Definition - What does Machine-Generated Data mean?
Techopedia explains Machine-Generated Data
He said that machine-generated data are entirely produced by machines or that the data are more about observing humans rather than recording their choices. The opposing idea is that of Daniel Abadi, a Computer Science professor at Yale University. He proposes that machine-generated data is the result of a decision by a computational agent or a measurement of a process or event that is not directly caused by human action. Whichever the case may be, it excludes data manually entered by a human.
This type of data is amorphous as humans rarely modify this data. It is typically the result or a response to an event which has occurred, so it is often historical. The best example of this is any kind of log. When an event takes place such as a purchase, the computer takes note of this and stores the details into a database and generates a log entry if programmed to do so. Other examples are network logs, equipment logs and call detail records generated by telephony systems. Since these are often historical and less prone to modifications and updates, the US Court System considers machine-generated data to be highly reliable when used as evidence.
