摘要： A method of hiding a pattern in a host image increases and decreases parameter values at randomly selected host image locations assigned to respective first and second groups. The alteration modifies the statistical behavior of a test statistic equivalent to a linear combination of a large number of instances of respective functions, associated with the pattern, of the parameter values at first and second group locations. The presence or absence of the pattern in a test image is determined by comparing the experimental value of the test statistic associated with the pattern with the expected value of the same sum for an unaltered host image.

摘要： A technique for embedding a mark in an a printed image allows its interpretation by an inexpensive printing system. Values of a characteristic parameter are altered in a portion of the host image confined to a thread, i.e. a region of contiguous points in the image, small enough to be included in the print space treated by the printer in a single pass of the printing head.

摘要： A technique for embedding a tracking number as a series of bits in a printed image alters characteristic parameter values at a set of pseudo-random locations chosen for each bit in an embedding zone. The alteration markedly changes the expectation value of some linear combination of mathematical functions of the values at that set of locations. A marker bit encoded to a higher certainty than other bits in the string aids in orienting the zones in decoding. The tracking number is detected and identified by exploiting the behavior of sums of a large number of random variables, based on the Patchtrack approach.

摘要： A method of hiding a figure in an image replaces information from a figure-shaped portion of the image with information from another location having similar texture. The relative insensitivity of the eye to discontinuities in texture patterns having a significant high-frequency or random component minimizes the perceptibility of the replacement. The figure is revealed by autocorrelating the image containing the repeated information, and subtracting the image from a copy of itself shifted according to the arguments creating large value of the autocorrelation function.

摘要： A method of hiding information in a host audio signal introduces one or more echoes into the signal. The separation in time between the host signal and an echo is associated with the value of a datum embedded in the signal. The identity of the embedded datum is determined by observing the delay between the host signal and the echo.

摘要： A sales prediction system predicts sales from online public discussions. The system utilizes manually or automatically formulated predicates to capture subsets of postings in online public discussions. The system predicts spikes in sales rank based on online chatter. The system comprises automated algorithms that predict spikes in sales rank given a time series of counts of online discussions such as blog postings. The system utilizes a stateless model of customer behavior based on a series of states of excitation that are increasingly likely to lead to a purchase decision. The stateless model of customer behavior yields a predictor of sales rank spikes that is significantly more accurate than conventional techniques operating on sales rank data alone.

摘要： Embodiments of the invention relate to creating an operating system and file system independent incremental data backup. A first data backup of a source system and second version of the data on the source system is received. A second data backup of the second version of the data is created by determining differences between the first data backup and the second version of the data. Each portion of the second version of the data that is the same as a portion of the first data backup is referenced in the second data backup. Each portion of the second version of the data that is different than all portions of the first data backup is included in the second data backup. The second data backup is appended to the first data backup to create an incremental data backup.

摘要： A system and associated method for bulk processing of semi-structured results streams from many different resources ingests bytes, parse as many bytes as practical, and return to process additional bytes. The system processes network packets as they arrive from a computing resource, creating intermediate results. The intermediate results are held in a stack until sufficient information is accumulated. The system then merges the intermediate results to form a single document model. As network packets at one connection are consumed by the system, the system can select another connection at which packets are waiting for processing. The processing of a result at a connection can be interrupted while the system processes the results at another connection. In this manner, the system is able to utilize one thread to process many incoming results in parallel.

摘要： A communication pattern inducing system focuses on the propagation of topics amongst a plurality of nodes based on the text of the node rather than hyperlinks of the node. A node could represent a weblog or any other source of information such as person, a conversation, images, etc. The system utilizes a model for information diffusion, wherein the parameters of the model capture how a new topic spreads from node to node. The system further comprises a process to learn the parameters of the model based on real data and to apply the process to real (or synthetic) node data. Consequently, the system is able to identify particular individuals that are highly effective at contributing to the spread of topics.
