The Privacy Subcommittee coordinated a broad expert panel of speakers who taught us something of the potential threats to businesses who depend on data and how reliable it is. A few photographs were used to demonstrate some visible data integrity concerns -- The manipulation of photographs. We took a quick glance at some famous photo manipulations found on the Wired News site. Then Ted Claypool showed us a few examples of his own manipulations, including the photo at top which shows him as a member of a recent space shuttle team. (He's the Canadian team member on the top right by the way. Not.)
Our moderator was Ted Claypoole of Womble Carlyle's Charlotte office. Panelists were Mary Ann Davidson, Chief Security Officer of Oracle Corporation; Francoise Gilbert of IT Law Group in Palo Alto; Paul Doyle of ProofSpace, Inc.; and John Tomaszewski, the Vice President of Policy and Compliance at TRUSTe, the online privacy advocacy and certification organization.
Skipping past the fun stuff, we moved on to discussing how these issues may impact real data. As we have learned in past discussions about data security, data integrity is often more a matter of tracking what has happened than it is preventing that which probably cannot be prevented.
Of course, the panel first tried to define what it was talking about when it spoke of data integrity, something we all want but don't necessarily know what it is. The panel did agree that access/security is not the same thing as integrity, and that helping integrity does not mean the data is any more useful (or not) as Garbage In/Garbage Out still applies. Consensus seems to be that integrity is more of a question of consistency and the ability to link the data's state to a particular point in time.
The lawyers on the panel were more in line with the idea that showing that access had not happened would subsequently be evidence of integrity (the thought being that if nobody was in the room nobody could have changed it). The technologists felt that proof of access (or lack thereof) would not be the point, since we need to focus on somehow comparing the facts at one point to the facts on hand today that we purport are the same as the ones put in the room.
The number of questions from the audience spoke well to the interest in the topic.
