VeriDoc Global

Certificate verification solutions by implementing blockchain technology and public key cryptography.

Why Phonevacc?

The immutability of blockchain makes it almost impossible to counterfeit data and change information in the certificate once it is updated in the blockchain. So, whenever verifying a certificate, the government can rest assured that all the information is trusted and verified.

Why Phonevacc?

Phonevacc is a reputable name for offering Certificate verification solutions by implementing blockchain technology and public-key cryptography. Partnering with VeriDoc Global, we have been serving the industry for the last six years.

We have partnered with VeriDoc Global, a reputable organisation offering a trusted solution towards an honest and transparent future. Together, we are on a mission to eliminate vaccine certificate forgeries and counterfeits.

How does it work?

When the governments across the world sign up with us, they can create and verify a certificate with just a scan. By scanning the QR Code placed on a card, they will directly be redirected to a secure page showing all the information about the patient, including their name, age, sex, nationality, district, sub-county, phone number and more.


They will also see the record of treatment that shows if the person is vaccinated with the first dose or second dose, what vaccination they have taken, hospital name, doctor’s name, nurse’s name and the time of the vaccination.


The government or organisation will get to know a brief about the doctor, their email id, phone number, specialty and address and verify them.

Why VeriDoc Global?

VeriDoc Global has patented technology like nobody else. Their patents are granted in over 100 countries, and are bringing real document transparency to everyone. VeriDoc Global’s unique approach to document transparency and document security is a game changer.  We can now trust documents using this technology!!!!

VeriDoc Global uses unique hash values to verify whether a document is true and correct. The original document is processed using VeriDoc Global’s APIs, and a unique hash value, showing the original document was produced by the document owner. The unique hash value is stored on the VeriDoc Ledger and can NEVER be changed.  If the document is modified in any way, the unique hash value will also change significantly and the verification will fail.

After the covid pandemic everyone knows about QR codes. QR codes are a great vehicle for verifying a document using VeriDoc Global Technology, therefore anyone can easily see if a document is fraudulent or genuine by using their mobile phone and scanning the QR code on the document.

Why VeriDoc Ledger?

VeriDoc Ledger technology increases security , traceability , transparency and trust.

VeriDoc Ledger is a fork of the Ethereum blockchain, combining the transparency and trust of public blockchains with the security and immutability of private blockchains.

But why is this blockchain used for Phonevacc?


Data is sensitive and crucial, and VeriDoc Ledger can significantly change how your critical information is viewed.  By creating a record that can’t be altered and is encrypted, VeriDoc Ledger prevents all fraud and unauthorized activity in your documents. Information is stored across a network of computers rather than a single server, making it impossible for hackers to access the data.


VeriDoc Ledger has no one, central point of attack.  The fact that VeriDoc Ledger is a decentralised way of storing and accessing data makes the whole system incredibly secure – because, unlike a centralised databases, there’s no one single point of entry for hackers. This makes it particularly useful for recording data in a secure manner that you can trust.


Because VeriDoc Ledger is decentralised and replicated in its entirety in multiple places, there’s no need for a central administrator and all the costs and infrastructure that comes with it. This allows users of the technology to achieve their objectives in a more efficient manner therefore saving budget along the way.

VeriDoc Ledger creates an audit trail, that documents the recording, of all events in any document, until the document is completed.  In society today we are concerned about counterfeiting and fraud — this audit trial provides the proof we can trust. With VeriDoc Ledger, it is possible to share the trusted data directly with all users, so the journey of the document can be shown.  You get a history of activity, not just a snapshot in time.  When you look at a regular database, you’re getting a snapshot of data that’s up to date in that moment in time that is more than likely changeable. VeriDoc Ledger also maintains a record of all the information that exists, but it is immutable. It’s a database with history, you can trust.

VeriDoc Ledger uses technology that records data ( unique hash values ) identically in multiple locations - this is a decentralised network. When any VeriDoc Ledger user can access the ledger at any time, and see the same information as any other user at the same time - this creates an environment of full transparency to all VeriDoc Ledger users. All records are immutability recorded, and are time and date stamped. This allows all users to view the entire history of records and eliminates any opportunity for fraud.
