With the security agencies already putting to test BlackBerry's messenger service, its maker Research In Motion (RIM) has been asked by India to provide technical solution to intercept its enterprise mailing service which provides a private virtual networking among a group of people.

The BlackBerry has provided with a technological facility of intercepting its Messenger service between two handsets after providing the Personal Index Number (PIN), official sources said.

The security agencies were ascertaining the intercepting provisions provided by the Canadian smart phone manufacturer for intercepting BlackBerry Messenger (BBM) for which a detailed report would be submitted to the Ministry of Home Affairs later.

The sources said that while some delay had been noticed in the getting the intercepts, the BlackBerry manufacturers had assured them of getting a real time intercepts with very less human interface once the cloud computing environment was put in place.

The Department of Telecom and the security agencies are now looking forward for a technical solution to be provided by the smart phone maker for intercepting the BlackBerry Enterprise Service under which a private virtual network is created within the server between a group of individuals who can exchange emails without getting intercepted, they said.

The DoT, in consultation with the Home Ministry officials, are now pressing for providing the access to BlackBerry Enterprise service (BES).

The DoT had asked other service providers including Google, Skype and Virtual Private Network (VPN) also to work a solution of intercepting their services within the stipulated 60 days as provided to the BlackBerry makers.

These service providers have been issued notices earlier and all of them were asked to comply with the directive or else they will have to close down their networks in India, the sources said.

"There will be no discrimination. All networks operating in India will have to give access to their services to law enforcement agencies," a senior Home Ministry official said.

Nokia, which wanted to introduce push-mail service in India, has already agreed to set up a server in India.

The Union Home Ministry has discussed the security concerns related to voice and messaging services on the Internet offered by Google and Skype in India, both of which have considerable presence in the country.

The data travelling through Google, Skype, VPN and a few other networks is not accessible by security agencies in the country. Even the terrorists who carried out the audacious 26/11 attack in Mumbai, used Skype services.

Google is a popular search engine which also offers email, online chatting and owns social networking website Orkut.

Luxembourg-based Skype SA provides telephony services over the Internet on personal computers and mobile phones also uses proprietary encryption and decryption.

VPN is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organisation's network.
