Systems and methods for providing authentication using an arrangement of dynamic graphical images, which may display a popup element while a pointing device indicator is over a graphical image. The graphical images can be arranged as a grid or matrix for presentation on a device display for authentication of a user. The kinds of graphical images can be derived from a designated authentication category and non-authenticating categories. A series of password elements corresponding to the graphical images can be displayed with the graphical images. The user may enter the series of one or more password elements corresponding to graphical images from the authentication category which combine to form a password entry. An authentication server can compare the password entry to an authentication password corresponding to the particular arrangement of dynamic graphical images. The selection of graphical images, their arrangement and their corresponding password elements, may dynamically change in between authentication processes.

Methods and systems for graphical image authentication

A method and system for protection of and secure access to a computer system or computer network. The method includes the steps of receiving a first login account identifier, such as a user name from a user in communication with the computer system or network. A determination is made if the user is recognized and enrolled from the first login account from the first login account identifier. If the user is recognized, a grid of randomly generated visual images is displayed including one visual image from an image category which has been preselected by the user upon enrollment. An image category identifier is randomly assigned to each visual image in the grid. An image category identifier, second login account identifier, such as a password, is entered and received. If the login account identifier and the image category is validated, access is permitted to the computer system or network.

The present invention systems and methods enable configuration of functional components in integrated circuits. A present invention system and method can flexibly change the operational characteristics of functional components in an integrated circuit die based upon a variety of factors including manufacturing defects, compatibility characteristics, performance requirements, and system health (e.g., the number of components operating properly). Functional component operational behavior is tested and analyzed at various levels of configuration abstraction and component organization (e.g., topological inversion analysis). The testing and analysis can be performed in parallel on numerous functional components. Functional component configuration related information is presented in a graphical user interface (GUI) at various levels of granularity and in real time. The graphical user interface can facilitate user interaction in recognizing failure patterns, production test tuning and field configuration algorithm adjustment. The testing and analysis information can also be organized in a variety of convenient database formats.

This disclosure describes techniques for removing vertex points during two dimensional (2D) graphics rendering using three-dimensional (3D) graphics hardware. In accordance with the described techniques one or more vertex points may be removed during 2D graphics rendering using 3D graphics hardware. For example, the techniques may remove redundant vertex points in the display coordinate space by discarding vertex points that have the substantially same positional coordinates in the display coordinate space as a previous vertex point. Alternatively or additionally, the techniques may remove excess vertex points that lie in a straight line. Removing the redundant vertex points or vertex points that lie in a straight line allow for more efficient utilization of the hardware resources of the GPU and increase the speed at which the GPU renders the image for display.

Discarding of vertex points during two-dimensional graphics rendering using three-dimensional graphics hardware

An edge function is computed from two vertex coordinates given by a rendering target line. Gradient determination is then performed on the edge function, and the functions representing two shift lines that are formed by translating the rendering target line in the y-axis direction or x-axis direction depending on the angle formed by the rendering target line and the x-axis of the rendering plane coordinate system by 0.5d and −0.5d will be computed, where d denotes the width of one pixel. Then, the number of subpixels included in a parallelogram, which has four points of the starting points and ending points of the two shift lines as vertices, is acquired so as to determine the pixel value of each pixel based on the number.

Drawing method, image generating device, and electronic information apparatus

A drawing processing apparatus is provided to solve the problems in which pixels of a drawing primitive with sub-pixel information may have an increased amount of data causing a burden on implementation. A setup processing unit sets up various parameters to allow a digital differential analyzer (DDA) to process the stream of a drawing primitive supplied from a primitive input unit. The DDA performs DDA processing on the drawing primitive supplied from the setup processing unit for conversion into pixel data. The DDA performs the DDA processing on a per rectangular pixel set basis along a scan line to output the pixel data of the drawing primitive on a per rectangular pixel set basis. A compression encoding unit encodes the sub-pixel information of each pixel contained in the rectangular pixel set by run length encoding for output to a FIFO buffer.

If an acute angle between the line 66 to be drawn and the x-axis of a drawing plane coordinate system is not larger than 45°, functions of two shift lines 68 to which the line 66 to be drawn is translated by 0.5d and -0.5d along the y-axis are calculated, where (d) is the width of one pixel. If the acute angle between the line 66 to be drawn and the y-axis of the drawing plane coordinate system is larger than 45°, functions of two shift lines to which the line 66 to be drawn is translated by 0.5d and -0.5d along the x-axis are calculated. Sub pixels included in a parallelogram abcd whose vertices are four start points and end points of the two shift lines 68 are next counted, and a pixel value of each pixel is set accordingly.
