Worker Checks private blockchain protecting your Police Check personal data

The foremost challenge in our increasingly online world is trust. Protection of sensitive personal information, in this case – protecting your police check data. In the contemporary environment, this can be extremely difficult and with considerable challenges.

We have written this short article to answer the common question on why we use private blockchain technology in our business. Our partners want zero compromise on factors such as authenticity, data validity and above all protection of personal information.

Private Blockchain technology is essential for addressing these factors – the most notable being the highest level of protection of sensitive personal information.

Private Blockchains offers supreme levels of privacy and is essential for Worker Checks to handle private and sensitive information. Unlike public blockchains, they are not accessible to everyone.

Protection of Sensitive Police Check Personal Information

Protecting your police check data, such as your photo, address, criminal record check is securely and stored on our private blockchain. This information is protected by a secure login accessible to only you.

Worker Check’s blockchain has no single database, so in the unlikely event a hacker gains access to one node, they cannot gain access to the other nodes to make sense of the stored data.

Your data is distributed across a network of computers, which means it is extremely unlikely to be hacked. The additional cryptography associated with our blockchain technology is best practice for information security.

Why we use a Private Blockchain for your Police Check?

After the emergence of blockchain technology, there have been many questions asked as to what the technology really offers. Is a private blockchain different to a database?

Data Handling – data entered can’t be altered

Data handling is by far one of the top differences between Private Blockchain Vs Database. In a private blockchain, users are only allowed to read and write and nothing else. So, once data is entered into the ledger, it cannot be altered in any way.

This is known as immutability, and is the essential feature of any blockchain technology.

In an orthodox database, users can write, read, delete, or update an entry after the initial data entry event. It follows CRUD protocol (create, read, update, delete). So, data can be manipulated, altered, or deleted if you have access to the database.

So, in instances where data integrity is paramount – the private blockchain is immensely superior to an orthodox database.

Importance of Data Protection in Police Checks

By using our own proprietary private blockchain – the only people with access to your data are you and Worker Checks. We do not utilise a public blockchain and as such no 3rd party has access to our system and your personal data.

Police Checks are essential in our society. Police check applications involve a lot of personal and sensitive data.

Private Blockchain is the best technology for Police Check Systems as it provides a high degree of security for sensitive personal information. Worker Checks’ Police Check System verifies the identity, and extracts personal information from the valid government systems before returning your police check result. This information is then stored on our blockchain.


In the above article, we have talked about important aspects of protecting sensitive personal information. We have also discussed why we use private blockchain technology for our business. From these discussions, it can be concluded that blockchain technology is the best solution for securing sensitive personal information.
