Abstract

An apparatus for smart integrated cyclic data transport is provided. The apparatus may preserve the consistency and integrity of a file during the transfer of the file from a source system to a target system. The apparatus includes an orchestration subsystem. The orchestration subsystem includes an analyzer/generator module. The analyzer/generator module executes an algorithm on the file at the source location. An output is generated from the executed algorithm. The apparatus includes a consistency module. The consistency module pre-checks the output at the source location for pretransfer validation and creates a copy of the output. The copy may preserve the consistency and the integrity of the file. The apparatus includes a data transfer subsystem which transfers the file and the output from the source system to the target system. The apparatus may also include a validation subsystem for validating the integrity and consistency of the file.

Claims

1. An apparatus for smart integrated cyclic data transport, the apparatus for preserving the consistency and integrity of a file during the transfer of the file from a source system to a target system, the apparatus comprising:

an orchestration subsystem, the orchestration subsystem comprising;

an analyzer/generator module, the analyzer/generator module being configured to;

execute an algorithm on the file at the source location; and

generate an output from the executed algorithm;

a consistency module, the consistency module being configured to;

pre-check the output at the source location for pretransfer validation; and

create a copy of the output, the copy for preserving the consistency and the integrity of the file;

a data transfer subsystem configured to transfer the file and the output from the source system to the target system;

a validation subsystem for validating the integrity and consistency of the file at the source system, the validation subsystem configured to;

re-execute the algorithm on the transferred file;

generate a second output from the re-executing;

compare the transferred copy of the output and the generated second output in order to validate the integrity and consistency of the transferred file;

determine a correspondence metric between the transferred copy of the output and the generated second output based on the comparison;

when the correspondence metric is greater than a predetermined threshold level of correspondence, discard the transferred copy of the output and flag the file as verified;

when the correspondence metric is less than the predetermined threshold level of correspondence, transmit a message to a scheduling subsystem, said message regarding the lack of file integrity and consistency;

the scheduling subsystem configured to reschedule the transfer of the file from the source location to the target location in the event that the correspondence metric is less than the predetermined threshold level of correspondence.

2. The apparatus of claim 1, wherein the algorithm executed by the analyzer/generator module is a checksum algorithm performed on the contents of the file.

3. The apparatus of claim 1, further comprising a tagger module within the orchestration subsystem, wherein, prior to the transfer of the file and the output from the source system to the target system by the data transfer subsystem, the tagger module is configured to:

inject one or more identifiers into one or more binary locations within the file; and

recording the identifiers and their respective binary locations in the output.

4. The apparatus of claim 3, wherein, upon completion of the transfer of the output and the identifiers and their respective binary locations from the source system to the target system, the validation engine is configured to:

examine the transferred file for identifiers and their respective binary locations;

retrieve, from the transferred file, the examined identifiers and their respective binary locations; and

compare the retrieved identifiers and their respective binary locations with the identifiers and their respective binary locations previously combined with the output;

use the comparison of the retrieved identifiers and their respective binary locations with the identifiers and their respective binary locations recorded in the output to determine, at least in part, the correspondence metric.

5. The apparatus of claim 3, wherein, prior to the file transfer and upon completion of the tagger engine injecting the identifiers into the one or more respective binary locations within the file, an auditor engine verifies that the tagger engine has injected the identifiers into the binary locations recorded in the output.

6. The apparatus of claim 3, wherein, when the validation engine successfully verifies that the correspondence metric is greater than the predetermined threshold level of correspondence, the validation engine removes the identifiers from within the file prior to flagging the file as verified.

7. The apparatus of claim 3, wherein the output includes a touch sensor, said touch sensor being configured to transmit an alert to one or more stakeholders when a read and/or write function is attempted to be executed on the output, said read and/or write attempt occurring prior to receipt of the file at the target location.
