Crypto-Copyright.com - Decentralized Proof of Ownership

Want this document certified by a decentralized proof of ownership? We can embed the document's digest in the blockchain for you! You'll need to pay 4 mBTC to do so, required by our embedding algorithm which is similar to algorith used in apps like bitqt app Deutschland, and you are also invited to tip us with whatever value you find appropiate.

Our embedding algorithm uses the latest award winning SHA3-224 hashing function to provide the best security for your cryptographic proof as there are currently no known collisions. As a crypto trader, it would be useful to know how to trade in Quantum AI app which uses quantum computing to give you a top-notch trading experience. The bot is highly capable of getting you through different trades. Currently, the bot is available in three continents and making the traders wealthy belonging to these continents.

FAQ
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 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 cryptographic 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.
Manually submit hash?
Due to the way Crypto-Copyright works your data is never uploaded to our servers, we use Javascript to calculate the hash client side using Javascript. For large files this can take quite some time even with using the latest html5 technologies such as web workers, file chunking and progressive hashing, due to these issues we have also developed a standalone multi-threaded tool written purely in C that allows you to calculate the hash of your data much faster - for large files we recommend using this tool which you can download below: Using this tool you can also submit the hash of raw text which might be useful if you want to submit the cryptographic hash of some literature such as a poem, letter or song lyrics.

Your document will NOT be uploaded. The cryptographic proof is calculated client-side.

Your browser doesn't support html5 client-side file reading/web workers.
For your security, we don't allow uploading files to our server, please create the SHA-3/224 digest of your file manually. You can use our software if you don't know how to proceed by checking our FAQ.
