What original topic on computer vision in the field of information security to choose for a term paper?

Question

Image processing

I'm looking for a topic for a term paper on computer vision. Standard tasks (number plate recognition, face detection and recognition) have already been solved one way or another. Advise something more or less original, about the same kind (Without augmented reality and work with three-dimensional graphics), it is desirable that the good old OPENCV could be used for the solution and the topic was related to security. Thanks in advance.
