Abstract: A system and method are disclosed to improve password security assigned to a user, the method comprising: a method for performing enhanced security authentication, the method comprises: generating one-time password, by a security server, by filtering original password characters, wherein a security server provides a display on a hardware display screen, in which a plurality of keys are arranged and at least one selected from the arranged keys is used to filter original password characters; storing, by a memory unit, the original password and the one-time password generated; determining, by the security server, whether a user's password entered on the hardware display screen be accepted by comparing the entered password with the one-time password. The system comprises a storage module and a computer program for performing the method.

Abstract: Methods and apparatus to generate a user-defined virtual signal to secure mobile payments are described. The apparatus can configure the features of the user-defined virtual signal to broadcast; generate a random string of numbers and characters forming the signal identity to broadcast; allow a user to determine the signal identification characters; allow the user to configure technical features of the transmitting signal; allow the user to determine the features of the transmitting signal to display on the device; display the configured feature of the signal to transmit to the user; and store the configured features of the generated signal into the memory, the signal transmitted to a receiver device.

Abstract: Disclosed are a one time password generation device and an authentication method. The one time password generation device includes: a reference information generator that generates reference information; a virtual input means generator that generates a virtual input means in which a blank is provided; and a password generator that generates a one time password using an initial value, reference information and a blank.

Abstract: Disclosed are a one time password generation device and an authentication method. The one time password generation device includes: a reference information generator that generates reference information; a virtual input means generator that generates a virtual input means in which a blank is provided; and a password generator that generates a one time password using an initial value, reference information, and a blank.

Abstract: Disclosed herein are a method for providing active security authentication, and a terminal and system for supporting the same. The terminal includes a storage unit, a display unit, an input unit and a control unit. The control unit arranges a plurality of keys through an arrangement of random numbers when a security execution condition is satisfied, outputs, to the display unit, a security authentication screen based on a random-number matrix in which at least some keys in key regions adjacent to an item key among the plurality of keys arranged by the arrangement of the random numbers are set to exception keys that a user must not press, and decide that the terminal is used for an illegal use when the exception keys are included in an input information generated through the input unit.

Abstract: One-time password (OTP) generation apparatus and method using virtual input means are provided. Reference information generated by a reference information generation unit is compared with identification information. When the reference information is identical to the identification information, a value corresponding to indication information is generated as an OTP.
