The Cryptium Edge
Cryptium Logo

A typical cloud storage provider either 1) doesn't encrypt the files at all, or 2) encrypts the files in storage but can access them anytime because they have the key. That means a rogue employee can look at your files, or an over-reaching government agency can obtain those files in secret.

Software made by Cryptium takes your privacy and security to the next level. Encrypted files stored in Cryptium Docs are only accessible when you are signed in. When a contact to whom you sent a file signs in to download it, only the file that was shared is accessible, and not the rest of your files.

How do we identify leaked documents?
Cryptium Logo

Due to our privacy-preserving design, we don't keep a readable copy of your document for comparison. Instead, at the time you upload or share a document, we generate a set of cryptographic signatures of your document. These signatures are generated using special algorithms known as "one-way hash functions", and they can uniquely identify portions of your document in addition to the document as a whole.

These algorithms are known as "one-way" because it's extremely difficult to reconstruct the original document from them. We only use modern, strong, one-way hash functions recommended by expert cryptographers.

We partner with Cyb3r Operations to monitor the surface, deep, and dark web for copies of your documents, identified by their cryptographic signatures.

What is dynamic watermarking?

When you use dynamic watermarking, we automatically add a unique and invisible digital watermark to each copy of a document you send. This saves you a lot of time compared to doing it manually. We then monitor the surface, deep, and dark web and send you a leaked document alert if we find unauthorized copies of your document. We can identify the source of the leak using the watermark. This is great for private and confidential documents that you have to share with clients, investors, and vendors -- with or without an NDA.

What is download pay-wall?

If you are a professional and you invoice clients for your work, you probably had a client try to stiff you on the payment at least once. The download pay-wall ensures clients are current on their balance due before they download the final deliverable. If your business involves selling digital copies of a document such as a report or e-book, you can collect payment when customers download their authorized copy. You can also allow customers to return and download their copy again. Each copy is watermarked so you can trace unauthorized copies to their source.

What is geo-fencing?

Enterprises often do business with customers who may be in foreign countries, or have office locations around the world. Governments are increasingly passing laws requiring certain kinds of private information to be stored within the same country or only in countries that use the same information security framework. It's easy to stay compliant with these requirements using Cryptium Docs. You can create geo-fencing policies to ensure that all geo-tagged documents stay within their region, and generate document access reports for compliance audits.
