Systems and methods for securely transferring selective datasets between terminals

1. A method for securely transmitting data between two terminals connected via a computer network, the method comprising:

receiving, by a first communication device of the two terminals, an internet protocol (IP) packet via a first application programming interface (API) running on a first computer;

dividing, by a splitting unit in the first communication device, the IP packet into a command portion and a data portion, wherein the data portion comprises at least one of a customer name, customer address, fuel type, fuel price and fuel quantity;

encoding, by a data encoding unit in the first communication device, the data portion into a text delimited non-IP format; and

transmitting, by a transmitting unit in the first communication device, the encoded data portion and the command portion to a second communication device from the two terminals;

receiving, by the second communication device, a second IP packet via a second API running on the second computer;

dividing, by a splitting unit in the second communication device, the second IP packet into a command portion and a data portion;

determining, by one or more processors in the second communication device, when the command portion is whitelisted;

encoding, by a command encoding unit in the second communication device, the command portion into a non-IP format when the command portion is whitelisted; and

transmitting, by a transmitting unit in the second communication device, the encoded command portion and the data portion.

2. The method of claim 1 , further comprising:

receiving, by a second communication device, the encoded data portion and the command portion;

decoding, by a data decoding unit in the second communication device, the encoded data portion into IP format;

combining, by a constructor unit in the second communication device, the decoded data portion and the command portion to regenerate the IP packet; and

receiving, by a second API running on a second computer, the regenerated IP packet.

3. The method of claim 1 , further comprising:

receiving, by the first communication device, the encoded command portion and the data portion;

decoding, by a command decoding unit in the first communication device, the encoded command portion into IP format;

combining, by a constructor unit in the first communication device, the decoded command portion and the data portion to regenerate the second IP packet; and

receiving, by the first API running on the first computer, the regenerated second IP packet.

4. The method of claim 1 , wherein the command portion comprises at least one of a source address, destination address, and checksum, for data integrity.

5. The method of claim 1 , wherein encoding the command portion comprises 3-bit encoding of the command portion using out of bound digital command circuitry.

6. The method of claim 1 , wherein the encoding is selected from the group consisting of dual frequency tone encoding, 4-20 mA encoding, millivolt encoding, and light pulse repetition frequency encoding.

7. A system for securely transmitting data between two terminals connected via a computer network, the system comprising:

a first communication device of the two terminals connected to a first computer on the network, the first communication device comprising memory, a first splitting unit, a first data encoding and decoding unit, a first command encoding and decoding unit, a first constructor unit, and a first transceiver for sending and receiving IP packets over the network; and

a second communication device from the two terminals connected to a second computer on the network, the second communication device comprising a second splitting unit, a second data encoding and decoding unit, a second command encoding and decoding unit, a second constructor unit, and a second transceiver for sending and receiving IP packets over the network, wherein the first communication device is configured to:

receive an internet protocol (IP) packet via a first application programming interface (API) running on the first computer;

divide the IP packet into a command portion and a data portion using the first splitting unit, wherein the data portion comprises at least one of a customer name, customer address, fuel type, fuel price and fuel quantity;

encode the data portion into a text delimited non-IP format using the first data encoding unit; and

transmit the encoded data portion and the command portion using the first transceiver to the second communication device;

wherein the second communication device is further configured to:

receive a second IP packet via a second API running on the second computer;

divide the second IP packet into a command and a data portion using the second splitting unit;

determine, using one or more processors in the second communication device, when the command portion is whitelisted;

encode the command portion into a non-IP format using the second command encoding unit; and

transmit the encoded command portion and the data portion using the second transceiver.

8. The system of claim 7 , wherein the second communication device is configured to:

receive the encoded data portion and the command portion;

decode the encoded data portion into IP format using the second decoding unit;

combine the decoded data portion and the command portion to regenerate the IP packet using the second constructor unit; and

transmit the regenerated IP packet to a second API running on the second computer.

9. The system of claim 7 , wherein the first communication device is further configured to:

receive the encoded command portion and the data portion;

decode the encoded command portion into IP format using the first decoding unit;

combine the decoded command portion and the data portion to regenerate the second IP packet using the first constructor unit; and

transmit the regenerated second IP packet to the first API running on the first computer.

10. The system of claim 7 , wherein the command portion comprises at least one of a source address, destination address, and checksum, for data integrity.

11. The system of claim 7 , wherein encoding the command portion comprises 3-bit encoding of the command portion using out of bound digital command circuitry.

12. The system of claim 7 , wherein the encoding is selected from the group consisting of dual frequency tone encoding, 4-20 mA encoding, millivolt encoding, and light pulse repetition frequency encoding.

13. A non-transitory computer-readable medium including instructions stored thereon, which when executed by one or more processors operatively coupled to the computer-readable medium, cause the one or more processors to perform operations for securely transmitting data between two terminals connected via a computer network, wherein the operations comprise:

receiving an internet protocol (IP) packet via a first application programming interface (API) running on a first computer of the two terminals;

dividing the IP packet into a command portion and a data portion, wherein the data portion comprises at least one of a customer name, customer address, fuel type, fuel price and fuel quantity;

encoding the data portion into a text delimited non-IP format; and

transmitting the encoded data portion and the command portion to a second computer of the two terminals;

receiving, by the second computer, a second IP packet via a second API running on the second computer;

dividing, by the second computer, the second IP packet into a command portion and a data portion;

determining, by the second computer, when the command portion is whitelisted;

encoding, by the second computer, the command portion into a non-IP format when the command portion is whitelisted; and

transmitting, by the second computer, the encoded command portion and the data portion.

14. The medium of claim 13 , further causing the one or more processors to perform operations comprising:

receiving an encoded command portion and a data portion;

decoding the encoded command portion into IP format;
