   • works on amazon, ali-express, noon

To replay to a request:

• go to request page, select the category, click on the item to view the description, and click for longer time to send a reply.

To View a response:

• go to replies, click for longer time to see the response, after viewing click on the item again to rate it.

Balance:

• Each user has a balance of 100 by default, and after rating a video, the amount is moved from your account to reviewer account, with 5% deducted.
• Amount depends on the rating + view time.

Security features:

• SSL encrypted communication using public certificate signed by Let's Encrypt Authority X3.
• Passwords are stored after being hashed using SHA-1.
• Database credentials are not stored in the server side directly.
• SQL injection protection: by validation every input in the server side.
• Two way authentication: by using a preshared key for the server to validate the application.

Software architecture:

• the Application is developed in java.
• Server side has php code with MySQL database.
• REST API is used for communication.

Streaming:

• uses RTMP "Real Time Messaging Protocol"
• RTMP is an application layer protocol.
• It uses TCP protocol, port 1935.
• API provided by MUX.com
• provides video and audio from replier to requester only.
• On client side, it uses m3u8 format videos over HTTPS.

Automation part:

• URL parsing: allows the user to directly copy the URL instead of writing the item name.
• Category classification: classifies the items into categories, with the help of data that has almost twenty thousand items.

Current limitation:

• The stream record code has compatibility issues with API 24.

Future work:

• Improve the video quality of the stream
• Add caching to improve speed and reduce bandwidth usage.
• Improve the GUI, and make it more user freindly.
