This can be done using regular user:group permissions. Let's say
you run the service under a specific user "service" ; let's
furthermore say that Bob's user data is owned by bob:bob. Then
you just have to make user "service" a member of the group "bob"
and set the file attributes to rw-/r--/---, for example: user
can read and write, service can only read, nobody else can do

In this case, the password of Bob doesn't even have to be known
to the service. Locking and unlocking is a matter of group
menbership. This is controlled by the system administrator.

Oh, and an additional approach is using ACLs. Here, the user
himself can "unlock" things easily, if desired.

There are probably many other ways that make such a way of access
control possible.
