Will data privacy be an issue? Has this aspect been considered?

First of all, thank you for your question.

We are not sure you are concerning data privacy issue on which part.
If you are concidering the privacy issue on the first stage (Data collection process to verify and validate the algorithm from Professor Albert Wong’s team). We believe that we won’t have any data privacy issue as the first stage will only be used by developers (Their team and our FYP project group). Where we the data collection only starts when we press the button and stop when we press the stop button. As mentioned before, the location info is stored locally and only contains designated route (whihc means even there is leakage in data, it won’t create much privacy issue as it won’t contain personal location info)

But if you are considering the data privacy issue after the system launched, we guess the data handling process wil have similar concept as Google Map or other location services. We believe that developers who use this technology will follow the rules such as not recording the info that can classify which person you are.

Please feel free to ask additional questions if there is any places unclear.

I am asking for the later stage. I agree with you that this is a similar situation to other types of platforms (such as Google Map). Anyway, privacy issues are increasingly important.

I agree that privacy issue is an important issue that many projects need to be aware of. Striking balance between privacy and functionality of the algorithm will be a challenging and rewarding task to deal with. However, it seems that we won’t have an opportunity to work on it in our FYP project as it is not in our scope.

Thanks for the question again.

Hello, I’m Ho Chun Yu. I’m wondering did you faced any difficulties or challenges during the project? Could you please tell me how did you tackle the problems?

Thanks for your question. Since we are from ECE but not CSE, we face more problems than we expected when we develop the main part of our app.We need to do a lot of research to understand the principle and method of devloping an Android application on Android studio.

Moreover, we do not have deep understanding of Android Wi-Fi scanning principle during the start of this project. We didn’t realise that it requires a device running Android 10 or above to perform Wi-Fi scanning (Because device running Android 9 or earlier do not allow a high scanning speed). Where it caused more than 10 scanning trials not usable.

Lastly, we still have some technical difficulties to implement the path planning function (GUI) of the app. Where we will consult help from both ECE and CSE TAs to learn more about.

Thanks for your reply. Actually, our project is facing a similar situation as you. we are struggling with the Android application on Android studio. And we spend lots of time finding examples.

How do you store the crowdsource data of Wifi RSSI?

Thanks for your question, some example was given in the top right hand corner of our poster.
To give more information, we currently use txt file format to store the WiFi RSS and IMU data.
For future development, we may develop a database system to facilitate the storage and transmission of the data.
