US president Barack Obama has issued a fresh warning against encryption calling the data on electronic devices really dangerous. Speaking in Austin on Friday, Obama called on tech companies to build a safe encryption key to assist in law enforcement investigations. He warned that a failure could see stringent measures by Congress. The president urged encryption advocates to avoid taking an absolutist stance. The debate pitting encryption and personal privacy has intensified in the US in recent years. That after whistleblower Edward Snowden revealed the metadata collection program by the National Security Agency. The issues have recently brought the Obama administration on a collision course with Apple. The world's largest tech firm has challenged a federal court order to help the FBI break into an encrypted iPhone used by a San Bernardino terror suspect.
