A method for embedding an entire image, audio or video watermark sequence within another image, audio or video data sequence with minimum loss of data quality is presented. The method exploits the de-correlation property of data coefficients in the orthogonal transform domain, similar to the application in data compression through transform coding. The present invention describes the usage of a Discrete Cosine Transform as the embedding domain. However, other orthogonal transforms such as Fourier, Walsh-Hadamard, Haar, Sine and Wavelet can also be used for this operation. A unique key derived adaptively from spatial locations registering the thresholds of the ac transform energies is used to unlock or de-watermark the embedded image or audio sequence. Moreover, an exponential filter has been developed to compress and expand the watermark coefficients prior to the embedding and retrieval process. The method can be used in resolving multimedia copyright protection issues arising on the Internet and in the music industry, such as the inclusion of a company's logo or an artist's recorded voice. The method can also be incorporated as a built-in feature for digital recording devices, such as still and video cameras, as well as more recent devices such as VCD and DVD players. Moreover, the method can be applied to the commercial and service sectors, where security in transmission and reception of private information in terms of speech or image is of the utmost importance.

To help ensure high data quality, data warehouses validate and clean, if needed incoming data tuples from external sources. In many situations, input tuples or portions of input tuples must match acceptable tuples in a reference table. For example, product name and description fields in a sales record from a distributor must match the pre-recorded name and description fields in a product reference relation. A disclosed system implements an efficient and accurate approximate or fuzzy match operation that can effectively clean an incoming tuple if it fails to match exactly with any of the multiple tuples in the reference relation. A disclosed similarity function that utilizes token substrings referred to as q-grams overcomes limitations of prior art similarity functions while efficiently performing a fuzzy match process.

To facilitate that, the MCD may be placed in front of steering wheel, and, if applicable, also in coupling with movement of steering wheel. The MCD may perform relative positioning map-matching lane correlation and GPS-update-interval speed positioning to improve data quality regarding vehicle moving status.

A vertical search engine may rank items based on both the quality of data associated with each item and the popularity of each item. The vertical search engine may access data associated with items from a variety of different sources, including feed sources and crawl sources. Data quality inputs are determined for each item based on the quality of the data associated with each respective item. In addition, popularity inputs are determined for each item based on user interest in each respective item. A global rankings score is then calculated for each item based on the data quality inputs and popularity inputs for each respective item. The global ranking score may be used to order search results for search queries in such a way that items from feed data and items from crawl data may be displayed in a unified manner, rather than being segregated by data source.

A computer assisted navigation system determines a recommended route for a vehicle to travel between a source and destination location, and provides exception notifications in some events where the vehicle travels a route different that the recommended route. The vehicle includes a navigation system that has a location monitoring component. It is determined if the location of the vehicle is different than a location along the recommended route. An exception notification is generated when the vehicle is not along the recommended route it is likely that the reason the recommended route was not used is because the recommended route is not the optimal route between the source and destination locations.
