ProofOfOwnership

PoW proof of concept based on the paper Proofs of Ownership in Remote Storage Systems by Shai Halevi, Danny Harnik, Benny Pinkas and Alexandra Shulman-Peleg.

Link to the paper: https://cyber.biu.ac.il/wp-content/uploads/2016/06/207.pdf

Context

Two files are uploaded to the server (an original doc and an original pdf).

Program parameters

  1. Path to file
  2. File hash (real or deceiving one)

Possible outputs

  • If an original file is upload along with its real hasg, the server will return the file (its hash will be shown) after going through PoW protocol.
  • If an original file is uploaded along a wrong/deceiving hash, the server will upload the file (if it exists, the file will be uploaded, if not, the server won't do anything).
  • If a manipulated file is uploaded along with a wrong hash, the server will upload the file (it will calculate the manipulated file hash).
  • If a manipulated file is uploaded along with its hash, the server will upload the file.
