About Crack Proof for Android

Background of development

Android™ has received attention as an OS for smart phones and mobile devices.
Since Android uses a Java-like language there are many application developers and it has rapidly become popular.

However, as most of the applications that operate on the Android OS are developed with intermediate code, they are very vulnerable to cracking (improper analysis and alteration etc.).
In addition, it is possible to easily take out applications to a PC unlike conventional mobile phones. By taking out an application to a PC there is the possibility that various kinds of damage maybe encountered such as DRM removal or the application is converted into malware etc.

In the future this problem will become more critical the more Android spreads.
Crack Proof for Android is a unique concept of tamper-proof security software developed in order to protect applications from the threat of cracking.
