4 min readMay 16, 2023

The digital age has brought immense convenience and efficiency to our daily lives, but it has also introduced new challenges when it comes to verifying the authenticity of documents. PDFs are a widely used format for sharing important information, but the ease with which they can be altered leaves room for fraud and misrepresentation. This has led to a demand for a more secure way of sending and receiving PDF documents. Enter Lissi and its ID-Wallet solution for verifiable PDFs.

Lissi is a cutting-edge digital identity platform that enables organisations to establish trusted relationships, and send and receive verifiable credentials, including PDFs. With Lissi, the integrity and authenticity of your documents are ensured, eliminating the need for lengthy verification processes. In this blog post, we will delve into the challenges associated with verifying PDF documents, the benefits of using verifiable PDFs within your organisation, and how this technology is integrated into the Lissi Wallet.

This technology is a game-changer for organisations, which deal with sensitive information and want to secure their customer relationship. In this article, we will focus on the Lissi Agent, which organisations use to interact with ID-Wallets such as the Lissi Wallet.

The Challenge with Verifying PDF Documents

Verification processes of PDF documents can be time-consuming and cumbersome, often involving multiple steps to ensure the authenticity of a document. This can lead to delays and increased costs for organisations, hindering their ability to operate efficiently. Furthermore, these processes are not foolproof, and there is always a risk of human error or oversight, potentially exposing organisations to fraud and other risks.

In a world where trust is paramount and speed is essential, these challenges have created a pressing need for a more secure, efficient, and reliable way to verify PDF documents. Our verifiable PDF feature addresses these challenges head-on, offering a solution that is both user-friendly and highly secure.
