Abstract: Provided is an automatic pseudonymization technique recommendation method using artificial intelligence, including receiving a training dataset including a plurality of pieces of data including a column name, a data type, a pseudonymization technique recommendation, adding, a data type vector obtained from the data type to a word vector obtained corresponding to the column name to obtain a numeric vector, and labeling the numeric vector with the pseudonymization technique recommendation to generate a plurality of pieces of training data, training a first learning model using the plurality of pieces of training data so that the first learning model outputs a pseudonymization technique recommendation in response to an input of the numeric vector, obtaining a numeric vector corresponding to each column of the dataset to be pseudonymized, and inputting the numeric vector obtained into the trained first learning model to obtain a pseudonymization technique recommendation for each column of the dataset.
