According to the report, it is said that Apple is upgrading the computer system at some of their factories to determine how long a component should remain on one production station before it moves onto another. If it takes too long to arrive at its destination, security alarms could be triggered.
Presumably the idea is that this is done to prevent components from being stolen or for people on the assembly line to stop and take photos of the components, because since that would take extra time, it could trigger the alarm that something amiss is happening. Apple is also requiring that videos that show the destruction of prototypes or defective parts to be stored for at least 180 days.
Apple, like many companies, have been battling leaks for the longest time ever. However, they were kind of successful recently where they managed to fool some leaksters into making claims that there would be an Apple event on the 23rd of March, which later turned out to be false.
