Watermarking

I am doing a project in digital watermarking. Currently I need to know the available methods to convert a text file(.txt extension) into a stream of bits(1s and 0s). Is there any function in Matlab to perform this operation or should I try any alternative method?? Pls help me soomeone.......

Hi,

just read in the file as bits:

% open the file
fid = fopen('yourfile.txt', 'rt');
% read as unsigned 1 bit data:
data = fread(fid, '*ubit1');
% done:
fclose(fid);
