"The Bangalore police last year managed to solve 18 missing persons cases. All thanks to the nifty software at the cyberforensics lab attached to the Cybercrime police station in the city.According to Sanjay Vir Singh, Deputy Inspector General of Police, Economic Offenses, Corp of Detectives (COD), Bangalore, the lab has a set of 12 softwares including a “read-notify” solution that can tell the location/city from when a person accesses his or her e-mail account. “Even if the missing person does not write an email and just clicks into the account, we can track it,” he explained."
