A semiconductor device structure, for example a 3D structure, and a method for fabricating a semiconductor device. As non-limiting examples, various aspects of this disclosure provide various semiconductor package structures, and methods for manufacturing thereof, that comprise interposer, interlayer, and/or heat dissipater configurations that provide for low cost, increased manufacturability, and high reliability.

Semiconductor package and fabricating method thereof

The present disclosure relates to a method for managing an object, an apparatus for the same, a computer program for the same, and a recording medium storing computer program thereof. 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.

Method for object management using trace identifier

A method of distributedly storing data in a system comprising a plurality of edge nodes communicatively coupled to an end device and a central cloud. The method includes: receiving, by a first edge node, data transmitted by the end device; assigning, by the first edge node, a data tag to received data according to attributes of the received data and duplicating the received data to generate a tagged data copy; and transmitting, by the first edge node, the tagged data copy to at least one second edge node determined by a data distribution policy determined by the central cloud directly or through the central cloud, so that the at least one second edge node store the tagged data copy in a storage.

Method and device for distributed data storage

Disclosed are an apparatus and method for managing a digital copyright on electronic publication (EPUB)-based content and an apparatus and method for providing EPUB-based content according to a user's right. An encryption unit of the apparatus for managing digital copyright generates encrypted unit files by encrypting a plurality of unit files included in content in the form of a compressed archive including the plurality of unit files with different encryption keys, stores the encrypted unit files in a content database, generates mapping data by mapping the encryption keys to pieces of identification information of the encrypted unit files, and stores the mapping data in an encryption key database. A rights management unit transmits an encryption key selected from among the plurality of encryption keys to a content provision apparatus, which decrypts the encrypted unit files and provides the unit files to a user, based on at least one of identification information of the user and identification information of the content included in an encryption key provision request message received from the content provision apparatus.

Apparatus and method for managing digital copyright on EPUB-based content, and apparatus and method for providing EPUB-based content according to user's right

Provided is a clipboard security system and method for improving security of data transmission made through a clipboard which is frequently used in utilization of a computer. An example of the clipboard security system includes a clipboard managing unit for storing data in a clipboard or extracting data from the clipboard in response to a request from one or more objects, in which the clipboard managing unit includes a data encrypting unit for encrypting the data for which storage is requested according to a trust relationship of an object which desires to store the data in the clipboard and a data decrypting unit for decrypting the encrypted data according to a trust relationship of an object which desires to extract the encrypted data stored in the clipboard.

System and method for clipboard security

The present invention relates to an apparatus and a method for managing digital rights using virtualization technique, and more particularly to an apparatus and a method for enabling a user to access a desired text file in an independent area through a virtual machine corresponding to a licensed right for accessing the text file. The present invention comprises a virtual machine (VM) management unit for controlling a user access authorization function for accessing the text file in the area to which the virtualization technique is applied.
