Abstract: Accuracy of rendering server-provided content at a client device can be automatically verified. To this end, content can be provided in a non-image format to the client device via a communication network, such that the client device renders the content to generate a rendered image. The content is rendered using a canonical rendering component to generate an expected rendered image. An expected result corresponding to the expected rendered image is generated, and the expected result can be be compared to verification data generated based on the rendered image to determine whether the client device correctly generated the rendered image.

Abstract: A system for adjusting displayed content length as a function of map scale may include one or more computing devices and a memory. The one or more computing devices may receive a query, retrieve a content item based at least in part on the query. The one or more computing devices may further determine a first amount of the content item to display based at least in part on a first zoom level, determine a second amount of the retrieved content item to display based at least in part on a second zoom level and provide the map to the user device for display, where the first amount of the content item is overlaid on the map when the map is displayed at the first zoom level and the second amount of the content item is overlaid on the map when the map is displayed at the second zoom level.

Abstract: A method for printing a security document on a substrate is disclosed. Firstly, a first reference image of a reference region of the substrate is generated, the image being indicative of an inherent characteristic of the substrate in the reference region. This is followed by generating encoded data indicative of the inherent characteristic of the substrate. Finally, the encoded data is printed over the reference region of the substrate, thus effecting the print of the security document.

Abstract: A method of authenticating a first document (270) including content (271) and a barcode (272). The barcode (272) comprising barcode elements each having a predetermined form. A plurality of the barcode elements of the barcode are detected in a representation of the first document (270). A visual difference between each of the detected barcode elements and the predetermined form of the barcode element is determined. The barcode (272) is decoded to determine a second document. The first document (270) and the second document are compared based on the determined visual difference, in order to authenticate the first document (270).
