Abstract: A method for managing data, comprising: receiving data about information collected by a sensor, in which at least a part of the data is encrypted; and performing an analysis in a state where both non-encrypted section and encrypted section of the data are not decrypted. Also, a method for managing data encryption, comprising: allowing a sensor or an intermediate network device to encrypt at least a part of data about collected information; allowing the sensor or the intermediate network device to transmit the at least partially encrypted data; allowing a data management apparatus to receive the at least partially encrypted transmitted data; allowing the data management apparatus to store the at least partially encrypted received data; and allowing the data management apparatus to perform an analysis in a state where both non-encrypted section and encrypted section of the at least partially encrypted data are not decrypted.

Abstract: An encrypted data management method according to one embodiment of the present invention can comprise the steps of: receiving data classified into at least two data types and encrypted for each classified data type by different methods; storing the received data; and performing a search in the stored data.

Abstract: The present disclosure provides a light emitting diode and a method of manufacturing the same. The light emitting diode includes a graphene layer on a second conductive semiconductor layer and a plurality of metal nanoparticles formed on some region of the graphene layer, whereby adhesion between the second conductive semiconductor layer comprised of an inorganic material and the graphene layer is enhanced, thereby securing stability and reliability of the light emitting diode. In addition, the light emitting diode allows uniform spreading of electric current, thereby allowing stable emission of light through a surface area of the light emitting diode.
