Thread Subject: how to check whether an image can be edited or not in MATLAB?

Hello,

I am working on a project in Image Processing area, and as a part of the project I have to write a code in matlab that must check whether the input image provided through imread function is a secured image (i.e. image that cannot be edited or modified) or not a secured image.

I want to know how to check whether an image can be edited or not in MATLAB? i.e. How to check whether an image is secured (encrypted) or not?

Please provide a solution to this problem. Thanking you in advance !!!

If by 'secured' you mean read-only, use FILEATTRIB. If that's not what you
mean, you'll have to clarify exactly what you mean when you use the term
"secured image".

try
  goodImage = imread(fullFileName);
  % If you get to here, it can be read.
catch ME
  % MATLAB can't read it with built-in functions.
  msgbox(ME.message);
