This project draws heavily from two other projects: one called Rewind and another called Windows Recall. However, unlike both of them, Memos allows you to have complete control over your data, avoiding the transfer of data to untrusted data centers.
In short order, this will create a large corpus of unsecured local data.
Is the user expected to secure the data independently?
Do Recall/Rewind help the user to filter recorded data for retention or deletion?
However, I still have a question about this: it seems that lots of hard disk is already encrypted. After all, I also store a large amount of personal photos, documents, bills, and other important information on my computer, and I haven’t meticulously encrypted all this data again. Should I be doing that?
Full disk encryption targets a different threat model - disk encryption protects against someone grabbing your computer.
Writing into an encrypted blob on disk adds a layer of protection against bad actors exfiltrating data by running code on the laptop.
Overall I really am amazed that this sort of thing is now possible and appreciate a privacy-aware / local compute and storage version of it!
