<p>As far as I know Bitcoin Blockchain can be accessed via API to enter data.
In this case I want to generate a hash/ Checksum MD5, that cannot be understood by anyone that doesn't have the private key, and store it blockchain. </p>

<p>Give to the client the ID of the blockchain's record where hash is stored and the private key of the hash, would be ok, to ensure the ownership, immutability, and also the privacy of the stored data (a hashed .pdf file mostly)?</p>

<p>Thanks!</p>

# Blockchain to store private data and ownership

(Asked by: username_0 on 2017-09-07)

As far as I know Bitcoin Blockchain can be accessed via API to enter data.
In this case I want to generate a hash/ Checksum MD5, that cannot be understood by anyone that doesn't have the private key, and store it blockchain.

Give to the client the ID of the blockchain's record where hash is stored and the private key of the hash, would be ok, to ensure the ownership, immutability, and also the privacy of the stored data (a hashed .pdf file mostly)?

Thanks!
