Traditional Turing tests
permit counterfeiting and require matching only a narrowly defined level of human performance.
The scientists then compared the outputs from both humans and machines through 'visual Turing tests
In fact, Michael Casey, a professor of music and computer science at Dartmouth College, plans to hold several Turing tests
early next year, perhaps followed by some Lovelace tests.
GOTCHA (Generating panOptic Turing Tests
to Tell Computers and Humans Apart) would be suitable for protecting high-value accounts, such as bank accounts, medical records and other sensitive information.
Nor have annual Turing tests
, conducted under the auspices of the Loebner Prize, crowned a computer victor.
A general solution of "reverse Turing tests
" was introduced by Moni Naor  and later popularized as "Completely Automated Public Turing test
to tell Computers and Humans Apart" (CAPTCHA) (Moni, 2008, Ahn et al, 2003).
Deliver on that promise and meet the e-reader Turing tests
, and I'll place my order.
Machines that pass Turing Tests
operate with sets of rules so they can appear human--one machine even was programmed to make typing "mistakes" in order to appear more human.
The whole process, in short, is very much an ongoing series of natural, concrete Turing tests
Completely automated public Turing tests
to tell computers and humans apart (CAPTCHAs) are implemented on many Web sites to verify that the user is human, as opposed to an automated program.
New features on this version of Spam Sleuth include E-mail Stamps, which charge companies a fee to send spam, and Turing Tests
, which force suspected spammers to answer questions in order for their e-mails to be delivered.
He thinks that the Turing Test
won't be decided in a single big event; instead, "miniature Turing Tests
are happening all the time, every day, whenever a person puts up with stupid computer software.
