Wearable cameras are much more of a common sight these days, thanks in no small part due to the success of GoPro and similar small cameras. With the likes of Google Glass on the way, wearable technology is likely to become more prevalent in the next few years.

While many concerns have already been raised about the privacy concerns related to these new technologies, a group of researchers at Israel's Hebrew University of Jerusalem have identified a potential unexpected consequence: one that suggests you might not be anonymous even when you are behind the camera. 

The research found that it is possible to identify the person wearing a camera by the individual's unique 'motion signature'.

The team had 34 different people wear GoPro cameras attached to baseball caps. Running the resulting footage through a dedicated algorithm, they were able to identify the camera operator approximately 88% of the time based on their movements alone.

According to New Scientist, these findings could have consequences such as making it easier to identify the individual police officers wearing cameras, or help authorities identify people capturing footage during protests.

Writing about their findings, the study's authors say "the implication of our work is that users’ head-worn egocentric videos give much information away. This information can be used benevolently (e.g. camera theft prevention, user analytics on video sharing websites) or maliciously. Care should therefore be taken when sharing such raw video."
