- Artificial Intelligence is increasingly integrated into various applications, particularly by corporations with significant financial resources.
- On-device AI models enhance user experience by providing fast, offline access for tasks like photo filtering and object detection.
- Microsoft's Seeing AI app serves as a notable example, offering accessibility features, including currency detection for visually impaired users.
- Android apps are packaged as APK files, which contain all necessary components, including AI model files.
- The currency detection model within Seeing AI appears to be encrypted, presenting challenges for direct access and analysis.
- Tools like apktool can be used to decompile APKs and inspect their contents, revealing encrypted files and potential AI models.
- TensorFlow Lite is identified as the framework used for running AI models in the Seeing AI app, which facilitates model loading and inference.
- Frida is introduced as a dynamic instrumentation toolkit that allows for the alteration of app behavior and method tracing.
- By using Frida, the author successfully extracted the currency detection model from the app, validating its contents with a neural network visualization tool.
- The article emphasizes the importance of intellectual property rights regarding AI models, advising users to obtain permission before using or modifying extracted models.
