Operating system data file protection through authentication is very important. A file can be any important document which may contain data or information that may be very valuable for the company or the owner of the file. If proper authentication is not carried out then the company can incur loss of data, expose to viruses and trojan attacks and can face a lot of issues. Authentication also increases the value of the information saved in the files because it does not appear fake. By giving the authentication to the people, you can ensure that no unauthorized person will access the file or imitate it. Just take the example of art work of a person saved in a file. Therefore, identification of the person is very necessary before sharing any file with any other person.
