Cryptowerk Introduces Blockchain-Based Technology to Certify Data Integrity of Digital Assets

November 12, 2018


Cryptowerk HORIZON SEAL verifies that assets have not been altered to ensure data can be trusted

San Mateo, CA — Nov. 13, 2018 Cryptowerk, a data integrity company using blockchains to authenticate digital assets, today introduced Cryptowerk HORIZON SEAL™. Cryptowerk HORIZON SEAL is a blockchain-as-a-service (BaaS) solution that creates an immutable seal for any form of digital assets. The cloud service writes digital seals or “fingerprints” of the data to one or more blockchains at speeds of up to one million times per second, creating a tamper-proof chain of custody that can be used in large-scale enterprise applications. With the digital seal, every product, process and transaction can now be matched to its original to verify proof of integrity.

To date, the industry has been focused on unauthorized access of data. Recent events and new applications for technology demonstrate the need for data integrity, a way to detect and deter data tampering. Rather than just exfiltrate data, hackers can tamper with data to serve their purposes. One study says that by 2020, 50 percent of organizations will have suffered damage caused by fraudulent data and software. It’s not just about unauthorized access; companies today must safeguard the chain of custody for every digital asset.

“It’s no longer sufficient to know that your digital assets have been hacked. If you don’t know what’s been done to them, they’re essentially toxic,” said Dirk Kanngiesser, co-founder and chief executive officer of Cryptowerk. “Businesses must be able to verify that their data is unaltered and pristine. As a result, companies are able to do business with each other in a trusted, secure and auditable way.”

Cryptowerk HORIZON SEAL creates a digital seal of each asset based on customer-generated SHA hashes, which is then stored on any public, private or hybrid blockchain. The original data stays private and is never accessed by Cryptowerk. Cryptowerk HORIZON SEAL aggregates hashes and bundles them so that only a single small transaction is written to the blockchain. A digital seal for each hash is returned to the customer which provides immutable proof that the hash is anchored in the blockchain. With that seal and hash customers can directly verify the integrity of their data at any time in the future without Cryptowerk’s involvement. Using Cryptowerk HORIZON SEAL, internal software teams and software providers can easily develop client-driven data integrity applications with no blockchain expertise required.

“When transmitting digital documents via our Next Generation Document Exchange (NGDX), our customers need to know that the documents have not been purposely or inadvertently tampered with during the transmission process,” said Stephan Leschke, chief executive officer of Ferrari Electronic AG. “The ability to provide a Cryptowerk HORIZON SEAL to the shared digital assets builds and reinforces trust between business partners using the Ferrari electronic NGDX system.”

Blockchains have been criticized for being slow, expensive and complex. Cryptowerk’s high-scale sealing technology solves those issues, enabling Cryptowerk HORIZON SEAL to write up to one million transactions per second to any blockchain at a fraction of a penny per transaction, even to Bitcoin and Ethereum. In fact, Cryptowerk as a default writes to both of those blockchains in parallel for maximum reliability and redundancy.

Cryptowerk HORIZON SEAL integrates easily into existing environments, connecting quickly to cloud services like Amazon AWS, along with internal enterprise applications, databases and document repositories.  It also supports the development of new applications for digitally sealing documents, data streams, images and software.

Starting today, Cryptowerk HORIZON SEAL will be available as a free trial, as well as via subscription licensing for production deployment.
