UK government is trying to get into iCloud end-to-end encryption. (Again?)

Makes me think about email servers too. Most of my private information is in emails, and not only I use a service where the host machines access the email, so do almost everyone I email to/from.

LLO, but this isn't the way how steganography works. In a photo any pixel has a hex value, a minimal change to another value of one or some bits can't be seen by an human and so the change of several pixels to an predefined value can hide an message, beeing invisible by sight, but readable by an corresponding app.

    I know, but I liked the idea of sending messages by interpreting meaning in a series of cat memes :-)

    By the way, do you know if steganography in an image is truly undetectable? Or if an attacker could, by statistical analysis or pattern analysis, determine that steganography has been used?

    It's not so easy to detect a steganographic message in a photo, soundfile or video, it's only detectable with specific apps. But the main reason is that goverments and security services first need a suspicion that these cute catphoto or an selfi of this guy in a beach is an secret message to make this analyse, much more likely to be suspicious of an encrypted message not feddable. This is surely more interesting to perform an in -depth analysis, instead of wasting time with thousands of vacations, selfies and kitten photos or analyzing the sound archive of your son playing Happy Birthday on his flute.
