JavaScript: how to use data but to hide it so as it cannot be reused

Question

Hi all.

I've some data that i'd like to publish just on one website, ie. it should not be reused on other websites. The data is a set of numbers that change every day, our journalists work to get hard gather it.

Is there any way to hide, crypt, etc. the data in a way that it cannot be reused by others? But to show it in a graph in the same time?

I found the ASCII to HEX tool that could be used for (http://utenti.multimania.it/ascii2hex/). I wonder if you can suggest other ways. (Even if I have to completely change the strategy.)

Many thanks!

Answer 1

You can publish a watermarked image containing the graph.

Answer 2

Well, if you can see it then you can reuse it.

You could use images to show graphs and have a watermark.

Answer 3

Since the JavaScript needs to decode it in order to display the data, any encoding is easily broken by reading and reverse-engineering the JavaScript code.

If the data is only used in a graph, then may be you could generate the graph server-side.

Answer 4

You can encrypt javascripts, or just the data used but if someone really wants to they can decrypt it.

I would suggest fetching the data in the backend and dynamically build an image to display the graph(s). Simple image libraries such as gd+ for php can easily accomplish this.
