Documentum allows users to store their files hashes on Ethereum blockchain. The files hashes acts as signature, other users can later compare their files hashes with the hashes on the smart contract, this permits with 100% precision to see if two files are identical.

Advantages of Documentum:

  1. Only hashes and file titles are stored, so the transaction will be cheap
  2. Privacy, no one can know or see the content of the documents, the hash does not give any information about the content
  3. Fast, the calculation of the hash is done client side using asm crypto
  4. Easy to use, users need only to load a file and see what happen

If you want to see Documentum open source and on the public ethereum network just donate ether to:
