Abstract: A personalized data backup application logs all user actions performed with the user's electronic files. During operation, all files modified by user actions, such as sending messages, uploading images or videos, taking pictures/videos, posting on social networks or in the chats, activating voice or sensory devices, are detected. These files can be located on user's mobile device or computer system. Then, the user backups reflecting data modified by the user on different devices are used to identify user actions based on the modified user data. The user actions are then used to create and/or train a personal behavior avatar that can act as the user to perform some online or electronic action based on the user heuristic patterns stored into the avatar.
