"Over the last few days there has been a constant scrutiny over Face book having access to your SMS. Buried within the latest update for Face book’s Android app is a feature that is causing growing concern among some users," Kaspersky said in a statement on Monday. (Agencies)

Face book is one of the companies that have been accused by US Whistleblower Edward Snowden of sneaking in to private information to help National Security Agency of US in spying at global level. The social media firm has denied that allegation.
The Face book application at the time of installation on Android mobile phones seeks certain permissions and the updated version now asks users to allow it "Read your text messages (SMS or MMS)".
The social media's logic behind seeking access to SMS is that "if you add a phone number to your account, this allows us to confirm your phone number automatically by finding the confirmation code that we send via text message".
The updated Facebook application now wants to "Read calendar events plus confidential information" which it justifies as it is required to allow "the app to show your calendar availability (based on your phone’s calendar) when you’re viewing an event on Facebook".
Facebook sends code via SMS that has to be entered when a user registers with the social media website which in a way helps the company verify the authenticity of users twice.
"Two-factor authentication provides an extra level of security, so it's good to see Face book providing this option ... As a final note, we'd urge people to carefully check the permissions requested by any app when you first install it," Kaspersky Lab's Principal Security Researcher David Emm said.
Kaspersky added the permissions also grants access to multimedia messages, for which reason is not explicitly given.
It expressed apprehension on the word 'automatic' used in the permission sought by Facebook.
"...the key, it seems to lie in the word 'automatically'. Surely the app doesn't need to do this automatically. Face book could simply prompt me to type in the code manually. Or, at the very least, provide this option," Kaspersky said.
It added that this may be an innocent feature "but in the light of growing concerns about online privacy, such an option would help to allay people's fears".
Face book is reported to have 93 million users in India out of which 75 million access it from their mobile phone as of December 2013.
