Abstract: Disclosed herein are an apparatus and method for providing an anonymous delegated credential in a DID-based service. A method for issuing an anonymous delegated credential in a DID-based service includes receiving an anonymous delegated credential issuance request message from a digital wallet of a delegate, setting attribute values in the anonymous delegated credential, anonymizing delegator identification information and delegatee identification information among the attribute values, and issuing the generated anonymous delegated credential to the digital wallet of the delegatee.

Abstract: The present invention relates to a method for predicting the prognosis of a breast cancer patient. More specifically, to provide information needed to predict the prognosis of a breast cancer patient, the method for predicting the prognosis of breast cancer including the following steps of the present invention comprises: (a) obtaining a biological sample from a breast cancer patient; (b) measuring the mRNA expression level of matrix metallopeptidase 11 (MMP11) and the mRNA expression level of cluster of differentiation 2 (CD2) from patient information or the sample of step (a); (c) normalizing the gene mRNA expression levels selected and measured in step (b); and (d) predicting the prognosis of breast cancer by combining the gene expression levels normalized in step (c), wherein overexpression of the MMP11 indicates a bad prognosis, and overexpression of CD2 indicates a good prognosis.

Abstract: The present invention relates to a composition, a kit, a nucleic acid chip and a method, for diagnosing colorectal cancer, rectal cancer or colorectal adenoma by detecting the methylation level of CpG sites in a LINC01798 gene, in which colorectal cancer, rectal cancer, or colorectal adenoma can not only be diagnosed accurately and rapidly, but can also be diagnosed early.

Abstract: Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. 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.

Abstract: Disclosed herein are an apparatus and method for managing a history of object owners. The method includes generating, by an object owner history management apparatus, a product registration Verifiable Credential (VC) in a form of a Merkle tree, and registering the product registration VC in a blockchain in order to manage a history of owners of an object, acquiring, by a first user terminal device, the product registration VC from the blockchain and registering a first owner VC, generated based on the product registration VC, in the blockchain to register an ownership of the object, and acquiring, by a second user terminal device, a product transfer Verifiable Presentation (VP) from the first user terminal device and registering a second owner VC, generated based on the product transfer VP, in the blockchain to receive transfer of the ownership of the object.

Abstract: The present invention relates to a method of predicting the effectiveness of chemotherapy in a breast cancer patient, and more particularly, to a method for predicting the effectiveness of chemotherapy by measuring the expression levels of genes for predicting prognosis of breast cancer and a standard gene in a biological sample obtained from the breast cancer patient, and a method for predicting the difference between a patient group having a high effectiveness of chemotherapy and a patient group having a low effectiveness of chemotherapy. Therefore, the method of the present invention can accurately predict the effectiveness of chemotherapy for the breast cancer patient and can be used for the purpose of presenting clues about the direction of breast cancer treatment in the future.
