Blockchain-based data certification company Stampery has added Microsoft Office as a client in their present solution in order to improve their enterprise customer reach.
Stampery verifies documents against both Ethereum Classic as well as bitcoin blockchains through a web page and also through a programmatic API. The Stampery blockchain add-in for Microsoft Office communicates over REST with an Azure Node.js server, which then calls the Stampery API, the Microsoft post explained.
Various enterprise organizations keep important records in Microsoft Office like contracts and legal documents. It is valuable for users to be able to certify or sign these documents, to verify they have not been altered. In order to do this, Stampery creates hashes of documents and sends that hash through the web and storing them on the publicly accessible blockchain, such as the Ethereum Classic and bitcoin blockchains. Stampery provides a RESTful API that is accessible from applications, to enable this capacity.
“In this project, we leveraged this secure API to create a convenient add-in to Microsoft Outlook that performs like a near-native feature to stamp/certify an email without leaving Outlook or even the specific email that you are viewing. The solution provides document certification (creation of a stamp) and verification (checking a document against a stamp) in Office using the Stampery API and the public blockchain,” the post added.
The add-in function is implemented in JavaScript running in Microsoft Office and with a Node.js server. The server offers the REST service to connect to Office functions and to communicate with the Stampery API.
The service enables users to employ the most appropriate, secure method to store both the document and the hash. By doing so, enterprise customers who rely on Microsoft Office can make use of blockchain technology and the Stampery service to confirm the validity of their important Office documents.
