Then let the corporation (i.e. HR) do the signing and you decide
whether to trust HR's signatures.
Really this should be designed into the corporation rather than pasted
on. The chief security officer should somehow determine what would be
satisfactory procedures for verifying identity for the purpose of
issuing such signatures and get it accepted as a requirement for HR.
Probably this will be designed in consultation with HR so that it will
actually be implemented properly and not be a constant source of
pushback. The meaning of such signatures should be documented and
published internally, so that relying parties know what they are
getting and can decide for what and how far they are willing to rely
on them. Part of the determination should be the purpose and scope of
One factor in the steady drizzle of corporate security failures is
the notion that one can buy a box of security off the shelf and

should work better and be cheaper in the end.
