Why Google and Apple Don't Want to Give Law Enforcement the Master Key to Your Data

Technology giants send a message about encryption to President Obama.

"We urge you to reject any proposal that U.S. companies deliberately weaken the security of their products. We request that the White House instead focus on developing policies that will promote rather than undermine the wide adoption of strong encryption technology," the letter said.

By giving the government the master key to decode encrypted data, the signatories said it could leave billions of people vulnerable to cyber criminals and deal a detrimental blow to information security.

The signatories of the letter asked Obama to reject any proposals to insert a back door into their operating systems and threw their support behind a December 2013 report from the President's Review Group on Intelligence and Communications Technologies calling for an increase in the use of encryption.

By protecting data, they said "such policies will in turn help to promote and protect cybersecurity, economic growth, and human rights, both here and abroad."
