Fred Trotter: This is a very complicated topic and I would encourage you to look at ClearHealth here, they have a robust object-modification logging system that they have been working on.

Sam Bowen: Clearly, our logging needs serious improvement. That is what started the security discussion with Justin Doiel and Fred Trotter. Justin and I were discussing using an md5 digest in the log to prove that encounter had not been tampered with. We wanted to sign the md5sum, and date time stamp with a public key which could be verified in court that the record has not been altered. Or conversely, in Justin's case, to prove that the record had been altered intentionally. (Not all of his practitioners are as honest as we all assume). The practitioners are not very good at cheating the system. When audited the entire group receives sever legal attention from their state regulators. He wants a tool to be able to keep his practitioners honest in a proactive way.
