Produced by the Blume Corporation, CTOS, or Central Operating System, controls Chicago. The system is the fundamental weakness of the city, as it can be hacked into through the use of a chain of backdoor viruses and used as a weapon against the city and its inhabitants. The CTOS also stores information on each inhabitant of the city in control centers and gathers new information with the help of surveillance. Various control centers (data servers) are dotted around Chicago, which can be taken control of, along with CTOS towers, allowing Aiden to access the information it stores and the mechanisms it controls. Various communication sites are placed between the centers, allowing for quick transfer of data over large distances. Though CTOS has reduced and is still reducing the overall crime levels of Chicago, that doesn't mean that the city is as protected as Blume says it is. CTOS is tied to a satellite which acts as a safety valve which can shut down the entire system if necessary.
One question that is frequently asked about the CTOS is: Who controls the system that controls Chicago? One negative that has been noted about the CTOS is that large businesses could use the data stored by CTOS to maximize profits. It has also been noted that control of the system could fall into the wrong hands, like those of hackers such as Aiden Pearce, Damien Brenks, and Defalt.
The fact that control of CTOS could fall into the wrong hands has clearly been brought to the public's attention by a hacking collective known as DedSec. The collective hacks into the system and misappropriates its abilities to use it for its own purposes, such as invasions of privacy or data collection, simultaneously emphasizing CTOS's great power and security flaws.
