A technology company best known for its eponymous copier machines may be looking to use blockchain to create digital proofs for documents and other forms of data.
Just last week, the U.S. Patent and Trademark Office (USPTO) published a new patent filed by Xerox in which it outlines a method by which a blockchain (either a public option or a permissioned alternative) could be used to tie types of data (naming images and video as examples) to a certain period in time.
After detailing the use of the bitcoin blockchain for time-stamping purposes – mentioning the Proof of Existence project by name, the application goes on to state:
“According to an aspect of the embodiments of the present invention, there is provided an information processing apparatus comprising: an acquisition unit that acquires feature information of a latest block in a block chain when target data is generated; and a registration unit that registers proof information indicating that the generated target data is correlated with the feature information acquired by the acquisition unit when the target data is generated to a time proof service.”

Vitalik Buterin wants you to know he is alive. In recent years, after it was discovered just how Orwellian a few Western countries had become as regards digital age communications, people became suspicious that the likes of Julian Assange, Edward Snowden, and others had been disappeared. Buterin plays on this, maybe making a clever nod to regulatory capture, in the following tweet:
The 0x… numbers mentioned in the photograph correspond to this Ethereum block. By doing this, Buterin confirms that he is alive at the time of that block – because that information is not predetermined. In doing so, he also demonstrates a powerful way for activists, protestors, and other dissidents facing government, religious, or other persecution to communicate their own proof of life. Of course, the dark side of this is that the same method is pretty useful in things like kidnapping/ransom cases. The analog version would have been the likes of holding a current copy of the Wall Street Journal beside one’s face.

For the first time in history, historical archived data cannot be altered without being noticed.
OpenTimestamps, a project led by Bitcoin Core developer Peter Todd, just made sure the Internet Archive cannot be forged.
Well, sort of. In a blog post published last week, the developer and consultant explained how he used his OpenTimestamps project to timestamp all the Internet Archive’s 750,000,000 files onto Bitcoin’s blockchain. This means that no one — not even the Internet Archive itself — can modify this collection of books, videos, images and other records; not unnoticeably.

Innovators like Blockai , Pixsy , TinEye and Ascribe promise to use decentralized ledger technology to register and protect against copyright infringement. They understand that a public, decentralized ledger like the blockchain is ideal for cataloging and storing original works of art, digital intellectual property, documents, manuscripts, photographs and images, away from any central authority.
Even if the copyright service ceases to exist, there will still be a verifiable copy of the original work on the blockchain.
The idea is simple. Rather than collecting information about the creator and their work and storing it in a centralized database, turning that database into a blockchain and decentralizing it enables everyone to find and use those works in an authorized way. The advantage is that decentralized ledger technology has the potential to provide a much greater amount of trust. A centralized database is only as trusted as as the entity that controls it. If they are compromised or engage in unethical behavior, that trust can be destroyed and the records they hold mean nothing.
However, decentralized ledger technology relies on the trust of the group. As long as the group is still strong and the blockchain is well distributed, the record is still valid even if the entity that created the chain initially is compromise in some way.
That is the blockchain’s greatest strength: that it’s designed to survive when people are unreliable. Whether that failing is business-, ethics- or technology-related, the blockchain can survive.

Within the Microsoft Office environment, users will see two new buttons.
Microsoft has always kept a close eye on advancements made in blockchain technology. Stampery, a service used to certify and verify documents, is of keen interest to them. As a result, Microsoft Office now supports Stampery authentication services. This will bring the blockchain-based notary service to the attention of enterprise clients all over the world. An intriguing development, although it remains to be seen how many people will use the service.
It is good to see Microsoft pay close attention to a blockchain-based service. Especially when considering how the company’s Office solution is used by millions around the world. However, there has always been a problem when it comes to certifying documents in a convenient manner. Microsoft has solved this issue by integrating support for Stampery.
Microsoft Office Integrates Stampery
Cryptocurrency enthusiasts will be familiar with what the service has to offer. Stampery lets users certify and verify documents against the Ethereum and Bitcoin blockchains. This service is available in online form, but there is also an API which developers can access. Microsoft is using this API to integrate this feature into Microsoft Office directly. This means users do not have to leave their Office document to ensure it is a certified one.
