Extensive Approach for Strong Password Generation Using Content-Color Mechanism

In Information security, access control is one of the most fundamental requirement. This can be achieved by assigning proper authentication credentials. In usual case we use the alphanumeric password strings to preserve the authentication. But it has several drawbacks, as all possible password strings which may be generated from keystrokes of the keyboard may be guessed or can be hacked by various attacks or some automated software tool may be used to crack the same. But here in this paper we are proposing a Content-Color method of Image fusion which will use multiple images to produce the password string. Once all these multiple images are fused, on the resultant fused image we will perform multi-share Visual key cryptography. Finally one such share can be selected randomly to generate the password string.
