Google has released reCAPTCHA, a free service to protect websites from spam and automated malware breaches.

reCAPTCHA uses a risk-analysis engine and adaptive CAPTCHAs to recognize when a human user or a bot is attempting to access a site, and it learns as CAPTCHAs are solved to digitize text, annotate images and build machine-learning datasets. reCAPTCHA adapts to provide easy CAPTCHAs for humans and progressively more difficult ones for bots.

Information on how developers can implement reCAPTCHA on their sites is available here.

Sony Pictures computer systems hacked

“We Want equality [sic]. Sony doesn’t. It’s an upward battle,” the hackers wrote in an e-mail to The Verge.

“Sony doesn’t lock their doors, physically, so we worked with other staff with similar interests to get in,” the hackers wrote to The Verge. “Im sorry I can’t say more, safety for our team is important [sic].”
