Skimming modules can be attached at self-service terminals, such as an automated teller machine or account statement printer, by manipulation with fraudulent intent by third parties who attempt to read the data from a magnetic stripe card introduced into the card reader (10). In order to counteract this problem effectively, a protective device (26, 28) is proposed that contains a protective generator (26) and an inductor (28) operatively connected thereto to generate an electromagnetic protective field (29) that is suitable for compromising the function of the spying device (SM), wherein the protective device (26, 28) generates an electromagnetic protective field (29) with a protective signal that simulates the type of signal that occurs when magnetic stripe cards are read. Through the protective field a special protective signal is induced in the potentially present skimming module to imitate the reading of the magnetic stripe card. The skimming card reader reads a pseudo magnetic stripe card, or is at least confused when spying on the genuine magnetic stripe card. In particular, the protective signal can contain pseudo data that are mixed with the actual card data at demodulation or suppress said data completely (capture effect) so that the third party ultimately obtains unusable data.

The computational cost of many statistical modeling algorithms is affected by the input / output (I / O) cost of accessing out-of-core training data. This is an important challenge for emerging data mining applications, where the amount of training data can be potentially enormous. A heuristic approach to this problem is described. This approach is based on constructing a simple probability model from the large training data set, and using this model to generate simulated pseudo data for some aspects of the statistical modeling procedure. This approach is illustrated in the context of building a Naive Bayes probability model with feature selection. Here, the usual algorithms would require numerous data scans over the massive training data set, but our heuristic obtains models of comparable accuracy with just two data scans.

In this invention, image data expressed by one component is encoded at a high speed by using a color image lossless encoder. To do this, a color conversion unit converts color image data read by a document reading unit into C, M, Y, and K data. In a color reading mode, a switching unit directly outputs the C, M, Y, and K data to an encoding unit. If the reading mode is a monochrome reading mode, the switching unit neglects the C, M, and Y components of the C, M, Y, and K data. Every time four K components are input, the switching unit supplies the four K components to the encoding unit as pseudo data of C, M, Y, and K color components. The encoding unit lossless-encodes the received C, M, Y, and K component data.

Method for more rapidly forming a stochastic model of Gaussian or Gaussian-related type, representative of a porous heterogeneous medium such as an underground reservoir, constrained by data characteristic of the displacement of fluids and punctual observations, these observations being uncertain and characterized by a probability law. It is based on a method for transforming static information, given in form of probability laws, into Gaussian punctual pseudo-data. This transformation technique has the advantage of being fully compatible with a gradual deformation method. In fact, it makes it possible to minimize an objective function J measuring the difference between the dynamic data (production data for example) and the corresponding responses simulated for the reservoir model considered. Minimization is carried out by combining realizations of a stochastic model on the one hand for the reservoir model and, on the other hand, for the Gaussian pseudo-data representative of the static information. During the minimization process, the combination coefficients are adjusted and the realizations allowing to reduce the objective function are identified. Application notably to petroleum reservoir development for example.

Disclosed are methods and systems for frustrating statistical attacks. A sender and receiver agree upon an encryption and integrity encoding scheme. For each “real” data packet, the sender generates integrity information, puts it in the packet, and then encrypts the packet using the agreed-upon scheme. Every now and again, the sender generates a “pseudo-data” packet encoded using a scheme different from the agreed-upon scheme. When the real-data and pseudo-data packets arrive at the receiver, they are decrypted using the agreed-upon scheme, and their validity is verified using the integrity information. Verification succeeds for real-data packets, and their data are accepted as valid. Verification fails for pseudo-data packets, however, and their data are discarded. An eavesdropper cannot differentiate pseudo-data from real-data and so cannot help but use all of the packets in its analysis. This mingling of pseudo-data with real-data frustrates the eavesdropper's statistical attempt to uncover the agreed-upon encoding scheme.

A tool for testing a double data rate (“DDR”) memory controller to ensure that data strobe transitions are aligned with data eyes to achieve a desired data integrity during data transfers between the memory controller and the memories. After the memory controller completes its training sequence during the initialization process, the tool sweeps the data strobe transition across the data eye. At each timing step during the sweep, several tests may be conducted to check for integrity of functionality. The tool thus generates a pass / fail margin table. The locations of the data strobe transitions selected by the memory controller during its previously run training sequence are then added to this tool-generated margin table. The result is essentially a pseudo data eye, reconstructed including the data strobe transition with the data eye. An inspection of the location of the data strobe transition with the data eye may be utilized to show the range of timing steps available before the data strobe transition would fail to capture valid data from the incoming data eye.
