A method (as well as system and signal-bearing medium) of processing biometric data, includes receiving biometric data including a data set P, selecting a secure hash function h, and for each data set P to be collected, computing h(P), destroying the data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P).

Nonlinear optimization is applied to resource allocation, as for example, buffer pool optimization in computer database software where only the marginal utility is known. The method for allocating resources comprises the steps of starting from an initial allocation, calculating the marginal utility of the allocation, calculating the constraint functions of the allocation, and applying this information to obtain a next allocation and repeating these steps until a stopping criteria is satisfied, in which case a locally optimal allocation is returned.

A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as a first gray level, generating an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level and computing a change in pixel error for a first pixel. The change in pixel error is computed by identifying a first pixel indicated in a valid pixel map, toggling the first pixel with all the possible output states and swapping the first pixel with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met.

A system for resource allocation in peer to peer streaming includes steps of: inferring global properties of a neighborhood made up of peer nodes, wherein the global properties are inferred from a summarization of information obtained locally at each peer node; allocating resources for each peer node to its neighbor nodes in accordance with propagated dependency information; and periodically updating the target rates as peer nodes join and leave the neighborhood.

A method of processing semiotic data includes receiving semiotic data including at least one data set P, selecting a function h, and for at least one of each data set P to be collected, computing h(P), destroying data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P). The method further includes selecting a private key/public key (K, k) once for all cases, one of destroying the private key K and sending the private key K to a trusted party, and choosing function h as the public encryption function corresponding to k.

A system and method for improving content diversification in data driven streaming includes computing a weight factor and a qualification factor for each of at least two nodes among a plurality of nodes, based upon a bandwidth of each node. Content is pushed to a node based on the qualification factor and the weight factor of each node. The qualification factor is updated for the node which received pushed content.

摘要:
A method of embedding an image into two images by performing a digital halftoning process on a Cartesian product of color spaces to embed the image into the two images. A digital halftoning process includes an iterative isotropic halftoning process. The iterative isotropic halftoning process for each iteration if Outimage has not changed between two iterations or maximum number of iterations reached, then exit the iterations loop.

Viewing angle characteristics of a liquid crystal display (LCD) are improved by reducing the number of subpixels in an image with mid-tone luminance values. In a preferred embodiment, a first table of entries associating subpixel intensity values and subpixel luminance values for a LCD in at least one viewing angle direction is provided. A target intensity value is determined from the first table, corresponding to the average subpixel luminance over a small number of adjacent subpixels. A second table of entries associates the target intensity values with intensity values above and below the target. The adjacent subpixel intensity values are modified according to the second table, thereby reducing the number of subpixels with mid-tone luminance values. The subpixel data is preferably processed within a portion of an application-specific integrated circuit (ASIC), contained within the display module.
