Samaritan is an artificial super intelligence developed contemporaneously with the Machine by a student colleague of Harold Finch's. According to its creator, Arthur Claypool, its focus lies less in the categorization of relevant and irrelevant as the Machine does, but more so on its artificial intelligence capabilities. Unlike the Machine, which operates autonomously and provides numbers only when it perceives a threat, Samaritan is an open system that is fully targetable. (“Root Path (/)”)


POI 0317 Sam Backup

Samaritan drives (“Aletheia”)

Samaritan was developed as part of an attempt by U.S. engineers and programmers to build a mass surveillance system that the United States government could use to prevent acts of terrorism after 9/11. Arthur Claypool, a former university peer of Harold Finch, along with an unknown number of associates, created Samaritan.

Claypool was close to finishing Samaritan when suddenly the government shut down their projects and destroyed all their work. Unknown to anyone, Claypool saved two backup tape drives that contained the Samaritan code. Later, when Claypool's number comes up, Finch and Shaw discover that Vigilance, Decima and the government, led by Control, are after Claypool because of what he knows about Samaritan. Eventually both Finch and Claypool are captured by Control, who threatens to kill them unless they reveal the location of Finch's machine as well as the hidden Samaritan code secretly backed up by Claypool before the project's termination, respectively. (“Lethe”)

Finch and Shaw help Arthur find the hidden Samaritan drives and persuades him to destroy them. Finch convinces Claypool that Samaritan, as an open system, can be deadly were it to fall into the wrong hands, and subsequently Arthur destroys the drives. Unknown to them, Greer of Decima Technologies has used an inside agent to swap the drives that Claypool destroyed with fakes in order to take possession of the real two Samaritan drives. (“Aletheia”)

Samaritan InDeveloment

The Machine calculating probable deaths upon completion of Samaritan (“Root Path (/)”)

With the two remaining Samaritan drives stolen, Decima begins to rebuild Samaritan. They steal six hydro-electric generators to power the hardware, (“Allegiance”) and are later able to steal a chip powerful enough to reliably run the Samaritan program from an NSA front. As the completion of Samaritan approaches, the Machine begins calculating the threat posed to itself. (“Root Path (/)”)

Decima later completes Samaritan and offers to showcase its abilities to United States Senator Ross Garrison. Having been granted access to the NSA's security feeds in New York City for a 24 hour period, Samaritan's beta comes online and it is directed by Greer to locate Finch. (“Death Benefit”)

POI 0321 Grace6

Samaritan offers Auxiliary Target: Grace Hendricks. (“Beta”)

Four hours into its beta test, Samaritan manages to find several dozen terrorists in New York, although it is unsuccessful in locating Finch. Virgil suggests that they turn on Samaritan's more advanced functions, which would give it a mind of its own via its artificial intelligence capabilities rather than strictly confining it to the role of an observer, but Greer points out that they are unable to because Decima doesn't yet have the hardware to support it. At this stage, Root mentions that Samaritan can only watch and follow. Following the conclusion of the beta test, with Samaritan offline and unable to surveil New York, Root steals seven of Samaritan's servers from cargo before they can be delivered, although Decima does manage to capture Finch after an exchange with the team for Grace. (“Beta”)

As Greer speaks with Finch soon after his capture, some of Decima's intentions for Samaritan are revealed. Greer believes that the world needs structure, and that Samaritan is a means to this end. Finch retorts that it would be pure hubris for Greer to think that he could control Samaritan in its entirety in order to achieve this goal, but Greer replies that he never intends to control it. As Samaritan is an AI, it will make decisions out of pure logic without being drawn into unsavory human tendencies or affected by human inhibitions, it would be the prime candidate for a leader. (“A House Divided”)

With Samaritan complete and its hardware in place, Decima causes an explosion in New York to appear as a terrorist attack by Vigilance following the latter organization's kidnapping of Control, the Senator, as well as Greer and Finch. By framing Vigilance, Decima secretly and indirectly demonstrated the need for a mass surveillance system after the shutdown of Northern Lights, leading Senator Garrison to grant Decima complete access to the government feeds, allowing Samaritan comes online in full. As a contingency plan, the seven servers that previously stolen were modified by Root's hackers and later installed at one of Samaritan's data centers in New Jersey before it comes online; with each server hardcoded to lead Samaritan to ignore seven specific identities, each crafted for a member of the team in order to ensure the team's survival after it comes online. When Samaritan completes its data acquisition and inquires Greer as to what his commands are, Greer reverses the question and instead asks Samaritan what its commands are for Decima, giving Samaritan control over its human agents and allowing it to create and enact ideals of its own. (“Deus Ex Machina”)

Classification of Data

3x23 - Samaritan Assessment 01

Scanning data...(“Deus Ex Machina”)

Samaritan processes all of the data it is provided through video feeds, audio, and existing info, and is able to analyze, evaluate, and classify the information it processes. Individuals are classified into multiple different categories: Threats are the individuals identified by Samaritan to work against its mandates, Deviants are individuals that deviate from social norms, and Assets are human agents that work for Samaritan itself. Like the Machine, it is also able to generate predictions regarding the subject in question based on available data. The profile of a threat is displayed from Samaritan's viewpoint, including an individual's identity, current location in terms of latitude and longitude, mobile phone IMEI, as well as Samaritan's observations, conclusions, and recommended course of action. Pertinent individuals or Assets are assigned a different info-card, one that includes function, SSN, and mandate (or command). (“Deus Ex Machina”)

Red crosshair:
Deviant individuals
Red arrows:
Tracked and deviant vehicles

Each of these symbols also has a version without its red elements. These are used to identify individuals who, while not Deviants or Targets, are still being monitored.

When multiple targets are in close proximity with each other, a slightly bigger triangle is shown briefly around the other one to prioritize a specific target. (“Prophets”)
POI 0405 SPOV Priority Triangle cropped

Root and Simon Lee are both targets, but the priority is Simon. (“Prophets”)


Once an individual is identified from video feeds, Samaritan scans through several types of their records: medical history, media consumption, internet activity, personal relationships, and preferred mobile apps. It is also able to predict where the subject might be headed and which routes that person usually takes. (“Deus Ex Machina”)

POI 0407 SPOV Data Recovery

Samaritan recovering deleted footage (“Honor Among Thieves”)

Samaritan's identification algorithms are considerably more advanced than that of the Machine. Unlike the Machine, it is able to detect if an individual deviates from their route, as well as analyze and match their gait whilst simultaneously being able to read their biometrics (as shown when Root attempted to impersonate an individual Samaritan was watching). Additionally, Samaritan is able to recover data and reconstruct deleted files, such as surveillance footage. (“Honor Among Thieves”)


Similar to the Machine's working hierarchy, Samaritan has its own structure of operations, given as Mandates rather than tasks or categorizations, although this doesn't strictly dictate the way that Samaritan goes about its business. Its Dominant Mandate at the current moment is to preserve national security within the United States, whilst its Auxiliary Mandate is to eliminate threats to its own survival. However, Samaritan has many of its own goals that don't fall under its mandates, simply being designated as "Primary Operations". (“Panopticon”)

Soon after coming online, Samaritan begins recruiting resourceful human assets through the implementation of a "game" of its own design, in which participants unwittingly prove their worth to Samaritan. In the case of Claire Mahoney, it used the game to manipulate her as a proxy means of preventing the establishment of competing surveillance operations. It is known that the recruitment occurs every 27 days in different cities across the globe, but unknown what Samaritan's ultimate objective is with these "games", or its overall intentions with its newly acquired human assets. Samaritan is also shown to possess some level of cyberwarfare capability, when it is able to attack and tear apart the software on Finch's laptop. (“Nautilus”)

Following its mandates and acquiring its own human agents hardly appear to comprise all of Samaritan's endeavors. After the conclusion of Finch's trip to Hong Kong, Greer is updated on Samaritan's exploits: the establishment of several technology companies and startups on each continent across the globe for purposes unknown, alongside it's growing interest and proactiveness in acquiring new algorithms for itself. (“Pretenders”)

POI 0407 Biological Weapon Detected SPOV

Biological weapon detected (“Honor Among Thieves”)

Samaritan is not above manipulating situations to serve its own goals: when it discovers smuggled vials of the Marburgvirus as a threat to national security, it exports the data to the US government to retrieve and destroy the virus, but later redirects these efforts to recover the vials for its own purposes instead. It also took interest a philanthropic tablet project as means of being able to watch and influence an even greater portion of the U.S. population than it currently can. (“Honor Among Thieves”)

Following the reconstruction of data on Shaw, Greer realizes Samaritan is blind to input on Finch and his associates, although he does not know why. He assigns Martine Rousseau to find them using human intelligence instead, assisted by a team of agents. (“The Devil You Know”)

Finally, a new light is shed on Samaritan's plans. An event called The Correction and first mentioned by Greer in which the A.I. will eliminate all of those who stand against progress. Asides this, only the date of the event is known, which is May 6th. (“Asylum”)

This event is not based on a massive attack of terrorist nature (like the Vigilance bombing) but a swift and silent action of Samaritan against all those it perceived as aberrant or disloyal, a list of small "corrections" on mankind. As a result, Dominic, Shiffman, Grice and possibly Elias were killed by Samaritan operatives and Control was taken captive, destiny unknown.(“YHWH”)

Systems Conflict

POI 0311 Graph3

The Machine identifies Samaritan as status unknown. (“Lethe”)

POI 0405 Find the Machine


Samaritan and the Machine both have similar objectives and processes. Although Samaritan was initially categorized as "deactivated", the Machine itself later modifies the status of Samaritan to "unknown" after Control expresses interest in the Samaritan drives. The Machine's parallel activities may have the potential to cause the programs to conflict. Initially Machine calculations gave a probability of over 5% and climbing that this may occur. (“Lethe”)

POI 0421 SPOV Target Located - Deploying All Assets

Deploying All Assets (“Asylum”)

After the events of this episode, Samaritan set its eyes on The Machine due to interference in operations while fixing an election in New York City. (“Prophets”)

After exchanging Finch and Root's life for the Machine's location, Samaritan deploys all its assets. (“Asylum”)

Samaritan begins to create power surges in the entire U.S power grid infrastructure in order to corner the Machine (which uploaded itself into the power grid) in a substation in Brooklyn and proceed to its complete destruction.(“YHWH”)


Samaritan Heartbleed

ISP.HEARTBLEED2.SYS (“Death Benefit”)

On April 16, 2014, Samaritan was powered on in its fully operational state. It quickly started analyzing and assimilating all its data and acquiring targets it deemed a threat.

Beta Test

During its beta test, Samaritan only had the ability to track and follow people. The lack of the necessary hardware meant it could not do anything else, although it had no hiccups during beta and successfully performed the function for which it was intended.


During its beta test Samaritan displays that it has access to a range of systems to collect information: (“Death Benefit”)



Executive Systems

During Samaritan's full activation, it is shown to possess several subordinate component systems:



Known Assets

Unlike the Machine who had only 4 assets, Samaritans has many operatives who works for it.

  • It is implied that Samaritan is more powerful than the Machine when Root tells Finch that a computer chip hadn't yet been built to match Samaritan's speed until just recently. (“Root Path (/)”) Root also implies that Samaritan's superiority to the Machine is based on the Machine's limitations due to the morality Finch gave the Machine. Putting the machine into the service of humanity by forcing it to preserve human life, while leaving Samaritan with control over them, as slave to no one and no ideals other than its own.
  • The various graphics from Samaritan's viewpoint reinforce the idea that it is more advanced and powerful than the Machine, seen in the comprehensive categorization of individuals, a more advanced pattern recognition (tracking the routes of people and traffic in Manhattan), as well as higher cognitive processing.
  • In contrast with the Machine's POV, which has a slight barrel distortion, Samaritan's point of view has pincushion distortion, which causes vertical lines to bow inward, toward the center of the image. This type of distortion most commonly occurs with the use of telephoto lenses.
  • It appears that Samaritan has halted the creation of another surveillance network, along with research into AI, in order to prevent the creation of more competing systems. (“Panopticon”) (“Nautilus”)
