EFF made an announcement that both Apple and Dropbox have indeed joined the Digital Due Process coalition, this aims to press congress to update the Electronic Communications Privacy Act.
This act was passed by the congress in 1986, when mobile phones were still very rare. However, this law is still the primary law governing how and when law enforcement can access personal information and private communications stored by providers. The DDP now wants to ensure that the government can not access your personal information without taking it to court first to obtain a warrant. This information will include your emails, photos, documents, backup and your mobile phone.
It is noted that the current ECPA is not clear on if these documents are now protected from intrusion. There are also other important coalition members that include Amazon, Intel, AT&T, Google.
