# 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.
