Germany bans internet-connected 'spying' doll Cayla

German regulators have banned an internet-connected doll called "My Friend Cayla" that can chat with children, warning Friday that it was a de facto "spying device".Parents were urged to disable the interactive toy by the Federal Network Agency which enforces bans on surveillance devices."Items that conceal cameras or microphones and that are capable of transmitting a signal, and therefore can transmit data without detection, compromise people's privacy," said the agency's head, Jochen Homann.
