The - * purpose of the most of the wrappers can be divided into several categories: - * - * * Block APIs: some APIs are not generally needed and can be blocked for most of the pages. - * * Precision reduction: The returned value is too precise which might result into attacks on the - * browser or can be used to fingerprint users. - * * Hide information: Some APIs provide information that is not generally needed and can be hidden - * from most of the pages. - * * Provide fake information: We provide fake information mostly to confuse fingerprinters. - */ - -/** - * The object carrying all the wrappers - */ -var build_wrapping_code = {}; - -/** - * Adds a list of wrapping objects to the build_wrapping_code. - * - * This function is called from each wrapper in its file. - */ -function add_wrappers(wrappers) { - for (wrapper of wrappers) { - build_wrapping_code[wrapper.parent_object + "." + wrapper.parent_object_property] = wrapper; - } -} - -/** - * Function to be used by wrapped code used for rounding - */ -var rounding_function = `function rounding_function(numberToRound, precision) { - return numberToRound - (numberToRound % precision); -}`; - -/** - * Function to be used by wrapped code for adding randomized noise - */ -var noise_function = `let lastValue = 0; - function noise_function(numberToChange, precision) { - const noise = Math.floor(Math.random() * precision); - var value = numberToChange + noise; - if (lastValue < value) { - lastValue = value; - } - return lastValue; -}`; |
