NEW DELHI: UC Web, the browser owned by Chinese internet giant Alibaba , has come under the scrutiny of the government as part of investigations against Chinese companies over data theft. If found guilty of stealing data of Indian users, the company may be banned in the country, a top official in the Ministry of Electronics and Information Technology said."Complaints have been received against UC Browser that it sends mobile data of Indian users to servers in China. The matter is being looked into,” the official said.UC Browser claimed to have over 100 million monthly active users in India as per a report last year while globally, its user base is nearly 420 million.When contacted on the matter by TOI, a spokesperson for the company said that it takes security and privacy very seriously, though adding that “it is common practice for IT companies to place servers all around the globe to provide better service to its users... We will not do anything to breach the trust of our users.”“At UC Web, we take security and privacy very seriously and work hard to comply with local regulations of each region we operate in… We have strong measures in place to encrypt the data while we transmit it,” the spokesperson said, adding that the company is yet to any notice or intimation from the government on the matter.The spokesperson, however, defended the decision to collect user data: “It is also standard industry practice to collect user information and data in necessary scenarios to provide users with localised services. We take necessary authorization from users to collect this data.
