Electronic device and method for controlling thereof

An electronic device, comprising:

• a memory comprising a neural network model trained to identify private information of a user of the electronic device comprised in an image;
• a display;
• a communicator comprising circuitry;
• and
• a processor configured to:
• based on a user command to transmit a first image to an external device being input, identify whether the private information of the user is comprised in the first image by inputting the first image in the neural network model,
• based on identifying that the private information of the user is comprised in the first image, control the display to display a first user interface (UI) asking whether to process at least one piece of the private information based on the private information comprised in the first image, and
• based on a user command input through the first UI, process the first image and control the communicator to transmit the processed first image to the external device.
