A method for modifying a subtitle of a video frame. Subtitle text representing audio content of a video frame and font attributes of the subtitle text are received. A color of the subtitle text is identified, based on the font attributes of the subtitle text. A geometric region within the video frame corresponding to a display area of the subtitle text. A predominant color of the geometric region within the video frame is calculated. A level of similarity between the color of the subtitle text and the predominant color of the geometric region is determined. Rendering information of the subtitle text is calculated, based on the level of similarity, and a modification of the subtitle text is performed by applying the rendering information to the subtitle text, such that the modification reduces the similarity level during display of the video frame.

An electronic tag programmed with an identification in a seat belt assembly is identified by reading the programmed identification via an electronic device embedded in a seat. In response to identifying the electronic tag, a determination is made that an occupant has not fastened a seat belt of the seat belt assembly to secure the occupant in the seat.

Method, system, and computer program product for detection of securely fastened seat belts

A computer implemented method for preventing fraudulent activity on a user account includes analyzing a set of personal information corresponding to a user to identify one or more travel events, wherein each travel event indicates a corresponding timeframe and location, receiving an access attempt made with respect to a user account and a current location corresponding to the access attempt, determining whether the current location corresponds to a location indicated by the one or more identified travel events, analyzing one or more external sources to determine whether the current location is explainable responsive to determining the current location does not correspond to a location indicated by the one or more identified travel events, and denying the received access attempt made with respect to the user account responsive to determining the current location is not explainable.

Cognitive fraud prevention

A method for encoding information within a feature of a document. The method includes at least one computer processors determining information to encode within a document. The method further includes identifying a feature within the document to encode information within based, at least in part, on metadata of the document corresponding to the feature. The method further includes determining a set of geometric properties of one or more segments of the identified feature. The method further includes encoding, by one or more computer processors, a first bit of information of the determined information within a first segment of the feature within the document by modifying one or more geometric properties respectively associated with the first segment. The method further includes outputting the document with information encoded within the first segment.

Encoding information within features associated with a document

A computer-implemented method for enhancing navigation systems and maps with security-related information includes receiving, by a computer, a map comprising one or more security areas; and also receiving dynamic information about respective conditions related to each of the one or more security areas and respective security attributes related to each of the one or more security areas. Furthermore, the computer calculates a respective risk value for each of the one or more security areas based on the respective conditions and the respective security attribute of the security area; and transmits to a user device associated with a user, risk-related information based on a current location of the user device and the respective risk values.

Additional security information for navigation systems

A method, computer system, and a computer program product for detecting and managing a vehicle violation by utilizing a plurality of feedback is provided. Embodiments of the present invention may include detecting a violation by a vehicle, wherein the vehicle includes a vehicle device, wherein nearby vehicles are notified of the violation by emitting an alarm. Additional embodiments of the present invention may include detecting a violation by a violating vehicle by utilizing sensors. Additional embodiments of the present invention may then include detecting a witness and recording feedback received by a witness. Additional embodiments of the present invention may further include evaluating the recorded feedback and gathered information on the violation and determining a sufficiency of the feedback and gathered information to verify whether the detected violation is valid. Additional embodiments of the present invention may further include storing the feedback and gathered information in a global knowledge base.
