NEW DELHI: Swadeshi activist K N Govindacharya, whose PIL for live streaming of court proceedings is pending apex court's consideration, has moved the Supreme Court saying the video-conferencing software being used by the SC, High Courts and government departments are unsafe and pose a security threat to the nation.In a fresh plea, Govindacharya said that the video-conferencing platforms - Vidyo, Skype, Zoom WhatsApp etc - are all owned by foreign companies which have a user policy that allows them to transport data outside India and commercially exploit it. Govindacharya's counsel Virag Gupta said, "the judiciary and government departments must use only NIC-based or NIC-audited infrastructure for communication and video-conferencing for judiciary and other government officials."The petitioner said, "Transfer of data, especially governmental and judicial data outside India impacts national security and contravenes the Public Records Act, 1993, the Official Secrets Act, 1923, the Email Policy as well as Policy for usage of IT Resources of the Government of India. Transfer of data, which inevitably takes place as a result of use of foreign based video conferencing software, might assist, directly or indirectly, an enemy or might prejudicially affect the sovereignty and integrity of India, the security of the State or friendly relations with foreign States."Criticising the defence minister for using Zoom video-conferencing software to talk to the chief of defence staff, photographs of which were posted in the official twitter handle, Govindacharya said this assumes significance in the light of April 12 advisory issued by ministry of affairs' cyber coordination committee terming the video-application Zoom as unsafe.
