A control device (120) receives, via a first communication channel, a web page request from a control agent (102) implemented in a browser (101), the browser (101) being installed in a computer device operated by a user.

The control service (130) executes a security check on said requested web page by checking whether the requested web page is included in a blacklist or a whitelist and also by checking certain risk control criteria of the requested web page. Finally, in response to receipt a result of said security check, the control device (120) allows or denies access to said web page.

Abstract: A method for modelling a shape of data in a GAN comprising a generator agent (G) for generating synthetic data (110, 220) and a discriminator agent (D) for distinguishing between the generated synthetic data (120, 220) and real original data (110) that follow an arbitrary, continuous or discrete, distribution defined by a n-dimensional vector of input variables xi. The method, before generating output synthetic data (220), computes an Inverse Smirnov transformation fSi?1 for each of the n input variables xi and attaches an activation function (200) to the generator agent (G), wherein the activation function (200) is a n-dimensional vector faG formed by the computed Inverse Smirnov transformations, faG=(fS1?1, fS2?1, . . . , fSn?1).
