    Re: Serious Concerns About Ovi Store and DRM FL

    what is the Samsung solution?
    Samsung created application protection mechanism named "Zirconia".
    Quick description:
    During application buying process buyer enters imei, which is saved on license server. When bought application is started on the phone, it checks if there is saved license key on the phone and when it's not, application try connect to the license server over internet. When application connects to server and checks if application was bought (basing on imei) it downloads license key and saves it in the phone.

    Samsung provides API for the Zirconia and static lib. Developer has to use this API to check license by simple function call and callback implementation.

    In my opinion this is very good solution and I think OVI should create similar process.
    I'm not using Samsung protection yet, but I think I will publish to Samsung and only demo to OVI.

    That sounds like a good protection solution. When you say you're only going to demo to OVI what do you mean exactly?
    Time-limited stuff? Limited functionality?

    Yes, time limited game play without possibility to transform this game to the full version (user cannot enter activation code to comply OVI terms). I think if someone will play game and want to get full version he can go to the company web page and download trial version, buy license code by credit card (or pay pal...) or go to the provided link to the samsung store.
    One disadvantage of this solution is that user which want to play full version of game has to download it again from other site than ovi and company has to maintain own activation code generation (in case we want other channel than Samsung store and Zirconia).
    I think this solution is good until ovi provide some licensing mechanisms.
    My idea is only theory, I didn't implement this (yet).

    Also there is another possibility: on company web page won't be any licensing mechanism provided by company, but link for example to other store which provides licensing mechanism (as I remember clickgamer provides some imei generation codes during applications buying).

    But will OVI allow you to advertise the URL of your company web page within the demo?

    Even if I won't provide company web page address, user will find it by google or similar search engine by company name, which must be provided in about section and on ovi pages.
    Also I think company web address can be provided, but direct link to the game page on company page not (not sure that, should be checked in terms and conditions).

    Hi,
    No you cannot have web page links to other than store.ovi.com.
    But you can use the product id eg
    http://store.ovi.com/content/7161A4CC93014A62E040050A85321071?clickSource=browse&contentArea=applications
    would be acceptable to browse to the paid version on ovi store

    Re: Serious Concerns About Ovi Store and DRM FL

    after reading this posts and checking out the OMA DRM specifications i decided to remove my app from OVI store. I do not want my app to spread freely on some warez site. Its ridiculous that one can not implement own licensing mechanisms in this store...

    Another issue: did this happen to other publishers as well: i am getting support requests from people that purchased my app on OVI -> but there is NO record that there was a sale, even days later. Additionally on any query i send about this to Nokia there is NO reply. Are they cheating developers for their hardly earned money?

    Re: Serious Concerns About Ovi Store and DRM FL

    Any progress on this issue?

    Alternatively, does Ovi provide any WEB-type service that can be used to receive real-time info about purchases of an application? (e.g. email, IMSI, msisdn or IMEI of the buyer). This could be used to send an activation code to the user (definitely not my preferred solution though!)

    Re: Serious Concerns About Ovi Store and DRM FL

    such a callback solution would be a very good solution. our application receives its license key via SMS from our server, with 1024bit asymmetric crypto -> very hard to impossible to write a keygen for that. no portal (like handango, ...) offers such secure keys.

    Re: Serious Concerns About Ovi Store and DRM FL

    I guess that this means that Ovi does not currently offer any means to know, in real time, who has purchased an app, so app activation for Ovi buyers is not possible either.
    So the only solution is to just take the risk

    That's, indeed, the way things are.

    Hi Eric, from time to time I take a look at this thread hoping to see some kind of news on the matter...
    Does Nokia still take in any consideration the Developer's concerns about the (in-)security offered by DRM FL?

    EDIT:
    The BlackBerry solution is really impressive and very flexible! I wish we could use something like that for OviStore apps.
    It could be added side-by-side to the DRM FL as option, so, developers who lack of skills for using the BlackBerry solution, could continue to use DRM FL.
    For sure it will bring new companies and new apps to the OviStore.
    Are there any reason not to provide this option to the developers?

    Question Re: Serious Concerns About Ovi Store and DRM FL

    Any update on this?
    Can't Ovi store make use of License Manager sitting on the device for a fool-proof solution?

    Regards,
    Sujith

    hope to see something similar soon also on OVI...
    licmax.com can also help here. We used it instead of maintaining our own license server - most convenient, 'cause it handle many store (App World, Mobihand, Handango,...)
