By and large we've started to ignore digital signature validation. It' sbecome a pain when you need to update some small clerical item like a typo. Under the archaic version of wet signatures, a clerical alteration was easily handle, you just did it. No one came around with their white-out to clear their signature and resign. So my proposal is two fold:
- Allow one of the signers (doesn't matter which) to get a prompt saying "I swear on this digital book of desired religious importance that the changes made herein are of a clerical nature and have not altered the technical content in any extent from the original signing." or something along that line. The premise here is the honor system, which is still present in our digital sign off world. Not the Digital Signature has a record of someone saying, changes were made but they are acceptable.
- Allow Bluebeam to auto authenticate if the % deviation is small. Signed file 3429kb, +/- 170 kb change is acceptable. of maybe less. At the end of the day we are still operating under the honor system. If the responsible agent/engineer is maliciously circumventing the system this will show up in other areas. And as I indicated we are largely ignoring Digital Signature validations.
This is my thoughts on digital signatures, which i mentioned to you before @Luke Prescott, just logging it here.
For some of our regulatory bodies, the digital id's don't show correctly so in many instances we actually convert our final deliverables to images for submission (so the stamps and signatures show correctly, this isnt' a Bluebeam issue, the regulators are using sub par viewers).
