(AP) - A rising backlash to revelations of widespread National Security Agency surveillance takes many forms:
_ Encryption programs for email, Internet browsers, texting, instant messaging and other communications that encode messages so they appear garbled to eavesdroppers.
_ Disruptive campaigns that insert words like "anthrax" or "Taliban" in various digital communications to degrade the effectiveness of surveillance programs that search for red-flag words.
_ Cryptoparties are social gatherings where hosts teach attendees, who bring digital devices, how to use encryption programs.
_ Petitions and rallies demanding Congress and the Obama administration to rein in government surveillance.
_ Political reforms aimed to add privacy protections and boost oversight of government surveillance practices.
