DESC:TECHNICAL FIELD
[001] The present disclosure relates to a method and system for data transmission, more particularly the disclosure relates to a secure remote for point-to-point file transfer from isolated devices using Internet of things.

BACKGROUND
[002] The internet of things (IoT) is a networking of physical devices (also referred to as "connected devices" and "smart devices"), such as vehicles, home appliances, machines, computers, and other network-connected items embedded with electronics, software, sensors, actuators, and enabling these objects to collect and exchange data. IoT enables objects to be remotely sensed and/or controlled over existing network infrastructure.
[003] The shopfloor environment has a lot of machines and systems that collect large amounts of product data. Many of these systems do not get regular software updates that can ensure that there are no live security threats. Such machines cannot be connected to a network as the system vulnerability can spread through the network.
[004] Hence, for security reasons, industrial devices in legacy systems are not allowed to directly accept connections from the internet, and typically only allow secure output connections from them. In this case, the industrial device itself is not connected to any internet-facing device, but rather to a local interior gateway or edge computing device. The gateway may again connect to another interior gateway at a higher system level and so on until the last highest level interior gateway then connects to the internet.
[005] Traditional remote access methods such as Virtual Private Networks (VPNs) and Remote Desktop Connections (RDCs) lack the flexibility and intelligence to meet today's needs of industrial organizations due to time-consuming and complex setup and security issues. Further, extracting data from such systems on a real-time basis is very difficult and usually data is extracted manually.
[006] Existing industrial Internet of Things creates a secured tunnel for data exchange between the PC and the IOT platform. Creating a tunnel requires a high compute and an operating system at the edge which adds to the level of complexity.
[007] Accordingly, there is a need to provide a system and method to extract important information and data points from computer systems that are isolated and cannot be connected to the network because of legacy and vulnerable software programs installed.

OBJECTS OF THE INVENTION
[008] An object of the present invention is to extract important information and data points from computer systems that are isolated and cannot be connected to the network.
[009] Another object of the present invention is to provide point-to-point file transfer from an isolated device using an IOT device.
[0010] An object of the invention is to provide a system for point-to-point file transfer from isolated devices using an IoT device, which enables seamless data extraction and transmission from legacy machines with out-of-support operating systems, thereby overcoming connectivity limitations.
[0011] Another object of the invention is to facilitate the conversion of new data from an internal database into a data string using a data conversion utility, which appends master information such as machine number and timestamp, enhancing data traceability and integrity.
[0012] Yet another object of the invention is to enable the transmission of the data string from the legacy machine to a gateway via a serial port, such as a USB port, ensuring compatibility with existing hardware interfaces.
[0013] A further object of the invention is to provide a gateway configured to receive the data string and create a payload for transmission to a cloud-based IoT platform, utilizing communication methods such as ethernet, wifi, or GSM, thereby ensuring flexible and reliable data transfer.
[0014] An additional object of the invention is to incorporate an isolation interface to facilitate automated data extraction from the legacy machine, thereby minimizing manual intervention and reducing the risk of data loss or corruption.
[0015] Another object of the invention is to enable the legacy machine to aggregate data locally for controlling certain machines, thereby enhancing operational efficiency and decision-making processes.
[0016] Yet another object of the invention is to ensure that the internal database is hosted locally on the legacy machine, providing a secure and efficient data storage solution that supports the system's overall functionality.
