Fascinating! That is exactly what I had in mind. Thanks!

I suppose that now my landscape photos will be suspected data caches on the rare occasions that I get to travel out of the country.

Please note that even if one agent is compromised, the messages to the other seven won't be able to be identified nor decrypted.

Fine. I drew the distinction between difficult and impossible. I also suggested that additional information may be required, which you have now supplied. Given that, rubber-hose cryptanalysis; chequebook likewise; svelte blond{,e} likewise and a number of similar techniques may now be applicable.

so that mean there is 8 file encrypted, whith each a different password?
brute-forcing the password might still be difficult, but hey, there is at least 8 of them... yeah, encrypting non significant file inside a picture is a neat trick too

Particularly the svelte blonds....

Some level of unintended consequences must be occurring with all this ham fisted border handling; even the sheep are learning coded ways to bah! On the other hand (the less ham fisted one) there also must be several intended effects. Even so (the gripping hand), security theater loves a circus -- and clowns. Because there are always clowns. Always. Russia surprised by 'crude, clumsy' US spying

Meet "BOSS": The Department Of Homeland Security's Facial Scanning Program

Ever heard of BOSS? Didn’t think so.

BOSS stands for Biometric Optical Surveillance System, and it is a crowd-scanning program that has been in development by the Department of Homeland Security (DHS) for almost three years now.

Did you catch that? This is the DHS, the ridiculously dangerous, cancerous, gargantuan waste of money our “leaders” foolishly created after 9/11 to prevent “terrorism.” Whereas in the beginning most people actually believed the DHS was there to stop cave dwellers with terroristic tendencies, it is now completely clear that its primary mission is to protect the oligarchs and political criminals from domestic dissent.
