Target Detection Identifiers

This is a leaked document came from Snowden also but what is TDI or rather say Target Identifiers?

A brief explanation was taken out from TrackingIntellignce website.

Location Data
With an IMSI Catcher, the information discovered can be used to learn about general demographic values, but with a Target Identifier, physical location and intelligence attributes are revealed. Specifically, the Target Identifier can implement IMSI survey results for real-time localization of suspected criminal or terrorist elements. Is the Target at home? Is the Target not at home? By conducting quick GSM Monitoring Surveys, a surveillance operator can determine if a suspected Terrorist is in an area by using the cellular detection feature of the Target Identifier.

Intercepting Disposable GSM Phone / SIM Cards
Once the surveillance operator has the Target IMSI identification, he can use that number within the Target Identifier processing engine to lock onto the mobile phone and intercept the call. But what happens if the Target is using a disposable GSM phone? With a regular IMSI Catcher, you would only be able to determine the current IMSI number yet with a Target Identifier; you could follow the GSM handset even if the person of interest is using a pre-paid SIM card with a disposable GSM phone.

The system would conduct multiple IMSI surveys for GSM network monitoring, with the results acquire the IMSI number based on duplication of the Target Identifier results. Because a Target may appear in multiple locations with the same phone, even if it is a disposable GSM phone, the the system still intercepts the IMSI identifier through its cellular detection and survey processes. The results of the IMSI being discovered are used to provide the surveillance operator with both location forensics and covert audio intercept.
