy credit card number;
• retrieving, in response to the transaction request, a second set of GPS coordinates from the mobile device;
• determining whether the first set of GPS coordinates matches the second set of GPS coordinates and whether the second dummy credit card number matches the first dummy credit card number;
• and
• performing one of the following steps:
• approving the transaction request in response to a determination that the first set of GPS coordinates matches the second set of GPS coordinates and that the second dummy credit card number matches the first dummy credit card number;
• or
• denying the transaction request in response to a determination that the first set of GPS coordinates does not match the second set of GPS coordinates or that the second dummy credit card number does not match the first dummy credit card number;
• wherein at least one of the electronically associating, the generating, the receiving, the retrieving, the determining, the approving, or the denying is performed using one or more hardware processors.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• designating, in response to a dummy credit card registration request from a user, a registered location as a location at which dummy credit cards can be used and a registered device as a device on which dummy credit cards can be used, wherein the registered location includes a first set of Global Positioning System (GPS) coordinates;
• generating a first dummy credit card number as a part of the dummy credit card registration request;
• receiving, from a mobile device, a transaction request to conduct a transaction involving the user, the transaction request containing a second dummy credit card number;
• obtaining, in response to the transaction request, a second set of GPS coordinates of the mobile device and device identification information of the mobile device;
• determining, based on the obtaining, whether the mobile device is the registered device and is at the registered location, wherein the determining whether the mobile device is at the registered location comprises comparing the first set of GPS coordinates with the second set of GPS coordinates;
• determining, in response to the transaction request, whether the second dummy credit card number matches the first dummy credit card number;
• processing the transaction request at least in part by:
• approving the transaction request in response to a determination that the mobile device is the registered device and is at the registered location and that the second dummy credit card number matches the first dummy credit card number;
• or
• denying the transaction request in response to a determination that the mobile device is not the registered device, or the mobile device is not at the registered location, or the second dummy credit card number does not match the first dummy credit card number.
