Abstract: This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base Tbase (i) synchronized with card i, the method comprising the steps of: receiving at a time TS a dynamic card verification dCVV code value generated by card i; providing a set of at least two dCVV code corresponding to two successive dCVV time periods; if the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase(i) of the card; updating time base Tbase(i) by addition of a time drift correction equal to the minimum possible time drift Min_td.

Abstract: A method and system to help photographers to take better quality pictures of landmarks and scenes are disclosed. A user is guided with examples of existing quality images, which are extracted from a database, of the same or similar landmarks or scenes. The method includes taking a query photograph that may include an image associated with a GPS location and other metadata, and using information extracted from the image to retrieve existing, similar images. The images retrieved may be ordered according to different criteria. When a user selects one as a model image, the user is provided with assistance for taking a target photograph of similar quality.

Abstract: A method is provided for selecting fields of an electronic form for automatic population with candidate text segments. The candidate text segments can be obtained by capturing an image of a document, applying optical character recognition to the captured image to identify textual content, and tagging candidate text segments in the textual content for fields of the form. The method includes, for each of a plurality of fields of the form, computing a field exclusion function based on at least one parameter selected from a text length parameter, an optical character recognition error rate, a tagging error rate, and a field relevance parameter; and determining whether to select the field for automatic population based on the computed field exclusion function.
