Washington: The FBI has succeeded in unlocking Syed Farook's iPhone, but the overall fight against encryption is set to continue for long.

The American Civil Liberties Union on Wednesday released an interactive map highlighting all the instances where Apple and Google have been forced by the US government to unlock a mobile device. The ACLU claimed that the All Writs Act since 2008 has been used by the government several times to force these companies to provide assistance in hacking the phones of the customers.

The ACLU tracked at least 76 confirmed cases in 22 states where an order was applied by the government under the All Writs Act. Apple has also identified 12 pending cases in its court documents, and the ACLU has found one additional case in Massachusetts.

"The FBI wants you to think that it will use the All Writs Act only in extraordinary cases to force tech companies to assist in the unlocking of phones. Turns out, these kinds of orders have actually become quite ordinary," wrote Eliza Sweren-Becker, an attorney for the ACLU.

Most orders are against Apple, but some are against Google, too. In six states - California, New Mexico, North Dakota, South Dakota, South Carolina, and Alabama - the government has applied for orders against both tech companies.
