Hi,

I'm using a mobile ISP to be connected to the internet. But my ISP uses data compression for all images sent over http. This would not happen if there would be a https connection or all bitmap files come in as an archive like tar or gz. If this bitmap is not only for showing nice pictures then I would compute sensless data =(
(sorry but I don't where to post this)


Greetings ...

The BOINC developers are aware of this problem. If you visit the BOINC preferences page for any project you're attached to, you can find an option

Skip image file verification?
Check this ONLY if your Internet provider modifies image files (UMTS does this, for example).
Skipping verification reduces the security of BOINC.

Because this option exists, I don't think any project would be foolish enough to send crucial data needed for calculations in an image format (they mostly use .gz format for the important stuff). The bitmaps are purely for entertainment, so it doesn't matter if they get compressed.
