Currently, about 79% of computers types in domestic companies are desktop. Desktops used by most companies have the problem that unauthorized users can access the desktop by booting. To complement these vulnerabilities, BIOS password and user account login have been used. But they are vulnerable because of bypassing authentication. In this paper, we proposed a remote booting system that uses fingerprint recognition and power control to complement the physical access to the desktop. The proposed system uses fingerprint recognition technology for user authentication. And it overcomes vulnerability of physical access to the system by controlling power. Proposed system enables secure remote booting against physical vulnerabilities on desktop.

SaaS, ERP and CRM have been fused together to become SaaS ERP and SaaS CRM in cloud computing. Even though they provide advanced services than before, companies must entrust their inside information to SaaS provider. And the threats for entrusted information disturb to use SaaS ERP and SaaS CRM. We analyzed threats for SaaS by attack scenarios, and proposed a secure system which store company’s data to database in DMZ. Companies need not entrust their information to SaaS provider. We encrypted information of database with fully homomorphic encryption to guarantee security. Since Fully Homomorphic Encryption is cryptographic System that makes operation possible without having to decrypt encrypted data, It is expected to fit in environments without data consignment.
