Cayla is an internet connected doll developed to communicate with children through speech recognition. Hailed as an interactive play-time friend for young children there are now fresh worries over safety and suitability, after it was revealed she can be hacked, to say whatever the hacker wants.

The concern is that she could be vocalising or teaching young children inappropriate words or phrases. The company that manufactures Cayla has insisted that it has installed technology to protect against this and that parents can ban words or topics from Cayla's vocabulary using her app.

However this story highlights the ongoing discussion on privacy and internet safety. Samsung was forced to issue a warning yesterday to its smart TV customers not to discuss personal information in front of their sets as there is a risk of privacy invasion. Could interactive internet driven gadgets like Cayla be a new method for hackers and fraudsters to steal information?
