    security application using python

    Hi all, i'm new here to this forum and i would like to ask for some advice.

    i'm currently still a polytechnic student and my final year projet (FYP) requires my group to develop a security application for mobile phones

    so, my group has decided to come up with a data wiper application for mobile phones. so, i just want to check are there anything that we need to look out for or how do we start?all of us do not have any history of using python at all.

    Hi and welcome to the forum !

    Please let us know more about your concept of data wiper, so that we could guide you. What is this application required to do?

    oh sure, here's what the data wiper should be capable of doing

    the application will be able to clear any recorded data, such as contacts and messages, from the phone.

    i know there is a need for something called a symbian signed certificate in order to access to the phone. i'm not sure what else is needed to do.

    Hi,

    Yes, you could do it using Python for S60. I recommend you to get started with the Forum Nokia Wiki which will offer you good assistance in the course of your development.

    Its not Symbian Signed certificate Its a developer certificate that is issued by www.symbiansigned.com that is required to sign your applications or the pythonscript shell to get access to more capabilities from your application. Moreover you can also get it signed by using OpenSigned Online at the same site.

    However as you are a beginer you need not worry about those issues. Moreover the signing is only on 3rd Edition devices. You could use a 2nd Edition device for a start to get rid of all the so called complications of signing (or use an Emulator).

    You could get started using this article about Installing Pys60

    You can post your queries and problems here on the Discussion Boards (DiBos) and we will try to answer them.

    All the Best!

    Happy Pythoning

    Of course, the clearing can already be done by the phone user by "dialing" *#7370# and the memory card or mass memory can be cleared by using the memory card format feature of the built-in "Memory" app.

    Note that a user-installable application (without AllFiles/TCB capabilities) does not have access to everywhere (without hacking the Symbian Platform Security, or getting AllFiles/TCB capabilities from the manufacturer).

    So, with documented/published APIs you "wipe" some things, but not everything.

    ok, can i ask, if it also clears the data on the physical disk?

    like disk drives, the data is written on them, will the function be able to clear them too?

    Hi,

    Yes, the *#7370# will clear all data on the Phone memory.

    *#7370#, Its like a clean format. You might lose all your data on the device.

    *#7780#, your purpose is not served as data like contact are still retained in the device.

    As you mentioned previously, data wiper which could perform clearing of recorded messages, contacts, etc can be written in PyS60.

    I hope that is what you meant by "write out", if not please let me know.

    IMHO, I think its not possible to retrive data, after it has been formatted.

    If you have a backup taken somewhere before formatting, you can restore some data.
