Signed PDF

Signed PDF

The importance of security, confidentiality and authenticity takes on a new dimension in today’s digital world. As vital information is delivered via email or a web portal, how can you ensure that customer confidentiality is maintained and that a document is not tampered with or viewed by the wrong person? How can you enable electronic communication and transactions that are in compliance with current regulations such as HIPAA, Dodd Frank, the Fair Credit Reporting Act, and other guidelines?

CrawfordTech’s Signed PDF is an easy-to-use tool that lets you automatically apply a digital signature to your PDF output. By using industry standard digital certificates, you can assure your customers that the information they are receiving is accurate and is coming from a known and trusted sender.

How it Works

When PDF output is created from any Crawford Technologies solution that creates PDF or converts other formats to PDF, the contents of the PDF are read and used to automatically calculate a hash. Most commonly used cryptographic hash algorithms are supported, and it can be easily integrated with a third party cryptographic library.

The hash is stored, along with the customer’s public key, within the PDF as the signature. When opened, the contents of the PDF are validated by calculating the document’s hash, using the embedded public key, and comparing it to the hash within the digital signature.

The digital signature verifies that the contents of the PDF have not been modified, and that document metadata such as date created, author, title and other content has not been changed. It can be used on its own, or in conjunction with standard password security on the PDF file. And if the PDF has been tampered with, the digital signature will become invalid, and your customer will receive an alert.

Benefits

Your customers will be confident that you are taking every precaution to protect the integrity of the critical documents and correspondence you provide to them. You will be in compliance with regulatory requirements and will avoid the risks and costs of security related claims.
