How secure is the Picture Password option?

Can any of the developers associated with the Picture Password provide some math?
A simple four digit numeric pin for example provides 10,000 combinations.
From simple playing around, it looks like the Picture Password requries a number alignment in a 25x25 grid or thereabouts which is about 525 positions, times 10 digits or about 5250 combinations, except that the ordering of the digits seems to change with each attempt.
Then there is also the maximum number of attempts (10) but it requires manual typing after 5. It would be good to have an understanding of the probabilities involved. I guess ultimately, does the picture password provide an equivalent of a 3-1/2 digit numeric pin or does it actually provide much better protection than that?
Thanks,
Bob.

Interesting question, it will obviously change slightly depending on the device you are using as they have different screen sizes but I'm also curious to know.

  • IPhone Security: How secure is the iPhone?

    We just purchased iPhones for our family. However, I have a question regarding cyber security on these devices.
    Specifically, we have the phones set up to access our MobileMe accounts, and thus the MobileMe password is part of our iPhones. This leads to two questions:
    1) If someone acquires our phones, can they easily reverse engineer the phone to determine our MobileMe passwords?
    2) When we use various free wireless services (for example, while travelling at airports), how secure is the password data as it is passed from our iPhones to MobileMe over the RF spectrum? Could someone easily “listen in” to the communication and sniff out the passwords?
    It’s not that crucial now since it is just our MobileMe account, but I would like to use my iPhone for work e-mail and am not sure if this is safe or not.
    In addition to these questions, any advice, comments, or other sources on iPhone security would be greatly appreciated.
    Thank you very much for sharing your expertise!!!

    It depends on what the website does, and the rules are the same as using a wifi laptop:
    A) If a site uses regular HTTP with no encryption, any text data can be intercepted.
    B) Using HTTPS encryption like banks do, data can be sniffed but cannot be read unless a sophisticated hacker can unencrypt the sniffed data.
    C) Using a secure VPN for your iPhone (like HotSpot Shield), you can encrypt traffic between the iPhone and the VPN service so that all your communications are secured regardless of what the website does.
    I don't have a MobileMe account, so I don't know whether they layer any encryption over the login, but if they're like many sites, they probably do. As for what happens after login, this article is not very encouraging if the info is still current. That is why I use a VPN.

  • UCM - WEBDAV - How to Disable the New Folder option in the action popup

    I am trying to implement WebDav functionality. I don't want the users to create folders in the folder mapped to a security group. As long as the user has privilege to contribute to the security group he/she can checkin documents but they should not be able to create folder under it. I did not find documentation as to how to disable the new folder option in the context action menu that pops up on mouse right click. Is there any way we can do that?
    Thanx.

    This is the boilerplate text often used in connection to networks in general. It is impossible to troubleshoot someone else's network remotely, and that's why it's not supported by Adobe:
    If you are opening files over a network or saving them to a network server, please cease and desist immediately in the event you are currently experiencing problems with one or more files.
    Working across a network in general is not supported by Adobe.
    See: 
    http://kb2.adobe.com/cps/406/kb406793.html
      Copy the CLOSED file from your server to your local hard disk, work on it, save it again to your local hard disk, close it, and copy the closed file back to the server.
        Of course, the fact that Adobe does not support working across a network does not necessarily mean it won't work.  It should.
        Adobe's position is that there are too many variables in a network environment for them to guarantee that everything will work correctly in every network, especially given the fact that if something does not work properly, it's probably the network's fault, and Adobe has no way of troubleshooting your network.
      If you can't work locally, you are on your own, and if something happens, you're on your own. If you must work from a server, make sure your network administrator is a competent professional.

  • How to change the picture frame size in Lightroom 5 Book

    I would like to control the actual picture frame size when making a Book in Lightroom 5. Or else know the sizes of the different picture frames provided by choosing the different page layouts. That way I can either change the picture frame dimensions to accomodate each photo or change the image size to fit in the offered picture frame. I find that using the software as is winds up cropping the images in unwanted ways. Modifying the picture frame would be my preferred alternative. Appreciate any ideas

    Hi again Tony,
                I have been using Adobe Photoshop 7, Photoshop Elements, Perfect Photo Suite, Photo Studio, etc., changing Image size, placing a picture on a page and then, do a simple last minute size adjustment by using the arrows to stretch or shrink it in place. Things would be a lot simpler if I could do the same thing with the cells in Lightroom 5. Cell pad adjustments do not fill the bill.
    I think we’ve pretty much concluded this exchange. Thanks again for your effort.

    the fontpanel enlarged when you dbclick the title bar to enlarge the fontpanel to entire screen,but the other objects (for example,the button,the string,and so on)on the fontpanel not enlarged with the varity of the fontpanel, only keep the original size.To answer your first question:
    To change the size of only the Picture you can use the Draw Area Size like you already have. However if you want to move the other controls around the picture, you may need to use their Position Properties.
    On to question 2:
    All of the VIs you are discussing come with the NI-IMAQ driver and NI�s Vision package. To use those VIs you will need to have the IMAQ driver and have purchased our Vision software. Machine Vision and then you can click on the Machine Vision Software link to learn more about the package.

  • How to set the JVM Startup Options?

    Hi,
    I want to know how to set the JVM Startup Options...
    The idea is, I want to test how the remote clients can access an EJB that is running on a different machine... Remote client here means, I have a java client application that runs on one machine and that contacts an EJB thats running on a different machine... I posted this question in J2EE forum and I got this reply...
    If you need to access EJB components that are residing in a remote system other than the system where the application client is being developed, set the values for the Java Virtual Machine startup options:
    jvmarg value = "-Dorg.omg.CORBA.ORBInitialHost=${ORBhost}"
    jvmarg value = "-Dorg.omg.CORBA.ORBInitialPort=${ORBport}"
    Now how to set the JVM Startup Options? I know my server ORBHost Name and the ORBPort..
    Anybody to help !!!
    Thanks in advance,
    Karthik

    java -Dorg.omg.CORBA.ORBInitialHost=${ORBhost} -Dorg.omg.CORBA.ORBInitialPort=${ORBport} <the main class>
    That should do it..

    there was a way to see the website data and stored information, but not the passwords. they were ************
    you were only able to delete the login information, and unfortunately, since i have not used the device in so long, have forgotten the language.
    so you will have to dig a bit.
    it was a command that you would enter into the browser address bar.
    if it comes to me i will repost, but for now...check here.
