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:

• iPhone app - FakeApp
• Google Chrome plugin - nofakenews

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
