Smartphone Surveillance Meaning |
Definition of Cellphone Surveillance by
DigitalBank Vault Encryption.

Many times, a person suspected of something illegal by the authorities is placed under surveillance, meaning he or she is closely watched to see if their suspicions are well-founded.

Surveillance is the monitoring of behavior, activities, or information for the purpose of influencing, managing, or directing. ... Surveillance is used by governments for intelligence gathering, prevention of crime, the protection of a process, person, group or object, or the investigation of crime.

Phone surveillance is the act of performing surveillance on phone conversations, location tracking, and data monitoring of a phone. Before the era of mobile phones, these used to refer to the tapping of phone lines via a method called wiretapping. Wiretapping has now been replaced by software that monitors the cell phones of users.While mobile phone surveillance has been carried out by large organizations for a long time, especially for clues of illegal activities, more and more such surveillance is now carried out by individuals for personal reasons.

For example, a parent may become a "text spy" in order to monitor a child's texting activity. This brings in the moral, ethical, and legal question of who owns people's privacy.Cellphone surveillance (also known as cellphone spying) may involve the tracking, bugging, monitoring, eavesdropping, and recording of conversations and text messages on mobile phones. It also encompasses the monitoring of people's movements, which can be tracked using mobile phone signals when phones are turned on.

Mass cellphone surveillance

StingRay devices are a technology that mimics a cellphone tower, causing nearby cellphones to connect and pass data through them instead of legitimate towers. This is invisible to the end-user and allows the operator of the device full access to any communicated data.
This is a form of Man-in-the-middle attack.

StingRays are used by law enforcement agencies to track people's movements, and intercept and record conversations, names, phone numbers and text messages from mobile phones. Their use entails the monitoring and collection of data from all mobile phones within a target area.

Law enforcement agencies in Northern California that have purchased StingRay devices include the Oakland Police Department, San Francisco Police Department, Sacramento County Sheriff's Department, San Jose Police Department, and the Fremont Police Department.

The Fremont Police Department's use of a StingRay device is in a partnership with the Oakland Police Department and the Alameda County District Attorney's Office.End-to-end encryption such as Signal Messenger protects traffic against stingray devices via cryptographic strategies.

Tower dumps

A tower dump is the sharing of identifying information by a cell tower operator, which can be used to identify where a given individual was at a certain time. As mobile phone users move, their devices will connect to nearby cell towers in order to maintain a strong signal even while the phone is not actively in use. These towers record identifying information about cellphones connected to them which then can be used to track individuals.In most of the United States, police can get many kinds of cellphone data without obtaining a warrant.

Law-enforcement records show police can use initial data from a tower dump to ask for another court order for more information, including addresses, billing records, and logs of calls, texts, and locations.Cellphone bugs can be created by disabling the ringing feature on a mobile phone, allowing a caller to call a phone to access its microphone and listening.

One example of this was the group FaceTime bug.

In the United States, the FBI has used
"roving bugs", which entails the activation of microphones on mobile phones to enable the monitoring of conversations.

Cellphone spying software is a type of cellphone bugging, tracking, and monitoring software that is surreptitiously installed on mobile phones.

This software can enable conversations to be heard and recorded from phones upon which it is installed. Cellphone spying software can be downloaded onto cellphones. Cellphone spying software enables the monitoring or stalking of a target cellphone
from a remote location with some of
the following techniques:

Allowing remote observation of the target cellphone position in real-time on a map

Remotely enabling microphones to capture and forward conversations. Microphones can be activated during a call or when the phone is on standby for capturing conversations near the cellphone.
Receiving remote alerts and/or text messages each time somebody dials a number on the cellphone

Remotely reading text messages and call logs

Cellphone spying software can enable microphones on mobile phones when phones are not being used and can be installed by mobile providers.


Intentionally hiding a cell phone in a location is a bugging technique. Some hidden cellphone bugs rely on Wifi hotspots, rather than cellular data, where the tracker rootkit software periodically "wakes up" and signs into a public wifi hotspot to upload tracker data onto a public internet server.

Lawful interception

Governments may sometimes legally monitor mobile phone communications - a procedure known as lawful interception.In the United States the government pays phone companies directly to record and collect cellular communications from specified individuals.US Law enforcement agencies can also legally track the movements of people from their mobile phone signals upon obtaining a court order to do so.Real-time location dataIn 2018, United States cellphone carriers, AT&T, Verizon, T-Mobile, and Sprint, that sell customers' real-time location data publicly stated that they would cease those data sales because the FCC found that the companies had been negligent in protecting the personal privacy of its customers' data.

Location aggregators use that information as well as bounty hunters and others including law enforcement agencies some of which had not obtained search warrants. FCC Chairman Ajit Pai concluded that carriers apparently had violated federal law. However, during 2019, the carriers were continuing to sell real-time location data.
During late February 2020, the FCC was seeking fines on the carriers in the case.
