Rollback is quite appealing but it does leave a window during which malware can exfiltrate your private info before you pave over it.

- stcredzero 9y agoControversially, at least for these circles, I also advocate Trusted Execution as a tool for personal security and the protection of personal information. In the hands of corporations and governments, imposed on individuals, this becomes DRM and is clearly horrible. It's so horrible, there should be laws heavily regulating it's use by organizations against individuals. However, the same asymmetries that make the issues of disclosure and privacy different between corporations and individuals also make trusted execution different between corporations and individuals. It's bad for society and individuals when individuals have their information disseminated against their will. However it's very good for society when corporations, governments, and other organizations are required to be open and disclose information. This is why Trusted Execution should be used by individuals against organizations. Aimed in that direction, it compensates for the power differential. Used as DRM, it exacerbates it. Trusted Execution combined with sandboxing can provide individuals with very good protection against things like malware and the Sony rootkit. My ideal PC would have an inviolate hypervisor kernel supervising an open "dev" VM which can be rolled back, along with various "appliance" VMs where sandboxes with Trusted Execution can protect the individual from the execution of other people's code.
