I'm going to do a very simple watermarking. I want to embed a signature on unused LUTs. could you please tell me how I can do it? Thank you very much.

You cannot "embed" such a signature on LUTs, because without power every SRAM based FPGA (=99% on the market) forget whats in the LUT. And so all the LUTs have to be reloaded from some config flash during powerup...

maybe it is possible to burn some of the luts individually by applying an overdose of power by toggling them very rapidly? Problem: how to read them back?

You have no kind of access to the LUTs from outside. If you select a LUT via JTAG then you simply will destroy some surrounding IO drivers by applying high voltage to those pins.
