Abstract: Disclosed herein are an apparatus and method for managing personal information. The method includes a step in which a user terminal device registers the decentralized identification information of a user in a blockchain, receives the personal information of the user, stores the same in an endpoint for managing the personal information, and registers a personal information access policy for the personal information in a first server; a step in which the apparatus receives the decentralized identifier of the user, retrieves the decentralized identification information of the user, corresponding to the decentralized identifier, from the blockchain, and requests a personal information access token for accessing the personal information from the first server using the decentralized identification information; and a step in which the apparatus identifies the endpoint from the personal information access token, which is generated based on the personal information access policy, and retrieves the personal information from the endpoint.

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: Disclosed herein are an apparatus and method for generating evidence video. The apparatus includes a video object indexing unit, a video object search unit, and an evidence video generation unit. The video object indexing unit recognizes an object by storing and analyzing videos received from multiple surveillance cameras, extracts the features of the recognized object, and then generates object metadata. The video object search unit compares received search conditions with the object metadata, and then outputs search results, including the feature information of at least one object, which corresponds to the search conditions. The evidence video generation unit generates an evidence video by aggregating only videos including a specific object selected from the search results.

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.
