1. A display apparatus comprising:
a display;
at least one processor configured to execute one or more instructions to separately run a normal operating system (OS) and a secure OS, which respectively are to operate in a normal world (NWD) and a secure world (SWD) corresponding to a TrustZone,
wherein the processor is configured to:
identify whether input data, input to a deep neural network (DNN) including a plurality of hidden layers between at least an input layer and an output layer, corresponds to and/or comprises security data;
based on a determination that the input data corresponds to and/or comprises security data, control the secure OS so that layers from the input layer of the DNN to at least one hidden layer connected to the input layer are to be driven within the SWD; and
based on a determination that the input data does not correspond to and/or comprise security data, control the normal OS so that the entire DNN is to be driven in a world other than the SWD.
