A method for managing an object using a trace-identifier (T-ID) according to the present disclosure may comprise: updating T-ID information for the object at a timepoint at which the object is saved after the object is opened at an endpoint; writing the updated T-ID information as metadata of the object; and transmitting the metadata including the T-ID information to a server.

Abstract: Disclosed are a method and device for calculating a correlation between notes using a database constructed on a basis of artificial intelligence, and supporting a service for the notes on a basis of the calculated correlation. A method by which a note providing device that interworks with a user terminal provides notes, includes: constructing a keyword DB by extracting a keyword from a note generated through the user terminal and reflecting a weight calculated through machine learning using the extracted keyword; and calculating a correlation score for each of a plurality of target notes correlated with a reference note using the keyword DB. Therefore, the method and device for providing the notes using the artificial intelligence-based correlation calculation can more accurately recommend the correlated notes by reflecting the interaction of the user.

Abstract: Disclosed are a method and an apparatus for de-identification of personal information. The method for de-identification of personal information comprises the steps of: obtaining, from a database, a raw table including records in which raw data indicating the personal information is recorded; generating generalized data by generalizing the raw data recorded in each of the records included in the raw table; setting a generalized hierarchical model consisting of the raw data and the generalized data; generating a raw lattice including a plurality of candidate nodes on the basis of the generalized hierarchical model; and setting, from among the plurality of candidate nodes included in the raw lattice, a final lattice including at least one candidate node satisfying a predetermined criterion. Thus, it is possible for the personal information to be efficiently de-identified.

Abstract: A technology related to a method and apparatus for providing a relation note using correlation is disclosed. The method for providing the relation note, which is performed by a relation note providing server interworking with a user terminal, comprises the steps of: receiving one or more generated notes from the user terminal; updating, according to a configurable reference, correlation between notes indicating a relation between the one or more notes; and providing the one or more notes to the user terminal on the basis of the correlation between the notes. Therefore, the method may provide a user interface which is intelligent and smart to enable a plurality of notes to be more effectively identified and managed on the basis of the correlation.

Abstract: The present disclosure relates to a method for analysis on interim result data in a de-identification procedure, an apparatus for the same, a computer program for the same, and a recording medium storing computer program thereof. A method for de-identification according to an example of the present disclosure may include: generating a first interim result data by applying a first de-identification process to an initial data; generating a first analysis metric for the first interim result data; and generating a final result data based on the first interim result data, when the first analysis metric satisfies a first de-identification criterion.

Abstract: The present disclosure provides a virtual file management method and apparatus, and a computer-readable recording medium thereof, which may comprises obtaining an object identifier for distinguishing objects, wherein the object includes at least one of a virtual file or a virtual folder and obtaining the object based on the obtained object identifier.

Abstract: A method for providing a software service of a license management server is disclosed. The method comprises the steps of: receiving a virtual machine interface from a cloud server; installing software of a service provider in the virtual machine interface; transmitting a license to the virtual machine interface; providing ID and password related authority to a user terminal; and providing a service of the software to the user terminal through the virtual machine interface when the user terminal accesses the software. Therefore, source code leakage due to static analysis can be fundamentally prevented.

Abstract: A system and method of protecting digital media contents, which maintain compatibility with an existing system and block any attempt to illegally use the digital media contents having various formats, and which reduce a system load and maximize a possibility of reusing the digital media contents. The system includes a packager for analyzing a format of contents and encoding at least a portion of a data region located in a payload of the contents, and for generating encoded contents by inserting encoding information including at least one of an encoding key value and contents information into the contents; and a digital rights management (DRM) server for receiving a request for a license and the encoding information from an external device which receives the encoded contents, for confirming the encoding information and then generating a license which is used to decode the encoded contents, and for providing the generated license to the external device.
