Method and system for ensuring dual bar code authentication of documents

A system comprising:

• a memory storing instructions;
• one or more Input/Output (I/O) interfaces;
• and
• one or more hardware processors coupled to the memory via the one or more I/O interfaces, wherein the one or more hardware processors are configured by the instructions to:
• receive a metadata corresponding to at least one scanned answer sheet from a user to create an entity for the at least one answer sheet, wherein the at least one answer sheet comprises two or more sheets;
• fetch a plurality of parameters of the at least one scanned answer sheet, wherein the plurality of parameters includes Dots per Inch (DPI) for horizontal and vertical pixel calculation, number of sheets in the at least one answer sheet, sequencing of the sheets, a file size, a file length for a mp3 format and folded sheets;
• scan a primary bar code on a front sheet of the at least one answer sheet to extract the metadata of the primary bar code and one or more details of the at least one answer sheet;
• compare the fetched plurality of parameters with the extracted metadata of the primary bar code of the at least one answer sheet to get a correct answer sheet stored in a predefined folder, wherein the predefined folder has a predefined folder code;
• identify a position of a secondary bar code using an adaptive machine learning, wherein the secondary bar code is pasted on a random sheet other than the front sheet of the at least one answer sheet;
• scan the identified secondary bar code on the random sheet of the at least one answer sheet to extract metadata of the secondary bar code and one or more details of the student metadata;
• and
• compare the primary bar code with the received metadata corresponding to the at least one scanned answer sheet and the secondary bar code to authenticate the at least one answer sheet, wherein both the primary bar code and secondary bar code is having same the predefined folder code.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• receiving, via an input/output interface, a metadata corresponding to at least one scanned answer sheet from a user to create an entity for the at least one answer sheet, wherein the at least one answer sheet comprises two or more sheets;
• fetching a plurality of parameters of the at least one scanned answer sheet, wherein the plurality of parameters includes Dots per Inch (DPI) for horizontal and vertical pixel calculation, number of sheets in the at least one answer sheet, sequencing of the sheets, a file size, a file length for a mp3 format and folded sheets;
• scanning a primary bar code on a front sheet of the at least one answer sheet to extract the metadata of the primary bar code and one or more details of the at least one answer sheet;
• comparing the fetched plurality of parameters with the extracted metadata of the primary bar code of the at least one answer sheet to get a correct answer sheet stored in a predefined folder, wherein the predefined folder has a predefined folder code;
• identifying a position of a secondary bar code using an adaptive machine learning, wherein the secondary bar code is pasted on a random sheet other than the front sheet of the at least one answer sheet;
• scanning the identified secondary bar code on the random sheet of the at least one answer sheet to extract metadata of the secondary bar code and one or more details of the student metadata;
• and
• comparing the primary bar code with the received metadata corresponding to the at least one scanned answer sheet and the secondary bar code to authenticate the at least one answer sheet, wherein both the primary bar code and secondary bar code is having same the predefined folder code.
