authentication – Download fingerprint from Android / iOS to the cloud

I am working on a project to use fingerprint / facial recognition to authenticate the user. I do not want authentication to be device-specific. Therefore, you want to download fingerprints and facial images from the user to the cloud.

I have been looking for fingerprint transfer in the cloud and I realized that this link was not possible: https://www.androidcentral.com/how-does-android- save-your-fingerprints # targetText = When% 20you% 20register% 20a% 20 fingerprint, the% 20data% 20% 20the% 20scan. & TargetText = This% 20encrypted% 20fingerprint% 20template% 20is, on% 20your% 20phones% 20encrypted% 20storage

However, this article is old! I need to know if I can download the fingerprint from the device to the cloud (I plan to use an EC2 instance for the backend API.) Registration and can we authenticate the user when the user accesses the application on any device.

I understand that the fingerprint can be considered to authenticate the user on the device using: https: //www.npmjs.com/package/react-native-biometrics which is a safer bet. But it does not serve the purpose

Also, for the face authentication, I told myself that I could use APIs such as res10_300x300_ssd_iter_140000, mobilenet_ssd_face of AlwaysAI or
I can use the facial_recognition & dlib libraries in python to extract facial features and compare. I do not know how long it could take!

I would appreciate any information about fingerprint authentication and facial recognition.

How to keep a Google sheet open for multiple tasks on IOS?

I use Google Sheets on an iPhone X under iOS 13.1.1.

When I:

  1. open a sheet in the native Google Sheets app (that is, installed from the Apple App Store without visiting the sheets.google.com site in a browser Mobile web),
  2. then use another application (not very greedy in memory) for 30 seconds,
  3. then reopen the Google Sheets app (by tapping either the app's icon or swiping the screen to select the app from the list of apps in the background ).
  4. the sheet is no longer open and I need to reopen it and move back to the desired place in the sheet.

Is there a way to have the Google Sheets application keep the sheet open and scroll it to the same place?

I have tested this using the built-in iOS app.

Thank you

The iOS simulator can not access the local apache

My apache setting is below.



    ServerName myapp.localhost
    DocumentRoot /Users/whitebear/httproot/myapp/public
    
        Require all granted
    

    ErrorLog /var/log/apache2/project_error.log
    CustomLog /var/log/apache2/project_access.log combined


I can access the page by browser http://myapp.localhost (Safari, Firefox, Chrome)

However, in the iOS simulator, it does not work.

Safari can not open the page because the server can not be found.

I've searched on Google and I found that the ios simulator can access the local host without any particular problem.

Does someone come to mind the reason ??

ios – Time code in the screen: use a password rather than a 4-digit PIN?

iOS uses a 4-digit access code to secure the screen time settings (formerly restrictions).

Use the time code of the screen

Use an authentication code to secure the time settings on the screen and to allow more time when the limits expire.

I would rather use a random password of more than 20 characters, difficult to memorize and enter. I will store the password and search for it if necessary, rather than easily remembering the Screen Time password.

Is it possible to use an alphanumeric password rather than a 4-digit PIN?


This is similar to the iOS device's master password, which Is allow a more secure entry:

Enter a six-digit authentication code. You can also press Code Options to change to a four-digit numeric code, a custom numeric code, or a custom alphanumeric code. (link)

mobile – How to prevent a scroll bar with scrolling to hide on iOS Safari?

When you add -webkit-overflow-scrolling: touch; For a scrollable element such as a div, for example, you get a smoother scrolling experience (native scrolling), but you lose the ability to scroll the scroll bar continuously. Because for some obscure reason, Apple decided that it was good that the UX was hiding the scroll bar most of the time.

The problem is that when only 3 elements appear in your scrolling content and the rest is not partially cut off, you have no indication to tell users that there is a scrollbar and more items are available.

I would like to know if there is a way to have a scrolling div with scrolling scrolls, but this is never hidden.

interaction design – Exporting assets from iOS and Android

I'm designing iOS and Android apps and using a Sympli tool for developer transfer, which is a tool similar to zeplin's. I need to know which format should I download files for so that they can be used on both iOS and Android.
The fundamental problem that I'm trying to understand is whether we can use our same iOS board dimensions (375 Widths, 1x) to generate consumable assets for iOS AND Android and make sure that these assets match the specifications Design.

finder – Location iOS 13 WiFi Sync

Previously, I could try running a WiFi sync from my phone (iOS 13. 1.2) by going to Settings> General> Wifi Sync.

I do not see this option anymore. On my computer (macOS 10.15), I am at the mercy of the phone appearing in the Finder (just like I did before at iTunes, at the mercy of this one) whenever it hits the phone or the fantasy of the phone. # 39; computer (I'm unable to determine what makes it appear or not.)

Is there a way to tell the phone to start a sync? (or ask the Finder to look and show me the phone that is connected and ready to use when it appears)
