MY paper problem is here - 1.input a text 2.detect the edhe of the input image by robert mathod & use these pixel as the hash key 3.read a text and store the data in array list(Lc). 4. the hash function uses the hash key and text data to generate a pattern i.e. sequence of hash value where data will be stored. 5.generated pattern is stored in the array list Lp. 6.the ASCII value of Lci IS REPLACED with blue byte of Lp. 7.the output is the encoded image. MY main problem in this i have not understand what type of hash function used for this purpose,because in paper clearly not mentioned?please suggest me sir

Closed means the Question is marked as no longer active. It will not appear in the index of questions that others see, and others can no longer find it through content searches. It can, however, be read by people who know the question number, or by looking through the list of questions you posted.

A closed question that is inactive for 10 days will be automatically deleted.

This Question was closed because it is not a MATLAB question. Theory matters should be researched elsewhere.
