the timestamped digital seal.
What is CB Blockchain Seal for SharePoint?
CB Blockchain Seal for SharePoint is the ready-to-use solution for Microsoft SharePoint that allows you to digitally seal the documents you store in SharePoint using Blockchain technology.
This works with virtually any kind of document or file. You can apply digital seals to:
Office documents (Word, Excel, PowerPoint)
PDFs and other Documents
Invoices and receipts
Contracts and paychecks
Machine or sensor data
Academic documents, like PhD or Master Thesis
Pictures (.jpg, .png, .tiff, .psd and others)
Music & video (.mp3, .mp4, .ogg, .wmv, .mov)
CAD/CAM files or other professional plans
For all these types of files, you can prove no one tampered with the document from a certain moment onwards and ensure its data integrity. The fact that the digital seal is timestamped is essential, for example, to protect intellectual property.
This works both for SharePoint Online, Office 365, or if you're still using SharePoint Server on-premises (2010, 2013, 2016, 2019).
What can I do with CB Blockchain Seal for SharePoint?

Accelerate your business data compliance
How does it work?
Simple for the end-user
Have all SharePoint documents automatically sealed or, alternatively, digitally seal each SharePoint document with a click of a button. That is all you will have to do as an end-user.
Complex yet super-efficient behind the scenes
A lot happens behind the scenes to make it that simple for you. CB Digital Seal for SharePoint creates a hash - a digital fingerprint that is unique to the file and then sends it to CB Digital Port of Trust.
This unique hash is a seal that is created for the document. It proves that the document had a specific look and content at the moment of sealing.
CB Digital Port of Trust then creates a Super Hash from the hashes of multiple documents. Finally, this Super Hash is sent to one or more blockchains. All this is happening in a super-efficient way - you can write up to 1 million transactions per second.
When you want to prove the document’s authenticity, the hash is recreated so it can be verified in the blockchain. This can be done any time in the future, there is no limitation for older documents.
The original document data is never stored in the blockchain, only the document's hash. Using a distributed ledger makes the solution decentralized and provides the highest possible security, efficiency, and compliance.
