Plausible deniability in vault apps
Decoy modes help against casual coercion and shoulder surfing. They do not make encrypted data vanish from forensic copies. Blopman can open a decoy safe on a wrong unlock instead of advertising failure.
Cosmetic vs useful
A decoy switch labeled in Settings teaches attackers the feature exists. A believable decoy vault with everyday content is more useful under social pressure.
Blopman’s angle
Wrong PIN/pattern can open decoy content instead of shouting “wrong password.” Fill decoys with plausible items.
Stay honest
Do not market decoys as courtroom magic. Pair them with real encryption and cleanup of Photos leftovers.
FAQ
Does a decoy hide vault count forever?
Not against someone with a full storage image. It helps against people using your unlocked UI.
