Abstract: A mobile terminal receives trustworthiness information for a software application by receiving a voucher that indicates the trustworthiness of that application as represented by a third party. To ensure the integrity of this information, the mobile terminal authenticates the voucher and verifies that the software application is the one having its trustworthiness indicated by the voucher. Given such indications of trustworthiness, a user of the mobile terminal may decide whether install and run it. If decided in the affirmative, the user may form his or her own basis for the trustworthiness of the software application. Accordingly, the mobile terminal may also create a new voucher that indicates the trustworthiness of the software application as represented by the user. With third parties representing the trustworthiness of software applications in this manner, their development is not hindered by the imposition of security requirements on application developers.

Abstract: View synthesis is performed based on obtained texture data and a depth map. The resolution of the depth map is lower than that of the texture data by a ratio dw in the x direction and by a ratio dh in the y direction. Texture pixel positions x, y are transformed into non-integer depth map pixel positions by performing divisions x/dw and y/dh and these non-integer depth map pixel positions are rounded to integer depth map pixel positions, and a view is synthesized based at least on the obtained texture data and depth map values at the integer depth map pixel positions and/or adjacent positions.

Abstract: A web browser client includes an aggregated web application runtime environment that controls access by a program fragment of an aggregated web application to a resource therein based upon the originating domain of the program fragment To do so, the aggregated web application runtime environment appends an access attribute to the Document Object Model (DOM) node associated with the resource This access attribute is associated with a plurality of access rights definitions where each access rights definition defines a set of access rights to the resource for program fragments originating from a domain with a specific access rights status Accordingly, the aggregated web application runtime environment sets one or more access rights statuses of the originating domain of the program fragment, and thereafter, grants or denies the program fragment access to the resource based upon one or more sets of access rights defined for that program fragment
