FakeAPI

An API to collect and process people's opinions about news they see on the internet and determine their authenticity. People create a reputation based on their opinions and this reputation affects on the algorithm that determines the news veracity.

Collaboration:

This project is to integrate with an open source blockchain

Two projects are currently being implemented to consume this api:

Installation

Clone the project

$ git clone https://github.com/BrunoScheltzke/FakeAPI.git

Get Node

Download or install from your prefered package manager

Install the dependencies

  • $ npm install got
  • $ npm install --save form-data
  • $ npm install express
  • $ npm install body-parser

Run the project

$ node fakeapi.js

API

The project is currently being run at http://localhost:3000/ with the following endpoints

Create a block

  • /createBlock - POST

    A POST method at to enable the creation of a block in the chain.

    Call this method before adding any transaction to establish an identification. A block is created using a public key - RSA 1024

    Parameters POST body

    arg: Dictionary

      userPublicKey: base 64 str
      (The public key - RSA 1024)

    Returns

    arg: Dictionary

      aesKey: str
      (The 32 bytes AES server communication key encrypted using raw RSA with the given public key)

    --

      500 Error - For Invalid key format

Adding a vote

  • /vote - POST

    A POST method at to enable the creation of a vote

    Before adding a vote, it is necessary to create a block in the chain (by making a POST request at /createBlock) as a vote is represented as a transaction inside a block.

    Parameters POST body

    arg: Dictionary

      userPublicKey: str
      (The public key(RSA 1024))
  encryptedVote: str
      (A dictionary encrypted(AES CBC Padding PKCS7) with the 32 bytes 
      AES server communication key(received after creation of block))
          vote: base64Encoded str loadable as json dictionary)
              userPublicKey: str
              vote: Boolean
              newsURL: base64Encoded str
          signature: base64Encoded str
              (The vote dictionary signed with the private key(RSA 1024))

    Returns

    • 200 - Success
    • 500 - Error with statusMessage indicating error
      • 11 - No block found for given public key
      • 12 - No communication key (AES) found for given public key
      • 13 - Invalid signature

Verifying veracity of news

  • /news/:newsURL - GET

    A GET method to enable verifying the veracity of news

    Parameters Get

    ars: base64Encoded str
   (the news URL)

    Returns

    The veracity of news (Content in development)

To do list:

  • Create endpoint to accept a vote to news
  • Create endpoint to verify the veracity of news
  • Algorith to verify user's reputation to determine veracity of news
  • Integrate with open source blockchain This will require modifications on blockchain project
  • Determine user's signing keys approach
  • Determine users' reputation approach based on existent reputation researches
  • Determine news veracity approach based on existent news veracity reseaches
