Introduction to invoice hashing: securing VAT reporting with cryptography

Previously, we explained that real-time invoice reporting systems can tackle VAT fraud without collecting massive amounts of data. Companies will still need to register invoices, but instead of storing the data in “plain text” at a centralized location, always accessible to authorized personnel, VAT fraud can be detected even if the data is encrypted. An essential part of confidential real-time invoice reporting is that instead of storing invoice data itself, a unique fingerprint can be created of the invoice using so-called cryptographic hashing.

VAT Talks - Gerard Bottemanne

In this episode of VAT talks we speak with Gerard Bottemanne. Gerard has been conducting research into accounting software and related subjects for years. One of those subjects is e-invoicing, something that is very relevant in the realm of VAT as we briefly discussed in a previous blogpost. In this blogpost we discuss the latest development of e-invoicing in the Netherlands and the EU, the importance of harmonisation and the role of Peppol in this regard.

European Commission projects a 17% increase of the VAT gap in 2020

On September 10th the European Commission published its annual VAT gap report. The report shows that the European Union Member States lost a total of €140 billion in VAT in 2018. Even more worrisome is the forecast that those same Member States will lose a total of €164 billion in VAT over 2020 due to the COVID-19 pandemic. Luckily there is also positive news as Commissioner Gentiloni is planning to ‘step up the fight against VAT fraud’.

How to make deterministic PGP keys

In our last post, we discussed why we built a new PGP key generation. In today’s article, we’ll share a step-by-step guide on how to generate, use and store the PGP keys in a manner which is as secure and resilient as possible. This guide is inspired by the Glacier Protocol [1], which offers an extensive guideline on how to generate Bitcoin keys from your own source of entropy. The cryptocurrency community developed a suite of technologies and ideas to improve handling cryptographic keys.

State-level security with deterministic PGP keys

summitto released an open source software library and utility: https://github.com/summitto/pgp-packet-library https://github.com/summitto/pgp-key-generation These allow anyone to easily generate secure PGP keys with excellent support to backup your keys. In this article, we provide a brief but dense explanation of why we chose to build this. In the next post we will explain to you in depth how to use it. Pretty Good Privacy PGP stands for Pretty Good Privacy.
