There are situation where a user sends a message, and later on refuses that he had sent that message .
-
Example:- User A could send fund transfer request to bank over internet. After the bank performs the fund transfer as per A’s instructions, A could claim that he never sent such the fund transfer instruction to the bank.
-
Thus A denies his fund transfer instruction. The principle of non-repudiation eliminate such possibilities of denying something after having done it.
