Có nên mua File Validator không?

This allows any user to timestamp important digital documents and files so that these can be verified for authenticity in the future. You'd like to timestamp an idea so you can prove you had it at a particular time? You'd like to timestamp an image you took to certify you are the owner? Do you want to timestamp a document you've written for a customer so they can always check if nobody else meddled with it? FileValidator enables you to do all of the above, and much more.
