Patent ID: 11341253

Abstract:
A control method of a terminal apparatus is disclosed. A control method of a terminal apparatus comprises the steps of: determining the number of different ciphertexts, into which behavior data generated according to operation of the terminal apparatus by a user is to be encrypted, for each data type of the behavior data; generating ciphertexts by encrypting behavior data of an identical type in a unit of the determined number of the different ciphertexts so that the behavior data can be encrypted into different ciphertexts; transmitting the generated ciphertexts to an external server; when a model of the behavior data having been used to acquire learning on the basis of the transmitted ciphertexts is received, monitoring an operation of the terminal apparatus on the basis of the received model. Here, the model may be obtained through acquisition of learning according to at least one of a machine learning algorithm, a neural network algorithm, and a deep learning algorithm.
