## Video Conference Calls
With the [many, many security issues with Zoom](https://www.tomsguide.com/uk/news/zoom-security-privacy-woes), and other mainsstram it becomes clear that a better, more private and secure alternative is required. As with other categories, the "best video calling app" will be different for each of us, depending on the ratio of performance + features to security + privacy required in your situation.

## Metadata Removal Tools
[Exif](https://en.wikipedia.org/wiki/Exif)/ [Metadata](https://en.wikipedia.org/wiki/Metadata) is "data about data", this additional information attached to files can lead us to [share significantly more information than we intended](https://gizmodo.com/vice-magazine-just-accidentally-revealed-where-john-mca-5965295) to.
For example, if you upload an image of a sunset to the internet, but don't remove the metadata, it [may reveal the location](https://www.nytimes.com/2010/08/12/technology/personaltech/12basics.html?_r=1) (GPS lat + long) of where it was taken, the device is was taken on, precise camera data, details about modifications and the picture source + author. Social networks that remove metadata from your photos, often collect and store it, for their own use. This could obviously pose a security risk, and that is why it is recommended to strip out this data from a file before sharing.

It's possible (but slower) to do this without a third-party tool. For Windows, right click on a file, and go to: `Properties --> Details --> Remove Properties --> Remove from this File --> Select All --> OK`.
Alternatively, with [ImageMagic](https://imagemagick.org) installed, just run `convert -strip path/to/image.png` to remove all metadata. If you have [GIMP](https://www.gimp.org) installed, then just go to `File --> Export As --> Export --> Advanced Options --> Uncheck the "Save EXIF data" option`.
Often you need to perform meta data removal programatically, as part of a script or automation process.
