V-ID’s 3 methods for validation

V-ID is a service that detects any unlawful manipulation of any digital file. In order to make files verifiable, they must be validated. V-ID’s validation process involves extracting the fingerprints of files and saving them in the blockchain. If a file is changed with just one byte, pixel, character or anything else, the fingerprint is changed and V-ID will detect it 100%.

It is crucial to have a secure validation method, because the key to confirm the authenticity of a file is to know the source.

V-ID offers 3 methods for validation:

Validation Service

V-ID staff members will do the actual validation for you on-site. If the client wishes, a V-ID-trained notary will be present as well to confirm ID’s and oversee the validation process.


This method allows an employee of the issuing organization to validate files at any time. First, an employee of the publishing organization is appointed to become a Validator. This person’s identity is established on site by a V-ID agent and V-ID-appointed notary. After V-ID has created the Validator’s profile on the platform, he or she is able to log in at a Validation Terminal. The Validation Terminal has a user friendly interface, where files that need to be validated can simply be submitted by dragging and dropping.

Bridge Validation

This validation method is a server-to-server process. The V-ID API extracts the fingerprint of a file from the code that the company software uses to create that file. This means that, for example, in the case of a typical dynamically generated PDF file, the V-ID API does not need to handle the file itself to still be able to validate the file. This validation process is completely non-intrusive to the normal workflow at the company.


After a file is validated, one part of the V-ID security process is done. The other side of V-ID’s mission to secure our digital world, is Verification. This is where files can be checked for authenticity.

This live demo shows how fast and easy V-ID file verification works. As you can see, a validated file can be verified in 5 seconds by any recipient with internet access.
