摘要:
An authentication system that uses personal variable biometric information which changes according to times and environments, and an authentication method using the same are disclosed. The variable biometric information-based authentication system includes: a mobile terminal configured to generate information regarding an ID that intends to access a facility or information requiring an access authority, and to collect variable biometric information, such that information regarding the ID and the variable biometric information are stored all together; and a variable biometric information management server configured to, when the mobile terminal requests a login command regarding the ID, verify validity of the login command regarding the ID based on the variable biometric information. Accordingly, a real data value of collected biometric information is not used in the authentication procedure, and the authentication procedure is performed only by using a figure or a form of a graph indicating a variation in a specific section or a data arithmetic value obtained by performing a predetermined arithmetic operation with respect to the real data value. Therefore, even if the biometric information used in the authentication procedure is leaked, a damage resulting therefrom can be inhibited. In addition, since a security level of the authentication procedure can be selectively determined, the security of the authentication procedure can be enhanced by combining different types of variable biometric information or by combining variable biometric information of a plurality of users. In addition, as the security level of the authentication procedure is selectively determined, the authentication procedure can be diversely utilized in an entering authentication to a facility such as an office or school or secure authentication in financial services such as account transfer, payment, etc.

A complex authentication system that uses personal variable biometric information which changes according to times and environments, and a complex authentication method using the same are disclosed. The variable biometric information-based complex authentication system includes: a mobile terminal configured to collect variable biometric information; a variable biometric information management server configured to store the variable biometric information received from the mobile terminal; and an agent server configured to, when the mobile terminal requests a login command regarding the ID, verify validity of the login command regarding the ID based on the variable biometric information. Accordingly, even if biometric information used in an authentication procedure is leaked, a damage resulting therefrom can be inhibited, and security of the authentication procedure can be enhanced by combining different types of variable biometric information or by combining variable biometric information of a plurality of users.

摘要:
A method for controlling a bus in a digital interface is disclosed. In the present method, after a self identifying process when a bus reset occurs, a determination is made whether a node which needs to transmit isochronous data is a new node which needs to newly transmit isochronous data or a previously connected node which had been transmitting isochronous data before the bus reset. Thereafter, priority is given to previously connected nodes in allocating channels and bandwidth to previously connected node(s).

A semiconductor device package includes an integrated circuit chip having a plurality of chip pads thereon, and a plurality of ball pads rerouted from the chip pads, and a substrate including a plurality of substrate pads thereon. Solder joints, each physically and electrically connecting a ball pad and a substrate pad, are between the to package and the substrate. A stress-relieving film, which can be a polyimide or other dielectric film, lies away front amend between the package and the substrate. A plurality of via holes or metal regions are in the film at positions corresponding to the solder joints. The solder balls are formed on the package and the substrate or only on the package. The solder joints are through the via holes or attached to the metal regions. The stress-relieving film thus attaches to the solder joints and distributes stress in the solder joints over the stress-relieving film to reduce the probability of cracking the solder joints. The stress-relieving film does not contact the package and the substrate and thereby avoids causing interface delamination.
