Seams to be from a inserted script in order to disturbe browser fingerprinting.

I use Firefox with addon Canvas Fingerprint Defender and have similar JavaScript code injected:

<script> (function () { const toBlob = HTMLCanvasElement.prototype.toBlob; const toDataURL = HTMLCanvasElement.prototype.toDataURL; const getImageData = CanvasRenderingContext2D.prototype.getImageData; // var noisify = function (canvas, context) { const shift = { 'r': Math.floor(Math.random() * 10) - 5, 'g': Math.floor(Math.random() * 10) - 5, 'b': Math.floor(Math.random() * 10) - 5, 'a': Math.floor(Math.random() * 10) - 5 }; // const width = canvas.width, height = canvas.height; const imageData = getImageData.apply(context, [0, 0, width, height]); for (let i = 0; i < height; i++) { for (let j = 0; j < width; j++) { const n = ((i * (width * 4)) + (j * 4)); imageData.data[n + 0] = imageData.data[n + 0] + shift.r; imageData.data[n + 1] = imageData.data[n + 1] + shift.g; imageData.data[n + 2] = imageData.data[n + 2] + shift.b; imageData.data[n + 3] = imageData.data[n + 3] + shift.a; } } // window.top.postMessage("canvas-fingerprint-defender-alert", '*'); context.putImageData(imageData, 0, 0); }; // Object.defineProperty(HTMLCanvasElement.prototype, "toBlob", { "value": function () { noisify(this, this.getContext("2d")); return toBlob.apply(this, arguments); } }); // Object.defineProperty(HTMLCanvasElement.prototype, "toDataURL", { "value": function () { noisify(this, this.getContext("2d")); return toDataURL.apply(this, arguments); } }); // Object.defineProperty(CanvasRenderingContext2D.prototype, "getImageData", { "value": function () { noisify(this.canvas, this); return getImageData.apply(this, arguments); } }); // document.documentElement.dataset.cbscriptallow = true; })() </script>
