摘要： Methods and systems are provided for enhanced data loss prevention. The enhanced data loss prevention may be applied to data that is structured and/or semi-structured data, with the data comprising a plurality of records and a plurality of categories, with each record comprising a plurality of fields, each of which being associated with a different one of the plurality of categories. The enhanced data loss prevention may comprise selecting a subset of records of the data, with the selected subset comprising at least two records having between then one or more records not included in the subset. The fields of the selected subset may be scanned for sensitive information, and a likelihood to contain the sensitive information may be computed for each category based on the scanning. A subset of categories may be selected based on the computed likelihoods, and the sensitive information in the selected subset may be searched.

The monopole conductor may be connected to a first signal feeding line. The first ground conductor may be connected through a ground connector to ground potential. The first ground conductor may be further connected to a second signal feeding line. The second ground conductor may connected to ground potential located on a particular side of the substrate. The planar antenna may be configured to transmit and receive radiation in two mutually cross-polarized modes.

摘要： Methods and systems for implementing and operating antennas, particularly multiple-input and multiple-output (MIMO) antennas. An example antenna may include a planar dielectric substrate, a primary conductive area on a first surface of the planar dielectric substrate, a first secondary conductive area on the first surface, and a second secondary conductive area. The primary conductive area has a shape that defines at least a first region and a second region of the first surface, with the first region bounded by at least a portion of the primary conductive area, and the second region including a remaining portion of the first surface. The first secondary conductive area may lie in the first region of the first surface, and the second secondary conductive area may lie in the second region.

摘要： Methods and systems are provided for enhancing security of encrypted messages. One or more bits may be selected in an encrypted message, with the one or more bits being selected such that there is no sequence of consecutive bits in the message, having a length that is greater than or equal to a defined threshold value, that is free of bit errors. An adjustment may be applied to the encrypted message prior to transmitting the message to introduce bit errors in the message, with the adjustment being configured to affect the one or more selected bits. The adjustment may include inverting the one or more selected bits. The one or more bits may be selected and/or adjustment may be configured to reduce detectability of an encryption key used in encrypting messages.

摘要： Methods and systems are provided for selectable data transmissions. A user profile may be maintained, with the user profile including a list of authorized remote mobile computing devices and respective connection information for video communication, with the plurality of authorized remote mobile computing devices being authorized for video communication, and other remote mobile computing devices not being authorized for video communication. When a request to initiate video communication with a particular remote mobile computing device is received, a determination may be made, based on the user profile, that the particular remote mobile computing device is authorized. Respective connection information for the particular remote mobile computing device then may be assessed, and captured video communication data may be transmitted for the requested video communication according to the user profile such that the captured video communication data may be displayed at the particular remote mobile computing device as it is received.

摘要： Systems and methods are provided for determining location area of mobile user devices. In a mobile device, a first area probability as a likelihood that the mobile device is located within a first area and a second area probability indicative of the mobile device being located within a second area may be determined, with the first area probability determined based on a first probability and a second probability, and the second area probability determined based on a third probability and a fourth probability. The first probability, second probability, third probability, and fourth probability are determined based on assessing strength received in the respective area from a first base station or a second base station. A determination of whether the mobile device is located in the first area or the second area is made based on the first area probability and the second area probability.

摘要： A computer system determines location probabilities for defined sub-areas (41, 43) of a geographical area (4), e.g. for squares arranged in a grid (40), based on field strengths expected in the small sub-areas (41, 43) from the antennas (A1, A2 A3, A4), and based on the antenna used by the mobile communication terminal. The location probabilities indicate for a sub-area (41, 43) the probability that the mobile communication terminal is located in the respective sub-area (41, 43). The computer system determines at least one ellipse defining the location area, based on the location probabilities of the sub-areas (41, 43). The location probabilities make it possible to determine elliptical location areas of mobile users much smaller than the area each antenna does cover physically, but without the need for measuring at the mobile communication terminal signal properties such as signal strength or observed time differences.
