I want to share photos with family and friends, but I dont want the photos to be exposed to the internet indefinitely. I am thinking I could use either SafeMonk or BitTorrent Sync. SafeMonk would have my photos encrypted and I would be able to revoke the ability to access them when I want to. But the photos would be in the cloud (though encrypted) and I don't know what level of paranoia is reasonable these days really. On the other hand I could have BitTorrent Sync which would also be encrypted and would avoid the cloud. It feels more private being decentralized. But I would have less information about who is accessing the photos. With SafeMonk only the people who I intend to show the photos would be able to access them and I would have confirmation about who is accessing them, etc. Whereas with BitTorrent Sync anyone who finds out the secret key would be able to access the photos. Any ideas, comments, subtle things I have forgotten?
