Survey123 signature file security

[AdrianDoss]

Survey123 allows users to add a signature but this is stored on the device as a plain image file, potentially allowing others to view and copy it. Is there any way to secure signature files or remove them after sending the survey form?survey123. #app security

Hi Adrian,

What version of field app are you using? The Inbox and Sent box view/edit/copy data to new survey does work slightly different in 3.9 and 3.10 but with signature question. As you described, signature is an image and user won't be able to see image file in Inbox due to the limitation. And with Sent box, user can see the signature but the send box is only limited to the local device and when copy data to a new survey, the image of signature won't be copied over, either. Your concern of copying the signature from Sent box or Inbox and viewing the signature from Inbox would be possible with the current version of field app.

If you are seeing that signature copy/viewing issue, please let us know and specify the version of the field app you are using, so that we can check this further.
