TL;DR: In this article, a transaction information managing system including a plurality of servers and at least one third-party server is presented, where the plurality servers are configured to create, when transactions using the budget of the public organization occurs, a block based on transaction information of the transactions, add the block to the block chain, and share the block with the third party server.

TL;DR: In this paper, the authors present a protocol for FIDO universal authentication using a blockchain, which includes sending, by the terminal apparatus, a FIDOD service request for any one of FIDOV registration, FIDOC authentication, and FIDOR deregistration for an application service provided by the server apparatus to the server, and verifying, by blockchain, a response message, which is created as a result of local authentication of a user in the user in response to the FOV service request.

TL;DR: In this article, a face recognition based key generation apparatus controls a key generation model that is formed of a CNN and an RNN to be learned to generate a desired key having a consistent value by using sample facial images of a key owner and a PIN of the key owner as inputs.

TL;DR: The experiments show that the proposed loss function is visibly superior to the ability to classify digit images and the experimental results indicate that Arcface loss and Additive-Margin loss functions satisfy predefined test accuracy most quickly under two and three dimensional embedding, respectively.

TL;DR: This paper presents a new biometric-based key derivation function (BB-KDF), which users are able to derive cryptographic keys solely from their own biometric data: users do not need any other user-specific helper information.
