Abstract

A mechanism for flexibly securing data is discussed. A data entry device analyzes data from a user with respect to a security industry whitelist and an originator list and an analysis result controls a masking level of the data. The security industry whitelist references types of data that is not subject to industry-defined encryption standards. The originator list references data originators that produce data requiring non-standard handling. The data from the user is transmitted to and further examined for non-compliance with a pre-defined criteria at a computing device.

First claim

We claim:

1. A system for flexibly securing data, the system comprising:
a data entry device (DED) in communication with a computing device and configured to:
receive a security industry whitelist and an originator list, the security industry whitelist referencing types of data not subject to industry-defined security standards, the originator list containing card Issuer Identification Numbers (IINs) that use a greater number of digits than a Payment Card Industry (PCI) standard-defined number of digits and require non-standard handling to comply with a PCI security guideline;
acquire data from a user;
analyze the data from the user using at least one of the security industry whitelist and the originator list, a result of the analyzing controlling a masking level of the data; and
transmit the data with the controlled masking level to the computing device; and
the computing device configured to:
examine the data from the user for non-compliance with a pre-defined criteria; and
transmit the data to an external server for authorization after analysis.

2. The system of claim 1 , wherein the data from the user is analyzed at the DED using the security industry whitelist, and the DED is further configured to:
determine that the type of the user data is referenced by the security industry whitelist; and
generate, in response to the determining, a message containing the user data in clear form.

3. The system of claim 1 , wherein the data from the user is analyzed at the DED using the security industry whitelist, and the DED is further configured to:
determine that the type of data is not referenced by the security industry whitelist; and
analyze the data from the user using the originator list in response to the determination that the type of the user data is not referenced by the security industry whitelist.

4. The system of claim 3 , wherein the DED is further configured to:
determine that an originator of the user data is referenced by the originator list; and
generate, in response to determining that the originator of the user data is referenced by the originator list, a message containing the data from the user , the message including an account number from the data that is at least partially masked, a reference ID indicative of a card issuer of a card on which the data is encoded and an Issuer Identification Number (IIN) from the data that is at least partially masked.

5. The system of claim 3 , wherein the DED is further configured to:
determine that the originator of the user data is not present on the originator list; and
generate, in response to determining that the originator is not on the originator list, a message containing the data from the user, the message including a masked account number from the data that is at least partially masked and a completely unmasked IIN number.

6. The system of claim 1 , wherein prior to the DED receiving the signed shutdown request, the computing device is further configured to:
receive at the computing device a message including at least some of the data from the user;
inspect the received data for non-compliance with the pre-defined criteria; and
generate the signed alert indicating that the received data from the user is possibly non-compliant with the pre-defined criteria based on the inspection, the signed alert transmitted to the DED.

7. The system of claim 1 , wherein the DED:
receives a signed shutdown request for the DED that was generated in response to a signed alert: generated by the computing device, the signed alert indicating that the received data from the user is possibly non-compliant with a pre-defined criteria;
verifies the digital signature for the signed shutdown request; and disables the DED in response to verification of the signed shutdown request.

8. The system of claim 1 , wherein the DED is further configured to:
receive a maintenance file containing a signed security industry whitelist and a signed originator list;
validate the maintenance file based on signatures included in the maintenance file; and
replace an existing security industry whitelist and originator list on the DED with the security industry whitelist and the originator list included in the maintenance file.

9. A method for flexibly securing data, comprising:
receiving at a data entry device (DED) a security industry whitelist and an originator list, the security industry whitelist referencing types of data not subject to industry-defined security standards, the originator list containing card Issuer Identification Numbers (IINs) that use a greater number of digits than a Payment Card Industry (PCI) standard-defined number of digits and require non-standard handling to comply with a PCI security guideline;
acquiring data from a user via the DED, the DED in communication with a computing device;
analyzing the data from the user at the DED using at least one of the security industry whitelist and the originator list, a result of the analyzing controlling a masking level of the data;
transmitting the data with the controlled masking level to the computing device;
examining the data from the user for non-compliance with a pre-defined criteria at the computing device;
transmitting the data to an external server for authorization after the analyzing.

10. The method of claim 9 , wherein the data from the user is analyzed at the DED using the security industry whitelist and, further comprising:
determining that the type of data is referenced by the security industry whitelist; and
generating, in response to the determining, a message containing the user data in clear form.

11. The method of claim 9 , wherein the data from the user is analyzed at the DED using the security industry whitelist and further comprising:
determining that the type of the data is not referenced by the security industry whitelist; and
analyzing the data from the user at the DED using the originator list in response to the determination that the type of the user data is not referenced by the security industry whitelist.

12. The method of claim 11 , further comprising:
determining that the originator of the data is referenced by the originator list; and
generating, in response to determining that the originator of the user data is referenced by the originator list, a message containing the data from the user , the message including an account number from the data that is at least partially masked, a reference ID indicative of an issuer of a card on which the data is encoded and an Issuer Identification Number (TIN) number from the data that is at least partially masked.

13. The method of claim 11 , further comprising:
determining that the originator of the user data is not referenced by the originator list; and
generating, in response to determining that the originator of the user data is not referenced by the originator list, a message containing the data from the user , the message including an account number from the data that is at least partially masked and a completely unmasked IIN number.

14. The method of claim 9 , wherein prior to the DED receiving the signed shutdown request, the method further comprises:
receiving at the computing device a message including at least some of the data from the user;
inspecting the received data for non-compliance with the pre-defined criteria; and
generating, at the computing device, based on the inspecting, the signed alert indicating that the received data from the user is possibly non-compliant with the pre-defined criteria, the signed alert transmitted to the DED.

15. The method of claim 11 , wherein the DED:
