Karnataka college dropout's software helps cops track criminal trail

CDR analysisSaleem Landur (above) started a small comapny in 2000 that is now creating software tools for CDR analysis used to track cell phone and call data. .

When Indian law enforcement agencies are hunting for criminals these days, it is the digital footprints invariably cell phone usage trails left by fleeing criminals that they pursue to get to their quarry.

This pursuit such as zeroing in on suspect mobile numbers from thousands in use around a crime scene was once a tough task that considerably slowed down investigators. It involved days of poring through mountains of data.

Now it is just a matter of a click of a button, thanks to the contribution of a 37-year-old Muslim college dropout from Belgaum who drove an autorickshaw by night to fund his computer education.

A small company Saleem Landur started in 2000 in a room with a computer he hired for Rs 1,500 is now at the forefront of creating software tools for what police call CDR analysis or call detail record analysis.

The NIA, CBI, police units in Karnataka, Gujarat, Bihar, West Bengal, Chhattisgarh and even police in Nigeria and Algeria now have software tools designed by Landur's Prosoft e-Solutions to help them track digital footprints of criminals.

Landur's firm has 25 employees, a branch in Madhya Pradesh, and is setting up a Bangalore development centre. Landur also collaborates with Nasscom's Data Security Council of India to train hundreds of law enforcement officials in the use of technology in investigations.

Prosoft's C5 CDR analyzer tool is in its 4.0 version and "processes terabytes of data, billions of records on low-end servers within seconds", Landur said.

It analyzes and integrates call data for cell phones including tower location data, and provides investigators with simple representations of patterns of communication including geographical location of a caller, their movement or even alerts when two suspects communicate.

The analyzer also interacts with social networking sites and can fetch data such as phone numbers and names.
