Abstract: Disclosed herein is a method of decoding an image. The method includes generating an inter prediction block by performing inter prediction with respect to a current block, generating an intra prediction block by performing intra prediction with respect to the current block, determining a first weight and a second weight, and generating a final prediction block by respectively applying the first weight and the second weight to the inter prediction block and the intra prediction block. The generating of the intra prediction block includes generating the intra prediction block using a predefined intra prediction mode.

Abstract: Disclosed are a point-of-care system and method, the system including: an aptamer-based diagnostic reagent; a diagnostic instrument for detecting a Raman signal through a Raman analysis technique; and a diagnostic kit to be operated on the basis of a lateral flow method, wherein blood and the diagnostic reagent are reacted so as to detect a Raman signal when the placement of the diagnostic kit is detected, thereby allowing the type of acute febrile illness to be identified.

Abstract: Incidents involving confidentiality and vigilance against user privacy invasions raise doubts as to current third-party data collection procedures. Personally identifiable information (PII) is being abused for medical data breaches, identity theft, spam, phishing, cyber spying, etc. A great amount of data is flowing from users to companies for prediction and analysis of data-centric markets. It is thus difficult to track PII flow and genuineness. Blockchain technology, which is an “immutable” distributed ledger, can efficiently track PII exchange, storing, and distribution. In contrast, the EU general data protection regulation (GDPR) in progress claims “a right to forget” and a right “to delete”. However, the present specification proposes an off-chain blockchain architecture using both a local database and a distributed ledger to guarantee a trustable PII life cycle.

Abstract: Big data analytics is being used by many market participants. PII (Personally Identifiable Information) (e.g., age, race, social security number, address, etc.) plays a vital role in providing user-centric services. Many IT companies collect, store and process PII of their customers by means of various mobile applications. The example embodiments may explain how collective permission gathering through multiple Android applications by same publishers can disclose user's PII by using two new PII risk factors, and determine total risk factor for PII.

Abstract: An apparatus and a method for decrypting cryptogram through steps of: dividing a cryptogram received from a server into a first cryptogram and a second cryptogram; transforming the first cryptogram and the second cryptogram by using a predetermined inverse transform; and decrypting the cryptogram to generate a plaintext based on a Feistel network including XOR operations between the transformed first cryptogram and a round key generated from a secret key and between the transformed second cryptogram and the round key are provided.

Abstract: Disclosed herein are method and system for modifying transactions already recorded on blockchains. The method for managing transactions based on blockchains may include a process for proceeding with mining blocks by separating approval and modification of transactions by using transaction approval block for proving approval of transactions and transaction modification block for proving modification of transactions.

Abstract: A method and system for protecting copyright of digital contents and contents themselves which are distributed. A user receives the encrypted digital contents and encrypted decryption key capable of decrypting the encrypted digital contents. A key is generated from the system information representing a user personal unique system characteristic and the encrypted contents decryption key is decrypted. Decrypting the encrypted contents decryption key is proceeded only when a key generated by extracting information of a personal system of the contents to be used by a user is identical to a decryption key of the encrypted contents decryption key. When the contents decryption key is decrypted, the encrypted contents are decrypted and generated using the above decrypted contents decryption key.
