Analysis of Telephone Call Data Records with Sentinel Visualizer

Discover more about Telephone Call Data Records Analysis


What valuable information can you get out of huge amounts of telephone call records?

The US government is trying to collect all the telephone call data records (CDR) for US and international phone calls though its PRISM program. Does having this information constitute snooping? Is it an invasion of privacy? Or can it really help investigators track, find, and thwart threats?

Does it Matter with So Much Data?

With billions of phone calls, how could anyone possibly find anything of value amid all the innocent, unrelated calls? No one can possibly gain significant insight looking at an Excel spreadsheet or a database showing rows and columns of all those calls. Isn’t it just noise?

How Sentinel Visualizer Analyzes Call Data Records

Without advanced analytics software, the data is overwhelming. Our commercial¬†Sentinel Visualizer program from our Advanced Systems Group provides a platform to gain insight into the massive number of phone calls. It’s about managing large amounts of data, seeing the relationships between entities (phone numbers and people), drilling down where necessary, and filtering based on time, geography, and relationships:

  • Call detail records are imported into the Sentinel Visualizer database (SQL Server)
  • Link Analysis Networks can be used to visually see the calls made by any phone number
  • Multiple levels of phone calls can be linked to identify groups of phones related to each other (cells of activity)
  • Geospatial Mapping and integration with Google Earth to see calls across the world
  • Social Network Analysis (SNA) to identify related phones (cells) and spanners between cells
  • Temporal Analysis can be used to filter data to specific time ranges
  • If information exists for known individuals and their phone number(s), related phones can be quickly identified as warranting additional investigation
  • Link Traversal Analysis can be performed between two phone numbers to show all the phones related to them through multiple levels, and quickly filter out the unrelated calls to identify the “community of interest”
  • Numerous reporting and exporting options: print diagrams and customized reports, or export them in image, PDF, Word, Excel.

Boston Marathon Bombing and the Use of Social Network Analysis (SNA) Software

Sentinel VisualizerWhile we at FMS are best known for our Microsoft Access add-in products, we are also a leader in the Big Data analytics world with our Sentinel Visualizer product from our FMS Advanced Systems Group.

Sentinel Visualzer helps analysts mine their data to find hidden relationships among people, places and events. Built with Visual Studio .NET on a SQL Server database, Sentinel Visualizer provdes advanced data visualization through link analysis, geospatial mapping, timelines, social network analysis (SNA), advanced filtering and decluttering, and many other tools to maximize the value of data.

MIT Technology Review Article on Social Network Analysis and Boston Marathon BombingAs the rampage and manhunt in Boston, Cambridge, and Watertown transpired, MIT Technology Review published an article that mentioned our Sentinel Visualizer product. In the April 19, 2013 article, David Talbot describes the rise of technology to detect the activities of criminals over the Internet and connect seemingly unrelated people, places and things.

Sentinel Visualizer Helping to Expose Human Rights Violations

Our link analysis program, Sentinel Visualizer, continues to help organizations better manage and understand their data for some amazing missions.

Read our joint press release with London based Videre Est Credere (Seeing is Believing) on how Sentinel Visualizer is a cornerstone of their methodology for organizing their data and activities. They train and equip citizens in Africa to record human rights atrocities and expose it to the global press. We're proud to play a role in their efforts to make a more safe and just world, and thank those who are willing to do so at great personal risk.

New Video: An Introduction to Social Network Analysis

Link Analysis, Social Network Analysis, Geospatial, and Timeline SoftwareThe FMS Advanced Systems Group has a new video for its Sentinel Visualizer program: An Introduction to Social Network Analysis (SNA). If you are trying to find hidden relationships among people, places, and events, Social Network Analysis can help.

Social Network Analysis is a subset of network theory that finds important relationships and centrality in complex networks. Learn how organizations in the law enforcement, intelligence, defense, finance, and other data intensive fields are using Sentinel Visualizer in their missions.

Here's more information on Sentinel Visualizer and its Link Analysis features.

Use Link Analysis to Visualize Your Data

Link AnalysisWe are all used to seeing the 'rows and columns' metaphor when looking at data. In fact it is the primary interface for many of our data analysis tasks.

But rows and columns can hide valuable patterns. What happens when you take data out of a database and visualize it as a network? Now you can see important connections, centrality, trends, movement over time, and many other key indicators.

Check out our article on Link Analysis and Social Network Analysis to see how our Sentinel Visualizer solution provides innovative ways to get more meaning from your data.
