Abstract

A network interface receives transaction information. A processor determines private information and public information from the received transaction information. The network interface communicates the private information to an obfuscation engine, and receives obfuscated private information. The processor then merges the obfuscated private information with the public information to create a temporary identifier, and then converts the temporary identifier into a transaction identifier. A printer then prints a portion of the public information and the transaction identifier on a transaction receipt.

First claim

What is claimed is:

1. A system, comprising:
a network interface operable to receive transaction information;
a processor communicatively coupled to the network interface and operable to determine private information and public information from the transaction information;
the network interface further operable to:
communicate the private information to a obfuscation engine; and
receive obfuscated private information from the obfuscation engine;

the processor further operable to:
merge the obfuscated private information with the public information to create a temporary identifier; and
convert the temporary identifier into a transaction identifier, wherein the transaction identifier comprises a hexadecimal representation of the temporary identifier;

a printer communicatively coupled to the network interface and processor and operable to print a portion of the public information and the transaction identifier on a transaction receipt; and
a scanner communicatively coupled to the network interface and the processor and operable to scan the transaction receipt;
wherein the processor further operable to:
automatically identify the transaction identifier on the transaction receipt;
convert the transaction identifier into the temporary identifier; and
parse the temporary identifier into the obfuscated private information and the public information; and

wherein the network interface further operable to:
communicate the obfuscated private information to the obfuscation engine;
receive the private information from the obfuscation engine;
communicate the temporary identifier to the obfuscation engine; and
receive an obfuscated temporary identifier from the obfuscation engine.

2. The system of claim 1 , wherein the processor is further operable to:
automatically identify public information on the transaction receipt;
compare the parsed public information from the temporary identifier with the identified public information on the transaction receipt; and
when the parsed public information does not match the identified public information, flag the transaction receipt.

3. The system of claim 1 , wherein:
the transaction information comprises an account number; and
the account number comprises personal information and public information.

4. The system of claim 1 , wherein the transaction identifier is a quick response (“QR”) code.

5. A method, comprising:
receiving, by a network interface, transaction information;
determining, by a processor, private information and public information from the transaction information;
communicating, by the network interface, the private information to an obfuscation engine;
receiving, by the network interface, obfuscated private information from the obfuscation engine;
merging, by the processor, the obfuscated private information with the public information to create a temporary identifier;
converting, by the processor, the temporary identifier into a transaction identifier, wherein the transaction identifier comprises a hexadecimal representation of the temporary identifier;
printing a portion of the public information and the transaction identifier on a transaction receipt;
scanning the transaction receipt;
automatically identifying, by the processor, the transaction identifier on the transaction receipt;
converting, by the processor, the transaction identifier into the temporary identifier;
parsing, by the processor, the temporary identifier into the obfuscated private information and the public information;
communicating, by the network interface, the obfuscated private information to the obfuscation engine;
receiving, by the network interface, the private information from the obfuscation engine;
communicating, by the network interface, the temporary identifier to the obfuscation engine; and
receiving, by the network interface, an obfuscated temporary identifier from the obfuscation engine.

6. The method of claim 5 , further comprising:
automatically identifying, by the processor, the public information on the transaction receipt;
comparing, by the processor, the parsed public information with the identified public information; and
when the parsed public information does not match the identified public information, flagging the transaction receipt.

7. The method of claim 5 , wherein:
the transaction information comprises an account number; and
the account number comprises personal information and public information.

8. The method of claim 5 , wherein the transaction identifier is a quick response (“QR”) code.

9. Non-transitory computer readable medium comprising logic, the logic, when executed by a processor, operable to:
receive transaction information;
determine private information and public information from the transaction information;
communicate the private information to an obfuscation engine;
receive obfuscated private information from the obfuscation engine;
merge the obfuscated private information with the public information to create a temporary identifier;
convert the temporary identifier into a transaction identifier, wherein the transaction identifier comprises a hexadecimal representation of the temporary identifier;
print a portion of the public information and the transaction identifier on a transaction receipt;
scan the transaction receipt;
automatically identify the transaction identifier on the transaction receipt;
convert the transaction identifier into the temporary identifier;
parse the temporary identifier into the obfuscated private information and the public information;
communicate the obfuscated private information to the obfuscation engine;
receive the private information from the obfuscation engine;
send the temporary identifier to the obfuscation engine; and
receive an obfuscated temporary identifier from the obfuscation engine.

10. The computer readable medium of claim 9 , wherein the logic is further operable to:
automatically identify the public information on the transaction receipt;
compare the parsed public information with the identified public information; and
when the parsed public information does not match the identified public information, flag the transaction receipt.

11. The computer readable medium of claim 9 , wherein:
the transaction information comprises an account number; and
the account number comprises personal information and public information.
