Abstract

Various embodiments of the present invention are directed to methods, systems and computer program products for conducting an online transaction on a website involving sensitive information. Such embodiments provide methods, systems and computer program products to: (a) register at least one entity with a gate keeper module, the registering comprising associating the entity with a subscription level; (b) associate a sub-string of a character string with a unique token so that a direct link does not exist between the unique token and the character string; and (c) during processing of the online transaction: (i) using the unique token for intermediate steps during the processing of the online transaction; and (ii) only accessing the character string in storage memory to complete the online transaction after receiving a request from at least one registered entity associated with a subscription level associated with a privilege to receive the requested sensitive information.

Claims

1. A method for using a unique token in an online transaction on a website to control access to sensitive information, the method comprising:

registering, by a server entity, at least one entity, wherein (a) registering comprises associating the at least one entity with a first subscription level of a plurality of subscription levels and storing access credential for the at least one entity and (b) each of the plurality of subscription levels is associated with a distinct set of privileges to control access to the sensitive information;

in response to receipt of the sensitive information from a merchant device, generating, by the server entity, a unique token for use in place of the sensitive information in online transactions, wherein the sensitive information comprises a character string stored as encrypted data;

saving, by the server entity, a record for the online transaction comprising information for the online transaction and the unique token;

using, by the server entity, the unique token for intermediate steps during processing of the online transaction; and

retrieving, by the server entity after receiving the access credentials for the at least one entity, the character string from storage memory using the unique token to complete the online transaction using the saved record and the sensitive information after transmission of a request for the sensitive information from at least one of the at least one registered entity associated with a subscription level associated with a privilege to receive the requested sensitive information.

2. The method of claim 1, wherein the online transaction is a purchase on the website and the character string is a credit card number.

3. The method of claim 2, wherein the sub-string comprises a last four digits of the credit card number.

4. The method of claim 1, wherein the character string is stored as encrypted data.

5. The method of claim 1, wherein the character string is stored as a record in a database within the storage memory.

6. The method of claim 1, further comprising:

verifying that a computer device or a user retrieving the sensitive information is authorized to access the character string.

7. The method of claim 1, further comprising:

receiving a request to display a sub-string of the character string, the request comprising the unique token; and

displaying the sub-string without revealing the sensitive information.

8. The method of claim 1, further comprising:

using the unique token to access and retrieve a sub-string of the character string without accessing the character string.

9. A data processing system for using a unique token in an online transaction on a website to control access to sensitive information, the data processing system comprising a processor and one or more storage devices embodying computer-readable program instructions that, when executed by the processor, cause the data processing system to:

register at least one entity, wherein (a) registering comprises associating the at least one entity with a first subscription level of a plurality of subscription levels and storing access credentials for the at least one entity and (b) each of the plurality of subscription levels is associated with distinct set of privileges to control access to the sensitive information;

in response to receipt of the sensitive information from a merchant device, generate a unique token for use in place of the sensitive information, wherein the sensitive information comprises a character string stored as encrypted data;

save a record for the online transaction comprising information for the online transaction and the unique token;

use the unique token for intermediate steps during processing of the online transaction; and

retrieve, after receiving the access credentials for the at least one entity, the character string from storage memory using the unique token to complete the online transaction using the saved record and the sensitive information after transmission of a request for the sensitive information from at least one of the at least one registered entity associated with a subscription level associated with a privilege to receive the requested sensitive information.

10. The data processing system of claim 9, wherein the online transaction is a purchase on the website and the character string is a credit card number.

11. The data processing system of claim 10, wherein the sub-string comprises a last four digits of the credit card number.

12. The data processing system of claim 9, wherein the character string is stored as encrypted data.

13. The data processing system of claim 9, wherein the character string is stored as a record in a database within the storage memory.

14. The data processing system of claim 9, wherein the computer-readable program instructions, when executed by the processor, further cause the data processing system to:

verify that a computer device or a user retrieving the sensitive information is authorized to access the character string.

15. The data processing system of claim 9, wherein the computer-readable program instructions, when executed by the processor, further cause the data processing system to:

receive a request to display the sub-string, the request comprising the unique token; and

display the sub-string without revealing the sensitive information.

16. The data processing system of claim 9, wherein the computer-readable program instructions, when executed by the processor, further cause the data processing system to:

use the unique token to access and retrieve a sub-string of the character string without accessing the character string.

17. A computer program product for using a unique token in an online transaction on a website to control access to sensitive information, the computer program product comprising a computer-readable storage embodying computer-readable program instructions that, when executed, cause a processor to:

register at least one entity, wherein (a) registering comprises associating the at least one entity with a first subscription level of a plurality of subscription levels and storing access credentials for the at least one entity and (b) each of the plurality of subscription levels is associated with a distinct set of privileges to control access to the sensitive information;
