New Delhi, March 24: The government has asked telecom companies to make possible within 15 days, monitoring of content transmitted through Blackberry or stop the service that is already under official scanner for security lapses.

The directive has been issued to the respective service providers to work out with officials of Blackberry licensor Research in Motion (RIM) of Canada to provide fool-proof security system in the country, senior officials in the Department of Telecom (DoT) said.

If the services are stopped, over four lakh users of Blackberry would not be able to access this premium service which enables users to send and receive e-mail in the form of SMS.

The DoT Secretary had recently said that the government was keen to resolve the matter at the earliest.

When contacted a spokesperson of RIM, licensor of Blackberry services, said that RIM operates in more than 130 countries around the world and respects the regulatory requirements of governments. RIM does not comment on confidential regulatory matters or speculation on such matters in any given country.

Telecom Minister A Raja had also said that security of the nation was of paramount concern and this would not be sacrificed at any cost.

C-DoT, a technical wing of DoT, has the monitoring capabilities provided the licensor puts the server in India enabling interception of contents of e-mails, if required, on the Blackberry handsets.
