I worked for a big company where security was a big thing. I had to have an ID badge to enter the building. My boss once admitted to requesting the logs to determine if people on the team were really showing up on time to work. So I was aware the information could be used in let's say a predatory fashion for things not immediately obvious.<p>However, I once had an ugly run in with another employee I did not know while in the parking lot. I went to security to look at film and try to ID them. We were not able to ID the employee. We checked film from the stairwell I exited through and caught a glimpse of the person, but you only had to swipe your ID to get in, not to leave. So, no, there was no timed ID badge record to match the picture against.<p>I was surprised by the outcome. Given the ID badges and security cameras, etc, I had expected a Star Trek style set up. No, not remotely.<p>I am well aware info can be used against people. That mostly scares me in cases of hostile intent. And where you have hostile intent, it almost does not matter what info they have. They can spin it as something bad anyway.<p>At this point, I think being innocent is mostly not a defense either. I hope things change. Currently, there is a lot of assumption of guilt and, to me, that is the real problem.
