A multimedia commerce service processing method includes the steps of receiving a signal for selecting a first product provided by the multimedia commerce service, detecting body size information of a user from login information of an account of the user who uses the multimedia commerce service, generating a first avatar graphic image including the detected body size information of the user and transmitting a signal for outputting an image of the first product in a specific area of the first avatar graphic image to a display device. A multimedia commerce service processing apparatus includes a receiving module configured to sense a signal, a communication module configured to transmit and receive data, a storage module configured to store login information of an account of a user and a controller configured to control operation of the multimedia commerce service processing apparatus.

Apparatus and method for processing a multimedia commerce service

A mobile device can send an identification code of a card reader coupled to the mobile device to a server system. In response to sending the identification code, the mobile device can receive a cryptographic key from the server system. The mobile device can receive a passcode via a user interface of the mobile device. The mobile device can then utilize the cryptographic key from the server system to facilitate secure communication between the card reader and the mobile device. Secure communication, for example, includes encrypting the passcode using the cryptographic key before sending the encrypted passcode from the mobile device to the card reader.

Software pin entry

The invention provides a computer-implemented authentication method comprising the step of enabling a user to input an identifier (e.g. a PIN) into an electronic device having a screen and a keypad operable within a keypad zone of the screen; by operating at least one key of the keypad via an image of at least part of a scrambled keypad which is displayed at least partially within the keypad zone. The user's operation of the keypad key via the image generates an encoded version of the user's intended input. In one sense the invention can be perceived as superimposing a non-functional image of a scrambled keyboard over an underlying, functional keypad. The image may be any type of electronic image, and may include a video image. The invention is particularly suited for use with, but not limited to, mobile phones, tablet computer, PCs etc. It can be implemented in any system wherein a user's identity must be verified before access is granted to a controlled resource.

Authentication method and system

A method of secured passcode entry is disclosed. The method, in one embodiment, includes: receiving a request to authenticate a user; in response to receiving the request, generating a passcode entry interface that includes a plurality of buttons for the user to compose a passcode entry, each button representing a character of a set of characters, the set of characters having a natural sequence, wherein said generating includes displaying the buttons on a touchscreen of the electronic device in an arrangement that does not reflect the natural sequence of the set of characters; detecting a touch event, represented as a coordinate on the touchscreen, interacting with the touchscreen while the passcode entry interface is displayed, wherein the touch event is indicative of at least a portion of a passcode entry by the user; and verifying an authenticity of the passcode entry based at least partly on the touch event.

Scrambling passcode entry interface

A method for secure passcode entry is disclosed. The method, in one embodiment, includes: receiving a request for authenticating a user; in response to the request, generating a passcode entry interface including buttons corresponding to character options for composing a passcode entry, wherein the passcode entry interface is used to receive the passcode entry to authenticate a user of the payment card; identifying, on a touchscreen of the electronic device, a traffic region that experienced touch events prior to receiving the request; and displaying the passcode entry interface on the touchscreen such that at least a portion of the passcode entry interface is positioned in the traffic region.

Secure passcode entry user interface

The present invention relates to a password security input system which performs authentication through input of a security password key which is obtained by applying a shift value to an actual password key, and a password security input method thereof. According to the present invention, a password security input system is configured with a user terminal comprising: a password setting module for receiving and storing an actual password which is inputted during the initial setting by a user; an input window generating module for generating an input window in which key buttons are randomly disposed in every instance where a password is inputted; a password input module for receiving keys of a security password which are position-changed by applying the same shift distance to the key positions of the actual password in the input window displayed on a screen; and a password authentication module for comparing a key shift value of the pre-stored actual password with a key shift value of a security password inputted by a user on the basis of the input window, and determining that password authentication is in success when the two key shift values are the same. According to the present invention, even if a security password is exposed to a third person, the user can maintain the actual password with a sound mind.
