Abstract: A method may be performed using a server. The method may include receiving an identity authentication request associated with a user, generating authentication information based on the identity authentication request, and generating candidate information based on the authentication information such that the authentication information is a subset of the candidate information. The candidate information may be displayed at a randomly selected location. The user may provide input through a graphic input interface to select the authentication information from among the candidate information.

Abstract: When a security authentication request sent by a terminal is received, an identity authentication solution includes acquiring network environment information and user behavior data according to the security authentication request, then determining, according to the network environment information and the user behavior data, whether a current operation is a machine attack, and acquiring a CAPTCHA of a predetermined type according to a predetermined policy and delivering the CAPTCHA to the terminal if the current operation is a machine attack, to perform identity authentication, or determining that security authentication succeeds if the current operation is not a machine attack.

Abstract: A two-varying-password generator having two varying passwords of different digit lengths and different time intervals is disclosed. A two-varying-password generator has a printed circuit board where a processor is soldered onto, a battery, a display window and an on/off key and code key. The processor is loaded with two predetermined programs that can produce two passwords (or more than two passwords) of different digit length and different time interval. Meanwhile, the host computer also stores these two programs in the customer's account. As the clocks of both two-varying-password generator and host computer work in synchronously, both of them can produce two identical passwords of the same moment. Application of two-varying-password generator can counter phishing sites, fight credit card forgery and unauthorized transaction, tackle cloned ATM card.

Abstract: A two-varying-password generator having two varying passwords of different digit lengths and different time intervals is disclosed. A two-varying-password generator has a printed circuit board where a processor is soldered onto, a battery, a display window and an on/off key and code key. The processor is loaded with two predetermined programs that can produce two passwords (or more than two passwords) of different digit length and different time interval. When on/off key is pressed, the processor is activated and produces two passwords of the current time using the two predetermined programs loaded in the processor. The two passwords are the functions of time, which are defined by two predetermined programs respectively. Meanwhile, the host computer also stores these two programs in the customer's account. As the clocks of both two-varying-password generator and host computer work in synchronously, both of them can produce two identical passwords of the same moment.

Abstract: A refrigerator having a middle fresh food compartment and a relatively large bottom freezer compartment arranged below the fresh food compartment and a relatively small freezer compartment arranged above the fresh food compartment. The bottom freezer compartment preferably supports a drawer including a frame and a removable bin. Cool air can be supplied to the compartments of the refrigerator by employing a two fan control system such that no electromechanical baffles are required. Alternatively, cool air can be directed to the compartments of the refrigerator by use of a baffle which requires only a single electromechanical device to control air flow into three different compartments. The baffle includes a main rotary damper which can be positioned to provide proportional amounts of chilled air to the three separate compartments based on the degree of cooling required.
