Abstract: An apparatus and a method for processing an application in a mobile terminal are provided. The method includes loading, by a bootloader upon system booting, a kernel, determining whether the kernel is modified, creating, when the kernel is modified, kernel verification information indicating a custom kernel, encrypting the kernel verification information, and sending the encrypted kernel verification information, activating, by a kernel handler, the kernel, and receiving the kernel verification information from the bootloader, and forwarding the kernel verification information, decrypting, by a rooting detector, the kernel verification information into kernel status information and delivering the kernel status information when a specified Application Programming Interface (API) is invoked, and invoking, by an application handler, the API when an application is executed and controlling an execution of the application when the kernel status information indicating the custom kernel is received.

Abstract: An electronic device includes a memory and a processor. The memory includes a data partition, a key storage partition, and a key backup partition. The processor operatively connected to the memory. The processor is configured to generate an encryption key with respect to at least one data folder generated in the data partition to store the encryption key in the key storage partition. The processor is also configured to store a backup encryption key equal to the encryption key, in the key backup partition. The processor is further configured to store an integrity file including a checksum of the encryption key in the key backup partition.
