To clarify the Smartphone camera pin



Last-modified to reveal the microphone of the camera or on a Smartphone, Smartphone pin-the user can reveal with a camera and microphone, researchers have warned. Called from pin skimmer Cambridge University team found that identifies the code you typed in as many soft keypad you can use the program. Via software, camera watches your face, and then typing and listening to click through a microphone.

Test of the Google nexus S and Galaxy S3 on a Smartphone. "We have malicious and demonstrated you can normally used for meetings and face recognition camera' says report author Professor Ross Anderson and Laurent Simon. According to the survey, is used to detect touch events on the input PIN user Mike is. Click on 'listen' can actually be it mobile phone users virtual numbers by pressing.


Camera after the user is doing this, and ', depending on the position of the numbers correlate to users tap ', calculates the orientation of the phone. "We pull lightly on your phone look or appear to move by entering your face ', said Professor Ross Anderson security engineering at Cambridge University.


It worked, just how much our surprise he told the BBC. When trying to work out the 4-digit Pin, hours after 5 attempts successful programs 50% or more. After the trial was 10 of the 8-digit PIN and success rate 60%. For many smartphone users to lock my phone pin increasingly used to access other types of applications on a Smartphone, such as banking. It says report author when entering PIN someone still doubts that resources must be accessible by phone is a sensitive.

Randomize the key.

"For example, may need to the user when the call comes in to; While unlocking his cell phone ring tones to hear otherwise he may assume the caller hung up." One proposal uses long number PIN will be identified to prevent, warn researchers this memorability and ease of use affected. "" Suggested randomized keypad numbers, researcher's believe this crock phone easier to use ".


Get rid of the password in fingerprint and face recognition, offers as a more drastic solution. "Note that if you develop payment applications that exists these risks you' warns Professor Anderson.

Microsoft seeks to turn your smartphone into a mood ring



Your smartphone is already an extension of your body. It knows you — it understands you, right? But what if it knew how you were really feeling? Microsoft Research has built a prototype system that aims to detect the user’s mood. If the research pans out, phones in the future could add mood detection to the array of accelerometers, gyroscopes, and GPS chips that already customize the experience — emoticons could go the way of the dinosaurs.


Rather than go with a mood ring analog and develop some borderline pseudo-scientific physical sensor, Microsoft Research created a software package called MoodScope. This is a lightweight application that runs on a smartphone and uses context clues to infer how the user is feeling.


MoodScope measures a huge array of interactions with the phone including app usage, phone calls, emails, text messages, browsing history, and geographic location. This works out to thousands of data points each day. The team recruited 32 study participants and had them use the system for two months. During that time, they also completed self-assessments of their mood to see how close the software was getting to the truth.


The results of the preliminary study were shockingly (and maybe disconcertingly) accurate. Without any personal tuning, the app was able to guess at someone’s mood with 66% accuracy. That means anyone picking up the phone would see that level of exactness. When the software was “calibrated” for an individual user, the accuracy jumped as high as 93%.


MoodScope uses a two-axis scale to measure mood. On the X-axis is pleasure, and activeness is on the Y. This is an oversimplification of emotional states, but it can encompass general feelings like happiness, calm, and boredom. That’s probably all the detail you need to enhance a mobile experience, Microsoft says.


It is believed this technology could be used to improve interaction and recommendation online. A social network could automatically include your predicted mood, or a recommendation engine like Netflix could more accurately tailor itself to your state of mind at the time. If MoodScope proves to be a success, you might never again have to wonder if that text message you received was supposed to be sarcastic or serious.


The prototype build of MoodScope was developed for iOS and Android devices. Despite gathering and analyzing all that data, it only used a smidge of battery in the study — just 3.4 milliwatt-hours per day. That works out to 20 minutes of standby time on the average smartphone. It might be even less draining in practice as some devices running Android gather similar data for Google Now search. If MoodScope could plug into the vast stores of data Google already has, it might be even more effective. There are obvious privacy implications here, but we’ve adapted to worse.


MoodScope won’t be able to detect sudden swings in mood, or external factors that might cause stress. However, it may make your smartphone feel a little more personal. Work is continuing on the app in hopes it will be a real product someday.
