An authentication method and system for screening network caller ID spoofs and malicious phone calls includes a screening authentication system with a server that includes a login register interface, a data accessing interface, a data searching and comparing program, a data searching database, a labeling indication program, a registry coding module and a data searching coding module. Authentication data is generated by the registry coding module from a caller telephone number and caller login identification data input during registration. Corresponding authentication data contained in a network calling signal from a caller sending device is generated by a data searching coding module. A data searching and comparing program compares the authentication data and, if any discrepancy is found, a labeling indication program sends a “failed authentication” signal to the target network receiving callee so that a fraudulent call is detected.

The present invention relates to a dumbwaiter system which is capable of enabling users to automatically purchase and received goods in a residential area by being installed in a multi-dwelling building, and ensures the safety of the users by reducing contact with strangers and preventing crimes. To this end, a multi-stage dumbwaiter system, according to one embodiment of the present invention, comprises: a dumbwaiter having a body of which the inside is vacant the sides can be opened, and a horizontal movement device for carrying an object inside or outside; and a home case disposed on one side of the dumbwaiter, and having a body of which the inside is vacant and the sides can be opened and a home case movement device for carrying an object inside or outside, wherein the dumbwaiter delivers an object to the home case or receives an object from the home case.

The invention uses the phone number and the identifying codes as the network online dual authentication method. The card holder of the credit card registers the VBV or MSC network identity checking ''self-setting password'' to the card-issuing bank, the holder also provides a group of ''phone number and the identifying codes'' personal special online dual identity authentication data to the card-issuing bank; the data login is stored in the ''dual authentication database'' of the ''credit card dual authentication computer system'' of the card-issuing bank; while the card-issuing bank is processing the online card slotting, the bank informs the card holder in the short message way besides the ''self-setting password'' of the VBV or MSC network identity checking for the card holder; requiring to respond to the personal special online identity authentication data of the ''phone number and the identifying codes''; comparing to the ''phone number and the identifying codes'' in the ''dual authentication database'' as the card slotting transaction on the network for the card holder for the dual rechecking to confirm whether the invention is the network credit card transaction under the entitlement.

The present invention provides a card having password input keys, which can prevent duplication of a credit card, a cash card, or an electronic identification card by a unauthorized third party upon loss or theft of the card, and which is constructed so that a separate password, other than a password for card payment assigned when the card is issued, is set in the card, and a magnetic stripe card or smart card-type credit card, cash card or electronic identification card can be turned on / off when a correct password is input, thus implementing a plurality of security functions without requiring changes to be made to a conventional card terminal or various operating systems.

A foreign substance detection device for a card reader includes an emitting module (1), a receiving module (2) and a control processing module (3). The emitting module (1) is embedded on a wall surface of a card reader insertion opening (101) for emitting detection waves to a detection area (103) in front of the card reader insertion opening (101). The receiving module (2) is embedded on the wall surface of the card reader insertion opening (101) for receiving the detection waves emitted by the emitted the emitting module (1). The control processing module (3) identifies whether the receiving module (2) receives the detection wave reflected by the foreign substance in the detection area (103), and determines whether the foreign substance exists in the detection area (103) according to the determination result. A card reader socket which includes a case (100) and the foreign substance detection device is also provided.

The present invention provides a foldable unmanned home-delivered article storage box, which can be easily fixed / installed on the front door and uninstalled, as needed, and which can be unfolded and then folded conveniently and quickly, in order to store an article. The foldable unmanned home-delivered article storage box according to the present invention comprises: a back plate, which is formedto have a right turned-U-shaped section when seen from above, and which is installed in an upright position; a pair of side plates connected / installed to both end corners of the right turned-U-shapedback plate to be foldable, and which are installed such that the longitudinal middle parts thereof can be bent inwards and folded; a front plate formed in a shape corresponding to that of the back plate such that the opposite end corners of the pair of side plates are connected to both end corners of the front plate to be foldable, and which has a locking device installed on the upper end thereof;a bottom plate, one end corner of which is rotatably connected / installed to the lower end of the back plate, and which constitutes the bottom of a space formed when the pair of side plates are unfolded; and a cover plate, one end corner of which is rotatably connected / installed to the upper end of the back plate, which has a locking groove formed on the opposite end corner thereof such that the locking device is fastened thereto, and which covers the upper surface of the space formed when the pair of side plates are unfolded.
