The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.

Abstract: Disclosed herein are an apparatus and method for managing personal information.

Abstract: Disclosed herein are an apparatus and method for recommending privacy control. A privacy control server includes multiple common privacy control recommendation models learned based on personal information provision histories of multiple users, a user preference determination unit for generating at least one question item based on the multiple common privacy control recommendation models and determining a privacy control preference of a user based on a result of a user answer to the at least one question item, and a common privacy control recommendation model provision unit for providing a common privacy control recommendation model selected to match the privacy control preference of the user to the user.

Abstract: Disclosed are a device and method for managing credentials. In a multi-decentralized identity management service environment, a user can safely manage credentials that have been once issued, and can use the credentials in various user terminals without being redundantly issued credentials.

Abstract: The present invention relates to a composition, a kit, a nucleic acid chip, and a method capable of diagnosing colorectal cancer, rectal cancer, or colorectal adenoma by detecting the methylation level of CpG sites in a GLRB gene. Accordingly, colorectal cancer, rectal cancer, or colorectal adenoma can be diagnosed not only accurately and quickly, but also at an early stage.

Abstract: Disclosed herein are an apparatus and method for issuing delegated credentials between digital wallets possessed by multiple users connected to a Decentralized Identifier (DID) registry through wired/wireless communication. The method includes receiving, by a digital wallet of a first user, a delegated credential issuance request message including a newly created DID document from a digital wallet of a second user, generating, by the digital wallet of the first user, a delegated credential using both the delegated credential issuance request message, received from the digital wallet of the second user, and an original credential, previously issued by the digital wallet of the first user, and transmitting, by the digital wallet of the first user, the generated delegated credential and the original credential, together with a delegated credential registration request message, to the digital wallet of the second user.

Abstract: The present invention relates to a composition, a kit, a nucleic acid, and a method capable of diagnosing bladder cancer by detecting the methylation level of a CpG site of at least one gene selected from the group consisting of IFFO1, MARCH11, BARHL2, NR2E1, KCNA3, and BOLL. According to the present invention, since the hypermethylation of a CpG site of a gene is specifically exhibited in bladder cancer, a composition, a kit, a chip, or a method according to the present invention can be used to accurately and rapidly diagnose bladder cancer and to be used for early diagnosis and monitoring recurrence.
