Today we are pleased to announce the launch of our new decentralised Proof of Ownership service:
crypto-copyright.com Crypto-Copyright.com releases new proof of ownership serviceIn today’s society, where the era of the Internet has taken over the world, proving that an individual was the first to create a file can be quite difficult, especially since once content is published to the Internet, it only takes a couple of minutes for it to appear on other sites, and for others to copy the work and put their names on it.
Well, Crypto-Copyright.com represents an innovative platform which aims to allow users to get their documents certified by a decentralized proof of ownership service, thus clearly removing doubts related to who owns the copyright to a certain piece of work.
With this in mind, once a document is submitted on the site, the service will embed cryptographic hashes of the files, or raw text, directly into the Bitcoin Blockchain, where anyone who is curious can view proof of ownership. At this moment in time, any sort of digital work such as PDFs, MP3s, text documents, and raw text can be submitted for proof of ownership.
While there are other similar services available on the market, this one is unique thanks to the SHA-3 hashing algorithm that is being used. This makes the platform immune to attacks such as length extension undertaken by people who wish to steal the user’s work. In fact, there aren’t any known collisions at this moment in time, which would have the potential of attacking the embedding algorithm. Unlike services which use SHA-2, clients can rest assured far into the future that once their work has been copyrighted, it’s bound to remain theirs.
Another interesting feature is that our users are allowed to submit messages signed with the same bitcoin address used to pay for the service, hence initiating a two-factor cryptographic proof. Once the purchase is finalized, all details will be included into a PDF that users will be able to download at the end of the process.
In terms of prices, Crypto-Copyright has chosen to offer the service at the low fee of 4 mBTC, which is required by the embedding algorithm. This makes the service significantly cheaper than other companies, which require higher fees, while also providing inferior services.
Based on everything that has been outlined so far, Crypto-Copyright.com aims to provide superior proof of ownership services, by quickly inserting the cryptographic hash of the work into the Bitcoin Blockchain, and offering secure and low-cost solutions as well.
What is Crypto-Copyright.com?Crypto-Copyright is a service that allows you to prove ownership of a digital work, this can be anything from PDF documents, mp3's, images or even raw text such as a Poem or Lyrics to a song.
Our service will calculate the SHA3-224 cryptographic hash of your work (client side using Javascript; your document is never uploaded to our servers) and using our embedding algorithm we will permanently and irrevocably insert this into Bitcoins Blockchain.
Our algorithm provides the best security for your crypto-proof by using the latest award winning SHA3 hashing function which helps to protect against possible attacks such as hash collisions and length-extension attacks which other functions such as MD5, SHA1 and SHA2 are vulnerable to.
With the cryptographic hash of your document registered in the Blockchain you can prove with absolute certainty that you were in possession of the digital work at that precise moment in time.
How does Crypto-Copyright.com work?Crypto-Copyright works by calculating a cryptographic hash of your work, this hash is unique to each digital work.
Once we have calculated your hash we append it to our unique bytemarker (CryptoProof-):
43727970746f50726f6f662d <-----> ba8526b316a7c68d90e72f9d643548c6a92a27e370f5cfbb2dcbc384
|_____Our Bytemarker____| |_____________________ Your Hash _______________________|
When we have combined your cryptographic hash with our bytemarker we create a custom Bitcoin transaction using a special OP_RETURN code that allows us to insert the data into a transaction and broadcast it to the Bitcoin network.
How can I prove I submitted the hash?Using two factor crypo-proof mechanisms it can be proven you were the one who submitted the cryptographic hash by signing a message using the Bitcoin address used to send payment to our system.
This signed message will be included in your crypto-proof certificate along with the Bitcoin address generated for your unique transaction and the transaction ID containing your cryptographic hash.
The combination of these three things can cryptographically prove you were:
1) In ownership of the digital work at the time your transaction was included in the Blockchain
2) That you were in control of the Bitcoin address used to pay our service
Thus proving that you were able to calculate the hash and submit it to our service.
Please check your wallets documentation for instructions on how to sign a message with your bitcoin private key.
Feedback is much appreciated and welcomed!
