Basic precautions to prevent piracy?

阅读更多关于 Basic precautions to prevent piracy?

问题 It's my first app and I am concerned about piracy. I know it's not possible to fully prevent it but I would like to make it as hard that the hacker wouldn't simply find it worth. I have read some older threads but I don't know how secure Android and libraries like LVL are today. So far, I have only implemented Proguard and LVL. What are other ways that people can crack my app besides reverse engineering and what can I do to make it hard? Also, I asked another question specifically about lucky

问题 I'd like to sell my Android application, but I live in Poland and in my country* Android Market supports only free apps (we cannot sell and we cannot buy too). What is the best way to sell application in such situation? I can accept PayPal money transfers, but I don't know how to distribute APK package without exposing it to getting pirated. Did someone tried it already and succeeded? * Author's country wasn't supported at the moment of asking ** You may find useful PayPal Mobile Payments

Get fileSize of info.plist to prevent piracy

阅读更多关于 Get fileSize of info.plist to prevent piracy

问题 I'm trying to put anti-piracy code in my app. The previous answer to this (which I can't link to because of my member status - sucks) can be easily countered, since the "SignerIdentity" string can be looked for and replaced in the binary using a hex editor. Instead, checking the fileSize of the info.plist file and comparing it to a reference value sounds more solid (since the info.plist is getting modified here and there when cracking the app). How would I do that? I tried the following but

USB software protection dongle for Java with an SDK which is cross-platform “for real”. Does it exist?

阅读更多关于 USB software protection dongle for Java with an SDK which is cross-platform “for real”. Does it exist?

问题 What I'd like to ask is if anybody knows about an hardware USB-dongle for software protection which offers a very complete out-of-the-box API support for cross-platform Java deployments. Its SDK should provide a jar (only one, not one different library per OS & bitness) ready to be added to one's project as a library. The jar should contain all the native stuff for the various OSes and bitnesses From the application's point of view, one should continue to write (api calls) once and run

问题 I'm building a blacklisting service for cracked iPhone apps and I am curious if I missed a method for detecting cracked apps. In the moment following app crack detection methods are available for the service: checking plist size checking signer identity checking if binary is crypted (not sure if this is working correctly since no cracked app got detected this way) checking modified date of info.plist against modified date of package (not sure if this is working - used code like: http:/

阅读更多关于 Piracy protection using USB based hardware solution

问题 i want to protect my Java product by using some USB-based authentication and password management solution like you can buy it here: aladdin This mean that you have to connect a USB stick with a special software on it, before you can start your application. I would like to here some experience of users which have used hardware like this. Is this as safe as it sounds? General: How much money you would spend to protect a software which would sell 100 times? I will obfuscate my Java code and save
