Google and other data sources, such as cell phone towers and license plate readers, offer lists of devices, vehicles, and suspects around a specific location and time period.
Known as geofencing, data for a specific geographical area and time period may be retrieved for analysis. This is particularly helpful for law enforcement when people commit crimes while carrying a cellphone that can be used as a tracking device.
View the information in a link chart, timeline, and map to see all the activity associated with an event. You and your team can combine data from multiple sources and manually add the evidence you collect. Perform analysis to find hidden relationships among your people, devices, places, and events.
Make this a Saved Visualizer to capture all your evidence for one incident.
Some judges are ruling that search warrants for Google's geofencing data are too broad and violate the Fourth Amendment for unreasonable search since most of the data includes activity by innocents. No one disputes that almost all of the Google geofence data or cellphones connected to a cell tower near a crime scene are owned by innocent people.
Sentinel Visualizer can address such concerns by serving as an intermediary between the court's desire to protect privacy while addressing the needs of law enforcement and public safety.
When used by non-law enforcement personnel under strict guidance, Sentinel Visualizer can manage the large amounts of data, keep the data of innocent parties private, and only share the high value suspects with law enforcement personnel. That's all that needs to be given to the investigators and helps them by removing most of the noise. This is particularly possible when multiple events separated by location and time exist to identify common entities and eliminate bystanders.
Each saved Visualizer for an incident may contain thousands of entities (devices, people, license plates, RFID tags, etc.). Sentinel Visualizer performs Multi-Visualizer Analysis to quickly identify entities that appear across them.
Compared to the raw data, this is usually a tiny list of suspects that is highly actionable intelligence. Cell phones or license plates at multiple crime scenes that are separated by time and geography are very suspicious. These are high priority targets to invest your limited budget and time for deeper investigations. It should also satisfy the privacy concerns raised by the courts while improving your efficiency.
For instance, by selecting five saved Visualizers of similar arsons or assaults in different locations/times, Sentinel Visualizer's multi-Visualizer analysis quickly generates the list of entities that appeared in all or several of them.
