The device would require a quantal scan to key into someone's personal timeline, which can conceivably be avoided if you manage to thwart the efforts of any reporters attempting scan you in public.

[He holds up his hands to the viewscreen to show the size of the devices.]

It's unlikely that they managed to miniaturize the scanning devices any more than I did, so their scanning attempts will possibly be conspicuous.

However, if you're asking if there's some other method of blocking them from keying into your dimensional signature if they do manage to obtain said scans...that would be a no.

[Sheepish.]

I purposefully designed the scanners and the dimensional indexing process to be effectively unblockable.

[His eyebrows raise and he perks up slightly.]

The upside is that since this is almost certainly my intellectual property, I can probably have it confiscated by the Science Police.

[His face falls again.]

However, since I never formally registered a patent or schematics with the UP government, that...may present some challenges. It's most likely going to require a lengthy court arbitration wherein I'll have to use my notes and other files to prove I invented it.

[Whups.]
