Android & IOS Camera App developer

Job ID: 37536830

Budget: $30 – $250 USD

Need a camera mobile app developed for both android & IOS. The mobile app may require centralized backend system (maybe can build using Laravel). The main purpose is to use the app to shoot photos and we're able to verify the authenticity of the photo using the app. Need a mechanism that can read the image data to verify its originality (no edits/tampered/etc).

Method of verification that i can think of, please suggest me other possible methods:
1. embed additional data secret keys in the photos during photo taken, like a key pair. Secret keys embeded into the photos and the other pair kept on server database. When the image loaded onto the app, the app compare the image key and find a matching key pair on the server, if found matched pair, photo is genuine. If no match means photo is not genuine. So when transferred/editted/compressed/etc, the secret key on the photos will be gone.

2. If (1) is not possible, please suggest other method.

The Function:
1. Able to shoot hi res photo at least 9MP.
2. Able to verify photo originality within the app.
3. Able to retrieve image data like date time taken, location, metadata etc2.
4. Able to support me until the app got published on Apple Store & Play Store.
5. Provide app minor modification/maintenance at least for 1 month after finished.

Please start chat with me with some example of your previous mobile app project.
