Abstract

Aspects of the current patent document include systems, methods, and computer program products for facilitating point of sale transactions and payment transactions.

Claims

1. A point-of-sale (POS) electronic system for conducting a commercial transaction, the POS electronic system comprising:

a data processing system comprising a terminal, a peripheral device that facilitates input of customer-related data indicating a payment request by a customer for the commercial transaction, and at least one data port that receives the customer-related data indicating the payment request from the peripheral device and that transmits at least a portion of the customer-related data to a central commerce system; and

central commerce system communicatively coupled to the data processing system that establishes an authenticated session with the data processing system and that receives the at least a portion of the customer-related data indicating a payment request and directly approves or declines the payment request by the customer without interfacing with an external financial institution,

wherein the central commerce system establishes the authenticated session with the data processing system by performing the steps comprising;

receiving a sequence of communications from the data processing system;

determining whether the sequence of communications satisfies a preset pattern,

responsive to the set of communications satisfying the preset pattern, establishing an authenticated session with the data processing system; and

responsive to the set of communications not satisfying the preset pattern, not responding to any of the set of communications, and wherein the preset pattern comprises;

receiving at a first port a first packet having a first size;

receiving, within a first time period after receiving the first packet, at a second port a second packet having a second size;

receiving, within a second time period after receiving the first packet, at a third port a third packet having a third size; and

receiving, within a third time period after receiving the first packet, at a fourth port a fourth packet having a fourth size.

2. The point-of-sale (POS) electronic system of claim 1 wherein the preset pattern further comprises one or more criteria comprising:

a particular packet from the series of packets was sent to a specific port;

a certain number of packets from the series of packets were sent to a specific port or specific ports;

a particular packet has a specific payload characteristic;

a certain number of packets from the series of packets have a specific payload characteristic or characteristics;

at least some of the packets from the series of packets follow an expected order;

at least some of the packets from the series of packets have an expected size or sizes;

at least some of the packets from the series of packets follow an expected timing;

a particular packet has a specific payload; and

a certain number of packets from the series of packets have a specific payload or specific payloads.

3. The point-of-sale (POS) electronic system of claim 1 wherein the preset pattern further comprises:

including a specific payload in at least one of the first, second, third, or fourth packets.

4. The point-of-sale (POS) electronic system of claim 1 wherein the sequence of communications comprises a set of packets and the step of determining whether the sequence of communications satisfies a preset pattern comprises:

verifying that each packet in the set of packets was received at a specific port and within a specific timing window according to the preset pattern; and

verifying that a payload of at least one of the packet contained expected information according to the preset pattern.

5. The point-of-sale (POS) electronic system of claim 4 wherein the step of verifying that a payload of at least one of the packet contained expected information according to the preset pattern comprises:

determining that a packet in the set of packets comprises an expected hash value in its payload.

6. The point-of-sale (POS) electronic system of claim 5 further comprising:

responsive to establishing a communication session with the data processing system, receiving from the data processing system a certificate; and

responsive to verifying the certificate, allowing the data processing system to interact with the central commerce system.

7. A computer-implemented method for facilitating secure network connecting, the method comprising:

receiving, at a first computing device, a series of packets of data originating from a second computing device;

determining whether the series of packets of data satisfy a specific set of criteria;

responsive to determining that the series of packets of data satisfy as specific set of criteria, attempting to establish a communication session with the second computing device;

responsive to determining that the series of packets of data do satisfy a specific set of criteria, not establishing a communication session with the second computing device;

responsive to establish a communication session with the second computing device, receiving from the second computing device a certificate; and

responsive to verifying the certificate, allowing the second computing device access to content on the first computing device.

8. The computer-implemented method of claim 7 further comprising:

not responding to any individual packet in the series of packets of data.

9. The computer-implemented method of claim 7 wherein the specific set of criteria comprises one or more criteria comprising:

a particular packet from the series of packets was sent to a specific port;

a certain number of packets from the series of packets were sent to a specific port or specific ports;

a particular packet has a specific payload characteristic;

a certain number of packets from the series of packets have a specific payload characteristic or characteristics;

at least some of the packets from the series of packets follow an expected order;

at least some of the packets from the series of packets have an expected size or sizes;

at least some of the packets from the series of packets follow an expected timing;

a particular packet has a specific payload; and

a certain number of packets from the series of packets have a specific payload or specific payloads.

10. The computer-implemented method of claim 9 wherein the specific set of criteria comprises:

receiving at a first port a first packet having a first size;

receiving, within a first time period after receiving the first packet, at a second port a second packet having a second size;

receiving, within a second time period after receiving the first packet, at a third port a third packet having a third size; and

receiving, within a third time period after receiving the first packet, at a fourth port a fourth packet having a fourth size.

11. The computer-implemented method of claim 10 wherein the specific set of criteria further comprises:

including a specific payload in at least one of the first, second, third, or fourth packets.

12. The computer-implemented method of claim 11 wherein the step of determining whether the series of packets of data satisfy a specific set of criteria comprises:

responsive to determining;

(1) that the first packet was received at the first port and was the first size;

(2) that the second packet was received within a first time period after receiving the first packet, was received at the second port, and was the second size;

(3) that the third packet was received within the second time period after receiving the first packet, was received at the third port, and was the third size; and

(4) that the fourth packet was received within the third time period after receiving the first packet, was received at the fourth port, and was the fourth size, verifying a payload of at least one of the first, second, third, and fourth packets.

13. The computer-implemented method of claim 12 wherein the step of verifying a payload of at least one of the first, second, third, and fourth packets comprises:

determining that at least one of the first, second, third, and fourth packets comprises an expected hash value in its payload.
