Concerns about privacy
The news comes as the LinkedIn applications are forced to update their cell phone after security researchers discovered a flaw privacy.
Skycure Security said that thephone app sends calendar data without the password to the server without user knowledge LinkedIn.
That information includes meeting notes, which often contain information such as phone numbers and key codes for conference calls.
LinkedIn said the application was “no longer send data fromyour calendar section of a memorandum of the meeting.”
The company also stressed that the calendar function is afeature option.
But researchers who discovered the flaw, said transmission data to the server LinkedIn performed without “a clear indication of the application to the user.”
In a statement published on the company blog, head of mobile products LinkedIn Jeff Redfern said more information was added to the application so users can get a clearer picture of the transmission and use of their information.
