FIGu RE 3.8.10 Applying and combining automated intelligence support.
3.8.8.2.1 Free Search
Free search tools reduce costs and save time by finding the significance in huge amounts of information
from e-mail, chat, instant messaging, Web sites, and transferred files. Advanced call data search can find
specific information such as a person’s name or a specific telephone number. Sophisticated text search by
call content allows service providers and LEAs to search all locations and all forms of information with
just a keyword, phrase, or synonym. Fuzzy searches are used to improve the effectiveness of the search
activities. Reports of all call details can also enlighten investigators with important information.

3.8.8.2.2 Visual Analysis
Another category of tools that help service providers and LEAs uncover instances and relationships is
visual analysis. These tools help to put all the intercepted data into graphic presentations, pictures, and
charts to identify otherwise hidden patterns and relationships.
3.8.8.2.3 Location Tracking
Knowing the criminal’s location as the call is being intercepted can be as important as the call itself.
Location tracking solutions, for example those from Verint with its RELIANT product, provide a graphic
positioning of the target using a cell phone, drawing the route and direction of the target directly onto
maps of the geographical area.

3.8.8.2.4 Voice Verification
Verifying the speaker’s identity in a conversation can be accomplished with a voice verification function.
A voice bank stores voice samples so the user can compare the intercepted caller’s voice to the samples.
This helps ensure accuracy of evidence as well as enhancing the effectiveness of the investigation.

3.8.8.2.5 Court Evidence
Successful prosecutions require comprehensive collection and strict adherence to the rules of evidence
handling. Intelligent analysis tools provide law enforcement and prosecutors with the basis to develop
and manage intercepted communications throughout the process from collection to prosecution.
