|20100202701||MULTISCALE EDGE DETECTION AND FIBER ENHANCEMENT USING DIFFERENCES OF ORIENTED MEANS - Method, apparatus and computer program product that uses a novel algorithm for edge detection suitable for both natural as well as noisy images. A scale adaptive threshold is used along with a recursive decision process to reveal the significant edges of all lengths and orientations and to localize them accurately even in low-contrast and very noisy images. Further the algorithm is use for fiber detection and enhancement by utilizing stochastic completion-like process from both sides of a fiber. The algorithm relies on an efficient multiscale algorithm for computing all “significantly different” oriented means in an image in 0(N log p), where N is the number of pixels in the image, and p is the length of the longest structure of interest. Experimental results on both natural and noisy images present confirmation of the method, apparatus and computer program product.||08-12-2010|

|20100005533||METHOD AND APPARATUS FOR PROTECTING RFID TAGS FROM POWER ANALYSIS - RFID tags were believed to be immune to power analysis since they have no direct connection to an external power supply. However, recent research has shown that they s are vulnerable to such attacks, since it is possible to measure their power consumption remotely via a completely passive attack. The method and apparatus of the invention protects RFID tags against simple and differential power attacks. The invention is particularly useful regarding inventory control systems or secure documents such as epassports. The basic technique is to use two capacitors embedded in the RFID tag in lo such a way that at any given time one of them is storing energy that is being generated by the charge pump of the tag that sucks energy from the electromagnetic or magnetic field of a tag reader, and the other one is discharging and powering the computational element of the tag chip.||01-07-2010|
|20090225985||METHOD, APPARATUS AND PRODUCT FOR RFID AUTHENTICATION - A method and apparatus for repeated communication sessions between a sender (e.g., RFID tag) and a receiver (RFID reader) that employs a proactive information security scheme is based on the assumption that the information exchanged during at least one of every n successive communication sessions is not exposed to an adversary. The sender and the receiver maintain a vector of n entries that is repeatedly refreshed by pairwise XORING entries, with a new vector of n entries that is randomly chosen by the sender and sent to the receiver as a part of each communication session. Also, a computational secure scheme based on the information secure scheme is employed to ensure that even in the case that the adversary listens to all the information exchanges, the communication between the sender and the receiver is secure. In particular, the scheme can be used in the domain of remote controls (e.g., for cars).||09-10-2009|
