In this paper, the FIDO (Fast IDentity Online) transaction certification platform was proposed for applying the DID (Decentralized ID) of blockchain with home shopping channels to the IPTV service providers based on the Remocon (Remote Control). In this case, the DID based smart remocon applies biometric identification techniques for personal identification. These individual DID smart remote controls apply distributed ID blockchain, enabling home shopping viewers to conduct reliable ratings surveys through the detection of channel changed information. In addition, this smart remocon utilizes the product purchased information history on home shopping channels, allowing IPTV's home shopping viewers to compare the same broadcasted production information on all channels by blockchain technique and their production characteristics. IPTV service providers can process home shopping order/authorization informations in one-stop service via a number of home shopping broadcasting companies, and DID smart remote controls for home shopping viewers with the checking results of their real-time online access to confirm the FIDO2.0 transaction certification homepage. Thus, the FIDO transaction authentication platforms of IPTV service provider(Telecommunication company) can be expected to improve the benefits of home shopping customers, and to reduce the broadcasting companies' burden of payment, too.

Along with the recent worldwide development of fintech, FIDO (Fast IDentity Online) using biometric technology is rapidly growing in the mobile payment market, replacing the existing password system. This FIDO authentication must be processed in a reliable environment that requires high level of security, as sensitive biometrics is being processed. However, this environment is currently dependent on the manufacturer as it is supported by certain hardware on the smartphone. Therefore, this thesis proposes a server-based authentication model using distributed management of compliance based biometric information that can be used universally safely without the need for specific hardware in mobile environments.

The national accredited certificate is a user certificate issued based on the user's personal information, which has been identified in advance, and has become a universal authentication method used for most electronic financial transactions and user authentication. And it contributed a lot to the use of e-government and domestic service. However, due to the lack of web standards on how to use, it was inconvenient to install a separate plug-in, and efforts to improve it have been continued. In this paper, we attempt to solve the problem of certificate usage environment by presenting the certificate digital signature method using the extension of the FIDO2 (Fast Identity Online v2) client to authentication protocol (CTAP) specification.

This paper utilizes the FIDO methodology (Function, Information, Dynamic, Organization modeling) which is an enterprise modeling tool that can describe inter-organizational interaction (specifically between prime and sub contractors in this experiment). FIDO follows the standard IDEFO rules in order to demonstrate how a cascading information flow can evolve from a customer to a prime to a subcontractor in a concurrent manner, in a supply chain environment. Background on these processes is presented, followed with the newly derived process and methodology. This is presented in a supply chain management context, and results from an actual experiment at Motorola utilizing subcontractors that supply custom machine parts is presented and reviewed.

Recently, there has been a lot of ongoing research regarding financial transactions and payments due to the emergence of financial technology (FinTech). Payments have been processed through cash and credit cards, and payment methods have been simplified and are more convenient, with mobile payment via mobile cards and mobile phones. This study offers a new mobile payment method by using a mobile phone instead of a card reader or terminal. For payments, authentication is processed with the user's biometrics and a built-in fingerprint scanner, and the payment is processed after receiving an authentication code issued by the authorizing institution to confirm the user's identity. User biometrics and payment information is secured from any kind of malicious hacker by saving it in a Fast Identity Online (FIDO) Trusted Execution Environment (TEE) section in a smartphone. Regarding key security, every key is securely created in the FIDO TEE section, providing secure mobile payment by neutralizing various malicious attacks, including sniffing and the man-in-the middle attack.

Acquisition of the FIDO authentication technology in pursuit of improved security function of the NFC-based 2 factor electronic payment system enabled GenoTech Ch., Ltd. to develop its new service, Gallery-Auction, demoed at Daegu Exhibition. The demonstration was followed by the improvement requests in banner creation & installation, changes in UI, changes in order of operation, etc, which were taken into account for the succeeding update. During the second demonstration held at 'Art: Gwangju: 17,' it analyzed and visualized the number of visitors per hour there.

Lately weight for smartphone mounted to function for NFC is increasing, rapidly. Because of this, NFC related technology is made by many companies. We developed Gallery-Auction for security enhancements and new services of NFC-based 2 factor electronic payment system. Enhanced security features development of user authentication module through fingerprint recognition to apply FIDO authentication technology and developed electronic contract voice service of Gallery-Auction using TTS(Text to Speech). Therefore we enhanced convenient and simple authentication method and security through NFC mobile electronic payment.

Recently, a number of military intranet infiltrations suspected of North Korea have been discovered. There was a problem that a vulnerability could occur due to the modification of user authentication data that can access existing military information systems. In this paper, we applied mutual verification technique and API (Application Programming Interface) forgery / forgery blocking and obfuscation to solve the authentication weakness in web browsers that comply with FIDO (Fast IDentity Online) standard. In addition, user convenience is improved by implementing No-Plugin that does not require separate program installation. Performance tests show that most browsers perform about 0.1ms based on the RSA key generation rate. In addition, it proved that it can be used for commercialization by showing performance of less than 0.1 second even in the digital signature verification speed of the server. The service is expected to be useful for improving military information system security as an alternative to browser authentication by building a web secure storage.
