Cell Phones Learn to Recognize Their Owners' Faces 198

Posted by samzenpus from the smile-and-dial dept.
An anonymous reader writes "Oki Electric this week began marketing a technology that inexpensively adds face recognition to camera-equipped cell phones. Oki's 'Face Sensing Engine' middleware decodes facial images within 280 milliseconds on a 100 MHz ARM9 processor, and can restrict access to mobile devices by recognizing their owners. Its purpose is to safeguard sensitive personal data -- such as email addresses and phone numbers -- in the event of loss or theft of their devices. The technology works by locating and mapping key facial features -- such as eyes, eyebrows, and mouth -- and adapts to changing facial conditions such as winking and smiling, according to Oki."

    All of this security is great if you're a secret agent, but I am not employed by the CIA. If I were to loose my phone, I would hope the finder would use the information in there to try to return the phone. What happens when someone with good intentions finds my phone and can't return it because I presumed him/her to be a theif and "safe"guarded it with this new technology?

      Dude, what to you think will happen if you just turn your phone loose like that? Keep it on a leash and you won't have to worry about someone returning it. ;-)

      All in good fun. Now let me post something on-topic so I don't seem like a jerk. My last PDA had a feature that would show a certain screen when locked -- the idea being that if it was lost, your data was still behind a password, but you could put a message saying, "If you find this device, please contact John Doe at . . . " on the chance that the finder would have the good intentions you speak of and return it. Perhaps phones could have something similar? Of course, a similar solution in your case would simply to not turn this security feature on.

        Such functionality is actually common in my part of the mobile world (Symbian/UIQ), for example my Motorola A1000 does exactly what you describe and I'd suspect others do as well.

    It's easy to offhandedly say who cares about the phone numbers of my friends and family. But for a sales force, keeping their contacts' information secure is one very important aspect of the job. If it is possible to create this security without requiring large lagtimes (like entering a PIN) or fault-prone hardware (fingerprint scanners), security becomes easier and safer than before for the average user.

    I'd be anxious to see how well it works in the real world before trying it out, but if it is an inexpensive piece of middleware, I wouldn't be surprised if it started turning up on the high-end phones in Japan and Korea. I'd be surprised if they started showing up here in the U.S., but I'd be surprised if any sort of cutting-edge technology showed up for general consumption here.

        Although I'm sure that you'd be able to set that too. However, as others have noted in this thread, emergency calls can still be made from PIN-locked phones and phones without any service provider. It's a software setting, so it's probably up to the user how much or little access he wants to grant unauthorized users.

    I think they are treating the phone a little too much like a gun.

    It's not like it will be the end of the world if someone can access my personal phone information. I can control what I store on there; it's my own choice whether to put private things in a phone, and while the list of people I call is private, it's really not that big of a deal. And there are other ways of remotely restricting access.

Millions would get their new "face recognition" phone in the mail...Open it up, and it takes one look at you and scrolls across the screen "Oh..wow..um yeah, I think that I just wanna be friends... you're a really nice guy though." Nothing like being shut down by a Motorola, especially the one with the nice ass (charger base).

    GODDD, is this news? I wonder what they're doing for security.

    Even before following TFA's link, I recalled hearing or reading about this when I was in Japan from Dec 04 to Feb 05. So, for this response, I "googled" it, and though I left on 24 Feb, and these links I'm supplying are dated 28 Feb, the news is sourced from material in the making long before that.

    OMRON Announces 'OKAO Vision Face Recognition Sensor', World's First Face Recognition Biometric for Mobile Phones

    http://www.japancorp.net/Article.Asp?Art_ID=9494 [japancorp.net]

    Face-recognition security comes to mobile phones
    http://linuxdevices.com/news/NS7172421600.html [linuxdevices.com]

    As for the Omron URL, this is an excerpt:

    "To use the unit, the user simply takes his or her own photo. The 'OKAO Vision Face Recognition Sensor' will automatically detect the user and unlock the unit. The identification process takes less than a second from snapping the photograph. Further, their is no need to adjust the camera position when taking the photo. If the face is included in the photo, the sensor will detect the owner automatically."

    However, it says nothing to ally to allay fears that a thief could place before the camera a picture of the owner of a stolen camera. It might be possible that the camera may someday have strobes or some thermal sensors that try to detect heat from a human body temp range, but that could be fooled with a transparent "Mission: Impossible" mask of the Gerry Anderson type (I purposely ignored the recent MI stuff since I loath money-grabbing remakes or remakes-in-title).

    I suppose a good security feature set would include:

    1. thumb or finger sensor with thumb print/fingerprint biometrics
    2. retinal scan (with enhancements to determine live/dead eyeballs
    3. breath, saliva or mucous tissue sample scan and later match/compare
    4. electrolytic sample (to determine voltage of live/dead person)

    If they can do that (put a mini-lab in the phone) then probably only CIA, NSA, MI6 and Japan's pending MI6, Mossad, and others would surely buy up these phones, or any other devices so equipped/secured.
