In a secure cloud for transmitting packets of digital data, the packets may be repeatedly scrambled (i.e., their data segments reordered) and then unscrambled, split and then mixed, and / or encrypted and then decrypted as they pass through media nodes in the cloud. The methods used to scramble, split, mix and encrypt the packets may be varied in accordance with a state such as time, thereby making the task of a hacker virtually impossible inasmuch as he or she may be viewing only a fragment of a packet and the methods used to disguise the data are constantly changing.

A method of balancing a user's input to an interactive computer program with the program's output is obtained by continually measuring the difference between the user's input and the program's output and adjusting one or more parameters of the program's output so that the difference from the user's performance is progressively reduced. The adjustment may be obtained dynamically through negative feedback dampening of the measured difference (delta) between user input and program output, and / or by selection of predetermined apposite values for program output corresponding to the measurement of user input. The adjustment results in dynamic generation and / or selection of premodeled segments of interactive output in closer balance with user input. The adjustment method can be applied to video games, educational games, productivity programs, training programs, biofeedback programs, entertainment programs, and other interactive programs. In video games, the adjustment method results in balancing user performance with game difficulty for a more engaging game experience. It can also enable embedded advertising to be triggered when the user is in an optimum state of engagement. The adjustment method may be performed by projecting future trends of user performance, selecting predetermined or dynamically determined levels of value, modifying user control of input devices, or even modifying the program's challenges to user capability over time.

This invention concerns a method and system for improving the security of transaction in an emulated Integrated Circuit. During compilation time of a payment application, at least one detection agent are inserted into the code of the payment application. This detection agent is configured to detect an unauthorized use of the payment application. During a runtime of the payment application, if the detection agent result indicates “no threat detected” the payment application retrieves from a predefined map of “no threat detected”, the right value associated to the detection agent, otherwise a random false value is generated. The payment application alters at least one data manipulated during the transaction with the value retrieved or generated. A reverse mechanism of the payment application retrieve the right value and apply a restoration process to the altered data with the retrieved right value. The payment application computes a cryptogram from the restored manipulated data. From the computed cryptogram, a third party can authorize or reject the transaction.

The disclosure relates to obstacle array devices (also known as bump array devices) for separating populations of particles by size. Improvements over previous obstacle array devices are realized by causing the fluid velocity profile across gaps between obstacles to be asymmetrical with respect to the plane that bisects the gap and is parallel to the direction of bulk fluid flow. Such asymmetry can be achieved by selecting the shape(s) of the obstacles bounding the gap such that the portions of the obstacles upstream from, downstream from, or bridging the narrowest portion of the gap are asymmetrical with respect to that plane. Improvements are also realized by using obstacles that have sharp edges bounding the gaps. Other improvements are realized by selecting obstacle shapes such that the critical particle dimensions defined by the gaps in two different fluid flow directions differ.
