As in title, i’m just wondering whether it is possible to rip movie from cinema if one has got unsupervised access to cinema’s hardware. Maybe someone did that? I’m not talking about caming, i’m talking about making a digital copy of premiere material.
Now i wonder what it does when battery dies, whether it wipes itself or not. And where it stores it’s keys, in TPM or in RAM or where.
Pretty sure the media itself is stored in ram, or similar volatile memory; so it wipes automatically on powerloss.
Friends in other comments suggested that the file is 100-300gb size, it’s quite a lot of RAM if you asked me, but not much for a harddrive. If i were to design this machnie would store the movie heavily encrypted on a harddisk and store keys in RAM. Sb ealier mentioned you need special keys from special compamy to decrypt it so it would be doubly encrypted, one key stored in RAM and another inputed by technican. Ofc if i were to design this i would try to make it piratable by introducing some “accidential” vuln.
Too many engineers involved, there wouldn’t be a single point of failure like that by design.
