Use of Encryption Foiled the Cops a Record 9 Times In 2013 115

realized (2472730) writes "In nine cases in 2013, state police were unable to break the encryption used by criminal suspects they were investigating, according to an annual report on law enforcement eavesdropping released by the U.S. court system on Wednesday. That's more than twice as many cases as in 2012, when police said that they'd been stymied by crypto in four cases—and that was the first year they'd ever reported encryption preventing them from successfully surveilling a criminal suspect. Before then, the number stood at zero."

    There are obviously thousands of people using encryption because they have a legitimate reason to hide something, and criminals also have something to hide, so it stands to reason that they'd also use encryption.

    So why aren't there more cases of encryption impeding an investigation? Possibilities:

    1) Only stupid people (who don't use encryption) are caught - yeah, not with numbers /that/ low;

    2) The numbers are being deliberately under-reported;

    3) A lot of encryption is breakable or has backdoors;

    4) Most people under investigation have software planted on computers or hardware keyloggers.

    Bollocks. The only difference between today and the past is that you can easily see an encrypted file, you can know it's encrypted, surmise it's probably got something juicy, and just be unable to break in.

    It has the exact same effect as a lot of low tech stuff. For instance, memorizing a secret note than burning it would also leave no trail for law enforcement to follow. As would a secret conversation a thousand years ago you can't overhear because there was no listening devices around back then.

    Therefore, I would suggest that actually finding encrypted files law enforcement cannot break into is actually an improvement.
