I read an article on slashdot this morning. It was about the new authors/coders of a tool that would act similar to SnapChat. The premise seems legitimate, however we live in a digital world. There is no either that data travel through undetected. Even if an encrypted source is transferred to a device, do we think that data is safe whether on the device or traveling through the net? And do we think that even though data will be deleted after a duration, can it still not be captured and cracked? Also, do we trust that these companies are actually 'purging' our data?
