Abstract: Disclosed herein are a key generation apparatus and method based on machine learning. The key generation method includes generating, by first and second key generation apparatuses, first and second commit values, and uploading the first commit value and the second commit value to an external repository, training, by the first and second key generation apparatuses, a neural network so as to match weight values with each other, sharing, by the first and second key generation apparatuses, the first and second commit values with each other, comparing shared first and second commit values with uploaded commit values, and then verifying the commit values, and when verification of the commit values has succeeded, generating, by the first and second key generation apparatuses, hash values using the matched weight value, verifying whether the hash values are identical to each other, and generating a session secret key based on a result of verification.

Abstract: A method and apparatus for predicting the risk of the collision of an object are disclosed herein. The apparatus for predicting the risk of the collision of an object includes an information reception unit, an input processing unit, a risk calculation unit, and a provision unit. The information reception unit receives information transmitted by each of a plurality of heterogeneous transmission apparatuses. The input processing unit processes the information into input information required to calculate a degree of risk of a collision between objects. The risk calculation unit calculates the degree of risk of the collision between the objects using the processed input information. The provision unit externally outputs the degree of risk of the collision, and performs control so that the risk of the collision between the objects can be externally predicted.

Abstract: An apparatus and method for providing traffic control service are disclosed herein. The apparatus for providing traffic control service includes a multi-sensor fusion processing unit, an image object tracking and combination unit, and an information provision unit. The multi-sensor fusion processing unit generates the location information of a vessel by fusing radar information and automatic identification system (AIS) information together. The image object tracking and combination unit sets a detection area on a closed-circuit television (CCTV) image based on the information of the vessel, and detects the vessel by performing image processing within the set detection area. The information provision unit generates mapping display information based on the information of the vessel and the result of the detection achieved by performing the image processing, and displays the generated mapping display information within a CCTV screen, thereby providing traffic control service.

Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

Abstract: Disclosed herein are an order-preserving encryption method and apparatus. The order-preserving encryption method may include when plaintext data is received from a client, storing a ciphertext database (DB), generated by encrypting the plaintext data, and a search index in a server, when a request for a range search query is received from the client, converting the range search query into a search index query statement, querying the server including search indices for the search index query statement, and querying the ciphertext DB of the server for an index ciphertext received in response to the query, and decrypting a ciphertext received as a response from the ciphertext DB and then transferring a plaintext-type response to the query statement to the client.
