Then, as shown in Equation 5, the first client terminal 140 generates the row vector having each digit constituting the first one-time authentication number as a component, and among the p rows constituting the random matrix, By inserting the row vector at the predetermined position, the insertion matrix of (p+1) x m can be generated, and as shown in Equation 7, the insertion matrix and the first authentication matrix stored in the memory may be multiplied by to generate the operation matrix.

Thereafter, the first client terminal 140 may calculate a second Euclidean distance between the first column vector and the second column vector constituting the two columns of the operation matrix and feed it back to the advertising agency service device 110 . have.

In this way, when the second Euclidean distance is fed back to the advertising agency service apparatus 110 in response to the feedback request of the Euclidean distance from the first client terminal 140 , the Euclidean distance check unit 130 is the first Euclidean distance and check whether the second Euclidean distance is equal to each other. At this time, when it is confirmed that the first Euclidean distance and the second Euclidean distance are identical to each other, the authentication completion unit 131 completes the authentication of the first client terminal 140 .

That is, that the first Euclidean distance and the second Euclidean distance are confirmed to be the same means that the first client terminal 140 and the advertisement agency service device 110 share the same OTP generation function and the same authentication matrix. means, the authentication completion unit 131 may complete the authentication of the first client terminal 140 when it is confirmed that the first Euclidean distance and the second Euclidean distance are the same. In this way, when authentication of the first client terminal 140 is completed, the recommended advertisement information transmitting unit 113 selects the k pieces of advertisement information from the advertisement information database 112 as recommended advertisement information and then selects the k advertisement information as the recommended advertisement information. The k pieces of advertisement information may be transmitted to the first client terminal 140 .
