Another system that had similar goals and was developed quite a long time ago (between 1997 and 2000) was rubberhose[1] by Julian Assange, Suelette Dreyfus, and Ralf Weinmann. It had the additional goal of being designed so that if you were forced to decrypt the drive, it would be impossible for the attacker to know if there were more subvolumes to decrypt (a precursor to how VeraCrypt subvolumes work). However you should be aware that this property is not widely considered a "good thing" because if you are in a situation where an attacker is willing to physically harm you, then they may not be convinced that you've given them all of the keys (even if you have). The same problem exists for cryptosystems that self-destruct -- how do you convince the attacker that you weren't the cause of the data being destroyed?
